After getting more and more frustrated with a constant series of electric car battery chargers, I was glad to discover that there is a cheap way to save even more time with one of the cheaper yet more effective way to charge your car battery. I’ve been using a “battery acid on car battery” device called the Battery Acid on Car Batterie (BABC) that attaches to any car battery.
The Battery Acid on Car Batterie uses a tiny amount of liquid acid that is poured into the top of the battery’s battery terminal. It helps maintain the battery’s voltage even when its voltage drops to zero. The BABC also uses a microUSB connection to charge another device so you can just plug a micro USB cable into the car’s battery.
In case you were wondering, this battery acid on car battery works well on other batteries too because it keeps your car battery from going limp.
