If you understand why car batteries fail, then you should also understand the importance of charging your car battery. On average, most batteries do not require a recharge for at least five years. That’s if you’re taking good care of your car. But if you want to maintain your battery to ensure a long life, you’ll benefit from routine charging. Why A car’s alternator is not designed to fully restore a depleted battery, but rather to maintain a healthy one. It is important to routinely charge car batteries that are used sporadically – like in a car driven only for short distances. However, whether your car sits outside or is in use every day, you can use a battery charger to keep it starting easily. Most chargers are designed to diagnose, recover, charge and maintain a wide range of batteries, in a wide range of applications. Some trickle chargers can be left on a battery indefinitely. These would be used on a vehicle that is not used all the time or is stored away for the winter or the summer. How At Batteries Plus, you’ll find chargers from leading manufacturers like Battery Tender, Schumacher and NOCO Genius®. Choose from a full selection of car battery chargers for everything from vintage 8V model vehicles to dual battery 24V systems and multi-battery, fleet operations. Once you have your charger, hook it up and the power will trickle in as it’s needed. The battery won’t be overcharged. A trickle charger is designed to be left on a car for a long period of time to recharge the battery. It slowly adds the charge to the battery and does not allow for the normal depletion of charge that batteries commonly have. Give it a full charge for a day or two. Batteries Plus has over 30, 000 batteries and trained associates there to install them, so make us your automotive battery source. Visit your local Batteries Plus store to have your battery and electrical system tested for FREE – no appointment is necessary!

Often times it can be difficult to know what to look for if you are buying an RC car for the first time, whetheryou arepurchasing one as a gift for a friend or family member. How do you tell what the battery requirements are, and what is the difference between the models? Which car is best for my needs? These are important considerations no matter who you are buyingfor, so below we have answered some of the frequently asked questions that might be useful to keep in mind whenbuying one of these Fast & Furious RC cars. How good is the battery life and remote range? First off, the cars and remotes do not come with pre-packaged batteries and so you will need to buy some along with the car itself. Most of the units will need at least 4 AA batteries for the carand a further 2 AA batteries for the remote. The battery requirements vary depending on the power of the vehicle and the type of terrain you use it on – if you are climbing hills and rocks with one of the off-road models, it is likely that the battery will drain more quickly than if you simply drive along flat frictionless surfaces. The likelihood is that you will get an average of about 30 – 40 minutes of play out of a set ofregular batteries. We recommend purchasing rechargeable batteries that you can use again and again, which will save you money in the long run.There are also testaments fromcustomers who have replaced the standard stock batteries with lithium ion batteries to extend the power and play time of these cars, but we would recommend caution here. Only modify these vehicles if you are a professional and know what you are doing, they will be perfect for casual use right out of the box. The remote range is quite short, but as these are rather inexpensive items you would expect a range of about 9 – 10 m (30 ft). Other remote controlled vehicles like the RC helicopters or drones will have far greater range, some up to 170ft (50m), but they also come at a higher price and have much more sophisticatednavigation and control systems.There are ways to boost your range that require modification to the remote itself, or you could purchase a separate remote that will work on the same frequency as the car you have. You will need to check the frequency in the details of the product before you do this. We like to think that having a bit of a jog down the road while you drive is a small price to pay forpiloting one of these awesome little cars. Whatare the size and quality like? Well, they certainly aren’t as large asa Land Rover that can be controlled by smartphone remote, but they do measure between 1/20th and 1/24th scale – that is around 7.5 X 3 X 2.5.The product information on Amazon always tells you the exact dimensions of the product, so you can compare these to some physical measurements of your own if you’re looking for a particular size. The detailing on these cars is also of avery high quality, which makes them great as miniaturecollector’s pieces. They are also not too expensive if you are building up a collection, because the non radio controlledstatic models are made frommore expensive materials – they may look better, but they can’t scoot down the roadto race against a friend.Thismeans that the radio control versions of these cars are much cheaper, and you could pick up both the off-road and superchargedversions of the Dodge Charge if you liked, oreven go for the whole collection if you wanted.

