It's also cited as working well in extreme temperatures - both hot and cold. It's easy and safe to connect and disconnect, spark-proof, and checks to make sure a connection is established before transmitting power. The 1.25 amps of power provided ensures a "low and slow" charge, which is best for the health of your vehicle's battery.

It even has a "float" battery maintainer mode that will keep it at full power during periods of inactivity, compensating for the self-discharge associated with lead-acid batteries. It's an automatic charger, with charge controller which means it will shut down on its own when your battery charge is full, preventing overcharging. The best overall charger for your vehicle's lead-acid battery is the Battery Tender Plus (it works with multiple types of lead-acid batteries, including absorbent glass mat and flooded). A charger that can power up a 12 V lead acid battery in an SUV can do the same for one in a motorcycle, for instance. After all, most cars, motorcycles, SUVs, trucks and other road vehicles use lead-acid batteries, which are relatively resilient and inexpensive to manufacture. When it comes to picking the right battery charger, the kind of vehicle you drive typically doesn't play a major role. If your car needs repeated jump starts, the battery may be bad or there may be a problem with the charging system," Arman says. "You are much better off putting it on a regular charger and being patient. Arman has built fuel injection systems and wired countless cars, motorcycles and airplanes. "A jump starter provides a lot of amperage, and thus they are rather rough on batteries," says Mike Arman, an electronics expert, vocational school teacher and author of Motorcycle Electrics Without Pain. And it's much more compact than you might think.

A portable charger is also much easier than jump starting since you don't have to string bulky cables from one vehicle to another. The good news is that a portable battery charger can help you avoid the hassles that come with a dead battery, like trying to flag down a helpful stranger or waiting for someone to show up with jumper cables. Waiting around for help can be a frustrating and time-consuming experience - particularly when you have somewhere you need to go. It's a lot easier than in the past to get a jump or tow, thanks to the proliferation of cell phones, but no one wants to wind up with a dead battery.
