The first thing that stands out about the MOTOPOWER MP00205A is its compact and extra-portable design. It weighs in at just 11.5 ounces and measures in at a mere 4.1 x 2 x 1.5 inches, making this the smallest battery charger on our list. But don’t let the MOTOPOWER’s small size distract you from its excellent ability to charge and maintain your batteries, as needed.
While we wouldn’t necessarily recommend the MOTOPOWER charger for recharging batteries that are low, it can still operate in that way. We just recommend you use it as a battery charge maintainer to keep all your batteries continuously topped off while they’re not in use. One of the other best features about this battery charger is the holes on the casing that you can use to mount the unit to the wall. This way, it can stay in place during charging, as long as you’re okay with a more permanent placement.
Check out the Battery Tender Plus 12V Charger and Maintainer as well, which is a 1.25 amp charger that chargers fast and efficiently with its float mode. It works with lead-acid, flooded, and sealed maintenance free batteries like AGM and gel cell. If you use this alongside a charge measuring device, like the TN Tonny 12V Plug In Car Battery and Charging System Tester, you can both charge your battery and stay informed on when your battery and charging system alternator’s due for a charge so that you don’t get stranded in any risky areas.

We were impressed and comforted by the TowerTop’s built-in safety features that will protect you and your battery from overcharging, overheating and short circuiting. It also features anti-reverse alarms that will notify you if you have your cables attached to the wrong side of the battery. We also really liked the bright LCD display that helps you better operate the battery charger with ease.

Just plug it into the cigarette lighter like it’s a phone car charger. Also, the LED indicators are a nice visual feature to show the battery level.

This gives you more versatility than many other battery chargers. And with a powerful 6A/12V output, this charger can easily charge up small and large batteries alike.
Another one of the Directtyteam Enhanced Edition charger’s best features is its repair mode. If you have a completely dead battery, this charger can bring it back to life, making it one of the more unique offerings on our list.

So, to narrow down the list for you, we focused on battery chargers that were versatile and extra safe to use. We tested each battery charger on a variety of different battery types, including car batteries and recreational vehicle batteries.
We also looked for battery charges that are easy to use. The best battery chargers feature either full displays or indicator lights that give you a quick idea to know exactly what’s going on with the battery and its charge. They should also be able to switch between different modes or power outputs so you can easily tailor the charge to your specific situation.
Finally, we looked for battery chargers that are durable and long-lasting. It’s likely that you’ll be moving the charger around a lot to different places in the garage or under the hood or stored somewhere in a drawer.