A trickle charger is used to replace the self-discharge of a battery in storage, so that the battery doesn't "go dead". All batteries naturally self-discharge to some extent, meaning that they lose capacity and the voltage drops. The amount of self-discharge that will occur in a month depends mainly on the battery type and storage temperature. The two most common types of lead-acid batteries are flooded batteries (the ones you refill) and sealed batteries like AGM or gel batteries that don't need refilling. Most starter batteries are the flooded type. Trickle chargers are most commonly used with flooded batteries, because the rate of self-discharge of a flooded lead-acid battery can be as high as 30% in a month. This means that within a few months an unused flooded battery can "go dead". That can be a real problem if that battery is needed to start a vehicle. Sealed AGM lead-acid batteries have a much lower rate of self-discharge. The loss in capacity will be about 3% of its capacity per month for a battery stored at room temperature. At 50F (10C), the loss would be approximately 1.5% per month, and at 104F (40C) the loss would be around 10% per month. Because of the lower rate of self-discharge, sealed AGM batteries can be stored for 9 months or more without "going dead". A trickle charger would only really be necessary for an AGM battery when it will sit unused for very long periods. Tips for calculating what size solar panel you'll need to trickle-charge your battery: 1. To start, you'll need to know the capacity of the battery you want to trickle-charge (usually listed on the side of the battery in "Ah" or "mAh", where 1 Ah equals 1000 mAh. If you can't find it there, try looking up the battery model online). Tip: Most car-sized starter batteries are about 100Ah 2. Next , calculate the self-discharge losses per month. If you will be storing a flooded battery in the summer, multiply the battery capacity, in Ah, times 30%. If you will be storing a flooded battery in the winter, multiply the battery capacity, in Ah, times 8%. Then, divide by 30 to find the average loss per day. Example 1: A 100 Ah flooded battery stored in the summer: 100 Ah * 0.3/30 = 1 Ah per day = daily self-discharge loss of the battery 3. Next , determine the number of full sun hours to expect at your location, based on the time of year. If you're in the US, you can use these solar insolation maps to approximate this. Note: 1 kWh/m2/day is the same as 1 full-sun hour per day. 4. Finally, divide the total capacity loss per day from Step 2 by the total number of full-sun hours per day from Step 3 to get the desired current of the panel. Example 2: The 100 Ah battery from Example 1 loses 1 Ah per day. In NH in June, the total full-sun hours per day will be 5.25 hours average. 1/5.25 = .19A (190 mA). For this case, a panel with a current output of at least 190 mA would be sufficient to maintain this battery in storage. Our 1.8W trickle charger produces 125 mA, and our 5W trickle charger produces 300 mA, so for this application the 5W charger would be the best choice. If you have a smaller battery, are storing it in the winter, and/or you are in a very sunny location, a 1.8W charger may be a better choice.

Charge Two Devices At Once Charge two devices at once, including the latest generation Apple devices, while on the road. The Belkin Dual Car Charger with included Lightning to USB cable gives you unlimited play and standby time while in the car, and keeps you and a passenger fully charged wherever you go. Universal USB 2.0 Ports The USB 2.0 Ports are universal, so you can still charge your legacy Apple devices with a 30–pin cable or other devices that use a Micro–USB cable. And you never have to share the power with your passengers—just plug in and power up at the same time. Includes Removable Lightning To USB Cable The Belkin Dual Car Charger comes with a 4-foot Lightning to USB cable, so you can charge your Lightning connector devices at the fastest possible speed. The smaller, more durable Lightning connector is reversible, which makes plugging it in easier than ever. And because it's removable, the cable can be used anywhere—plug it into your laptop to charge and sync, or use your own wall charger to charge from the wall. Great as a replacement cable or if you simply need an extra. Small, Compact and Easy To Use The low–profile design fits easily in your dash without getting in the way of your other controls. Rubber grips make it easy to insert and remove the Dual Car Charger, and the blue indicator light ring lets you know the charger is fully plugged in and your device is charging. Case Compatibility Depending on the type of case you have, you may need to remove your case before charging. If your speakers, Lightning connector port and AUX port are fully exposed when your case is on, you should be able to easily charge your device without removing the case.

