8/13/2023 0 Comments Best car battery chargerA “quick charge” can very rapidly (but safely) prepare a battery for use. A few chargers offer specialized modes like “desulfation,” which helps a battery regain its proper chemical balance through carefully timed charge and discharge cycles. Most chargers can also bring a depleted battery back up to full power. More to Consider: Best Automotive Accessories 2023 Įvery charger here can “maintain” a charged battery, keeping it from slowly discharging between uses. Any capability above that is mostly for mechanics who need to quickly charge or recondition batteries in the shop. If you’re worried that your pickup won’t start in the winter, 2 to 10 amps is a better bet. If you’re charging a small motorcycle battery or maintaining a good-condition battery in a cherished collector car, then a 0.75-amp charger will do just fine. The more power a charger has, the more quickly it can bring a dead battery back to life. In reality, the difference is easy to understand. Some have 40 amps and some have 0.75 amps, and yet they do the same thing. A quick stroll through a listing of battery chargers can be confounding though. Think of amps as the amount of “charge” that can be put back into the battery at any given time for example, a 10-amp charger is putting twice as much charge into the battery as a 5-amp one. PowerĬharging power is traditionally measured in amps. Last but not least, older vehicles often struggle to recharge slightly depleted batteries on the move, so starting the day with a fully charged battery can increase the life of your alternator and charging system, as well. If you rarely drive more than a few miles at a time, a charger can prevent your battery from being depleted to the point where you have a surprise no-start situation. If you regularly experience temperatures below freezing at night, particularly combined with high temps during the day, a charger with a maintenance function can significantly extend the life of your battery. (It's also nice to know it will start without jumper cables.) But there are plenty of other situations where a battery charger can make a difference. If you store a vehicle for long periods of time, you'll want a charger to keep the battery from fully depleting its charge and becoming damaged as a result. Unfortunately, there’s no such thing as a one-size-fits-all solution that works on everything from a vintage motorcycle to a prototype race car with two batteries! What To Consider With Car Battery Chargers When Do You Need a Battery Charger? I use multiple types of chargers and jump starters, from hand-held battery-powered devices to a traditional wheeled combination charger/starter. Show more The Expert: With five race cars and seven motorcycles in my shop, plus more than a few daily drivers, and tow vehicles in addition, my maintenance schedule is a lot like painting the Golden Gate Bridge: by the time I’ve finished one side, it’s time to start back at the beginning. We’ve rounded up the best options from basic no-frills car battery chargers to highly sophisticated charging stations capable of maintaining several vehicles at once. In some hybrids, it’s a bit more complicated than that, but even a Prius needs a working 12-volt battery in good condition. In a fully electric Tesla, for instance, the 12-volt battery runs the electrical accessories and is also required for a successful power-on. In traditional gas-powered automobiles, the battery turns the starter and runs all the electrical accessories, while being recharged on the move by the alternator, which is turned by the engine. It doesn’t matter if your daily driver is a 50-year-old pickup truck or brand-new Tesla-without a working 12-volt primary battery, as Bob Dylan might say, you ain’t goin’ nowhere. Some chargers also have a jump-start feature, just in case. This tool can also significantly extend the life of your battery-and given the steadily-rising prices of 12-volt batteries, just getting an extra year or two of service can pay for a car battery charger a few times over. An external car battery charger is a great way to make sure that your vehicle is always ready to start when you need it. The job of a car battery is a tough one, and it’s made worse by extremes in weather, brief commutes that don’t provide enough recharge time, stop/start systems fitted to many modern automobiles, or accidentally leaving your lights on.