The circuit has been designed to construct a practical mechanism that can easily and automatically charge batteries rated at 6 V or 12 V used in automobiles. BC557 – PNP general purpose transistors used for amplification and switching due to its low current and low voltage BC547 – NPN small signal transistors designed for general purpose switching and amplification due to its low voltage, low current and three different gain selections BD139 – NPN power transistor used for driver stages in hi-fi amplifiers and television circuits because of its low voltage at 80 V maximum and high current at 1.5 A maximum 2N3055 – a complementary Silicon Epitaxial-Base planar NPN transistor mounted in Jedec TO-3 metal case for use as power transistor One of the essential factors in the operation of this circuit is the utilization of transformer denoted as T1 which has excellent resistance and insulation for short circuits making it a good quality. It is responsible for transferring electric energy or alternating current from one circuit to another via conductors that are coupled inductively. A transformer is composed of two or more coils of conducting element, like a wire, wrapped around a core where a magnetic field is produced by an alternating current in one coli. This will induce the same current in the other coils. The transistor Q1 is conducting through voltage divider R1 and R2 while trimmer TR1 and resistor R4 are functioning as regulated current source. The Darlington pair of power transistors Q5 and Q6 is being driven by a current through R9. A Darlington pair is designed in such a way that the collectors of both transistors are attached together and the emitter of the first transistor is directly coupled to the base of the second or output transistor. The base current of the output transistor is equal to the emitter current of the input transistor. A car battery charger is normally around 6 V to 8 V while the current is around 1.2 A being handled by the trimmer TR1. As the battery is charged slowly, the voltage is gradually increasing until it reaches 7 V, which would cause D1 to conduct. The increase in voltage results to the decrease of voltage across R3 which makes Q1 to conduct. The process will continue until the circuit reaches 6 A. the transistor Q4 will be driven by the voltage drop via R10. Since the transistor Q5 is grounded, the excess current across it would remain constant for modification.

Car buyers got a garage evaluation and installation quote before they took delivery of their vehicles. They bought the charging stations (usually through their car dealers) that the automaker recommended. Fast-forward a few years and the marketplace has wrought its magic. Today, there are more than a dozen EV and plug-in hybrid (PHEV) vehicles on the market and more on the way. Owners and prospective owners of these plug-in vehicles can choose from dozens of home car-charging stations from more than a dozen manufacturers. You can shop direct from the maker online, from various home-improvement retailers or via mass-marketing sites such as Amazon.com. Or you can do it old-school and go through your car dealer. A recent survey of plug-in vehicle buyers by Ford Motor Company found that about half still use the dealer-supplied, one-stop service that provides the charging station and installation for one price. The other half now do their own shopping, both for the home charging station and for competitive bids from local electricians for installation. Having loads of choices can help save money and cut down the time you'll spend charging that new plug-in car. But making the right selection from among the options also requires a little time in order to research the choices and to process and digest all those bids that come from comparison shopping. The best charger for your home depends on several things. There's the type of plug-in vehicle you have or are planning to get. There are your plans for future plug-in vehicles. Your garage layout comes into play, as do your household electrical service and your charging patterns. Will you want to charge in the daytime, overnight or every time your pull into the driveway? An electrician qualified to install home car charging stations can help you decide things like the amperage you'll need, the right circuit breakers to install, the best cord length for your situation and where to locate the charging station to minimize installation costs. As a rule of thumb, expect to pay $600-$1, 000 for a home car charging station. You can, of course, pay less or more. We'll get into the details later. Installation costs also vary widely. A standard, problem-free home garage installation is usually somewhere between $1, 000 and $1, 500, but can be as little as a few hundred dollars or as high as several thousand dollars. We'll explain that wide range in more detail later, too. Know the Right Name First up, there's some lingo to know. In almost all cases, the charger isn't actually the thing you are going to buy and hang on the wall of your garage or carport. The charger is built into the car. (We'll get to the exception to this rule in a minute.) That box with the colored lights, long cord and connector nozzle that you're installing is properly known as the electric vehicle supply equipment (EVSE). It's OK if you call an EVSE a car charging station or home charger; almost everyone does. But by using the proper name for this unit, you'll be telling the electricians and salespeople with whom you're working that you know what you're talking about. The EVSE is a vital piece of the charging system. It's a communications and safety device. It provides a point for anchoring the charging cord between the car's onboard charger and the building's electrical service. It also controls the charging current to keep the car's batteries from overheating. It can shut down the charging in the event of an electrical short, power surge, charging software meltdown or any other malfunction. That's important because an overheated charging cord could lead to a car or garage fire. We said at the beginning of this section that the EVSE isn't the charger "in almost all cases." The exceptions are the rapid chargers that are being installed along various highway corridors around the country. These are also known as Level 3 chargers, and they are too big and complex to mount in a car. Level 3 chargers are packed into a free-standing case that's the size of a large refrigerator, or, perhaps not coincidentally, a gasoline pump. All About the Connector In addition to the communications and safety equipment, solid anchorage and a charging cord long enough to be serviceable, the EVSE supplies one additional and critical part: the connector or nozzle that plugs into the car's charging receptacle. With the exception of Tesla Motors, which prefers to go its own way, carmakers and charging-equipment manufacturers around the globe have standardized the design of the nozzle, universally called a J1772 connector. Tesla owners can nevertheless choose to install an EVSE with a J1772 connector because the necessary adapter is provided with each car. If you look into the J1772 nozzle's open end, you'll see five prongs with open centers, or ports. The top two are for carrying power. The large port in the bottom or 6 o'clock position is the grounding port. The smaller one in the 4 o'clock position is the communications port. The fifth port, in the 8 o'clock position, is the safety systems port. Cord Length The J1772 fitting delivers electricity and conducts communication between car and EVSE through an insulated copper cord. Most EVSE manufacturers offer several cord lengths, typically between 12 and 25 feet. Costs can go up considerably for every foot. The best rule of thumb is to figure out exactly where the EVSE will be mounted, where the car will be parked and where on the car the charging port is located. Then buy an EVSE with a cord that's at least a few feet longer than the distance you'll need to span. If your budget will stretch, buy the longest cord possible to give yourself room to charge while parked in various places in the garage and in the driveway. A long cord also will serve you well if you happen to buy another plug-in vehicle and its charging port is farther away from the EVSE than was the one on your initial vehicle.

Bloomberg/Getty Images There’s never been a better time to be in the market for an electric car, with a wide range of strong models from manufacturers around the world. Electric vehicles, or EVs, offer guilt-free, zero-emission driving, and though gas prices are down at the moment, the freedom from the filling station is liberating. From the selection of vehicles available to incentives offered, an EV is a great option. But the first and most important question you need to ask yourself is, “How will I charge it?” The number of public charging stations offered by cities and businesses is on the rise, but the network is still spotty compared to gas stations. Charging at home is a necessary part of owning an EV, and fortunately, there are plenty of options for getting it done. Nevertheless, the options and incentives can be overwhelming, and you also need to consider the tax advantages, which offer up to $1, 000 in incentives. Read on to learn about the different home charging options, and how to not get overcharged, overtaxed, or underpowered along the way. Option one – 120V Cord Your EV will likely come standard with a 120-volt charging cable. It has one end that fits into your EV’s unique charging outlet on the actual vehicle. The other end is a typical grounded plug that plugs into any grounded wall outlet. The insides of these cords are copper, and copper does not come cheap. If the brand you’re looking to buy from offers multiple cable lengths, the longer ones will be more expensive. Consider how far you’ll need to go to charge when looking at cables (more on that later). A 120v charger will work as your primary charger, but they’re not terribly efficient. A full charge for exhausted batteries can take more than 12 hours. If you’re not driving your EV frequently, you might be able to live with just the 120v charger, but chances are good that you’ll need something a little more robust. Option two – the 240v or “Level 2” An extended range EV like the Volt will charge in 10-16 hours on a 120v cable, and full EVs simply need more juice. A Tesla Model S adds only 3-4 miles of range per hour charged on the wall outlet, so something more is needed. It’s time to “Level Up.” As the name implies, a 240 volt charger doubles the output of a 120 volt charger. The bad news is that they’re typically optional from the manufacturer, and they need to be installed by a licensed electrician. It’s not an expensive job, though, running about what it would cost to install an outlet for an electric range or dryer. Steps to Installation Tesla Motors Contact Electrician: Very soon after purchasing your EV, notify a certified electrician. Tell them you are interested in installing a 240 volt charger for an electric car in your garage or near a spot in your driveway. Site Visit and Estimate: To get a true estimate, an electrician will likely have to come in person. Installation cost is based on how far your garage is from your house’s main electrical service, and whether the contractor needs to do any extra work to make the connection. Take notes if they get load calculations on various circuits. Note the estimate, and contact multiple electricians to get the best price. Installation: The installation itself could take less than a day, although some larger projects may require more than one visit. The electrician may need to meet with an inspector for an on-site inspection at a later date. Cost of Installation On the Nissan Leaf page at NissanUSA.com, you’ll find a home charging unit from AeroVironment that goes for 9, and 99 with professional installation. But Anthony Lambkin, manager of EV infrastructure for the Leaf is quick to point out, “We don’t have a specific partnership for home charging.” Nissan is among several automakers that are compatible with a number of third party products, like the ChargePoint Home, which starts at $549, and goes up depending on charging needs. There are many on Amazon closer to the price of ChargePoint’s product than to AeroVironment’s. With any new technology, installation prices were high at first. But as electricians become more familiar with the procedure, prices have come down. “The installation cost for my Leaf’s charging station was $300, ” explains Lambkind. Anything over $1000 and you’re paying too much. To cut costs, have the electrician just do the circuit. Once that is done, you can plug and mount in the 240V charging station hardware on your own. Location of Charger This is a bit of common sense, but is sometimes overlooked in the installation prices. Think about which way you typically park your car when you get home in the evening. Do you park the same way every night? Now think about where the charger is on the EV. EVs have their charging ports in different places. The Nissan Leaf has it on front, while the Chevy Bolt and Volt have it immediately ahead of the driver’s door. The port on the Tesla Model S is located in the outer corner of the left rear taillight. All are different so check these placements when initially shopping for EVs. Those in warmer climates might park their EV outside at night. If you go for an outside installation, make sure it has the appropriate weather and water protection. Solar MATHEISL/Getty Images If you are looking at an EV, there’s a good change you are looking at other means of reducing your carbon footprint. That could mean pairing a home charging station with solar cells. But it’s not as simple as putting panels on the roof and letting the savings come in. You may charge at night, but solar works during the day, so you’ll need solution. Battery packs used to be expensive, but as the technology advances, the prices come down. Installation prices could vary based on the product and how familiar electricians in your area are with solar. Pick a Plan, Start Charging The most expensive time for electricity consumption is between Noon and 6:00pm, while the least expensive time is between midnight and 6:00am. Many EVs allow you to set up charging times that take advantage of the lowest electrical rates in your area. Some energy providers also suggest a dedicated smart meter, which could reduce load during peak hours. This could be more expensive for you depending on your charging and driving habits, but could also cut down long-term cost. In the end, you’ll need to find the solution that best meets your driving habits, budget, and lifestyle. Armed with the information we’ve provided, you can confidently discuss your options with both your auto sales representative and your electrician

Just over 6 inches long, the PowerAll is a little big for most pockets, but easily stores in a car. PowerAll The PowerAll measures 6.5 inches long, 2.9 inches wide, and only 1.2 inches thick. This lightweight brick includes a flashlight in one end, useful when fiddling around under the hood at night, and two USB ports. The package includes an AC adapter and a 12-volt DC adapter for charging at home or in the car, and a set of clamps to attach the PowerAll to a car battery. The lithium ion battery in the PowerAll holds 12, 000mAh, but most important for jump starting a car, it cranks out 200 to 400 amps. I found multiple videos online of people jump starting big displacement V-8s with the PowerAll. I got to try this one out personally when the battery in my BMW Z3 Coupe died. That's a 2.8-liter inline six-cylinder engine. I opened up the hatch and lifted a cover in the cargo area to find the battery, thoughtfully placed by BMW to avoid weather. I plugged the battery clamp attachment into the PowerAll, then attached the clamps to the battery terminals. In the driver seat, I turned the key and the engine cranked right up, as if it had a full charge. Following PowerAll's instructions I immediately removed the battery clamps. And although it can reportedly handle about 20 jump starts, I took it inside and plugged it into the wall. PowerAll says it can handle more than 500 charge cycles, but should be plugged in once every three months to preserve the battery. At 5.5 inches, the Jumpr can easily store in a glove compartment or coat pocket. Juno Power Even more portable, Jumpr from Juno Power weighs only 7 ounces, about twice as much as an iPhone, and isn't much bigger. Its full dimensions are 5.5 inches long, 3 inches wide, and only 0.6-inch thick. The device includes a single USB outlet for charging phones and other devices, and the battery clamp attachment shown in the photo. Incidentally, this battery clamp is similar to that included with the PowerAll. The capacity of its lithium polymer battery is 6, 000mAh, part of the reason why it is so much smaller than the PowerAll. However, it still can produce 300 amps for jump-starting a car. Juno Power's website claims it will work for most four- and six-cylinder cars. Along with its small size, the Jumpr is also the cheapest of this bunch at $99. The Juno Power website notes the device is available for presale now at a special price of $69, with deliveries beginning in May. The 14-ounce Versapower comes with cables for jump-starting and charging common portable electronics. Matco Tools Those prone to trust a name brand may prefer Matco Tools' Versapower. This portable jump starter measures 6 inches long, 3 inches wide, and only an inch thick, and it weighs just 14 ounces. It also comes with an LED light, but just a single USB port. Included in the package is a battery clamp attachment along with a USB adapter ending in a 30-pin iOS device plug, a mini-USB, and a micro-USB. Similar to the PowerAll, its lithium ion battery holds 12, 000mAh. Matco claims up to 1, 000 charge cycles for the Versapower. 300 cranking amps and a peak of 400 amps can handle jump starting V-8 engines. Matco Tools says the Versapower can jump start a Ford F-150 with a V-8 18 times on a single charge. As with most portable battery devices, it is a good idea to recharge the device every three months.
