Braille Group 31 Lithium Starting/Power Supply battery - F31
Braille Battery now has a commercial/industrial Group 31 lithium battery that combines high cranking power and high capacity in a single battery. This 24.5 pound lithium battery replaces an 80 pound lead battery, has more cranking power & usable power and will last up to 8+ times longer. This "all in one" solution can be used for starting and power supply applications in a variety of vehicles and in some cases require fewer lithium batteries to do the job of lead batteries. Braille lithium batteries charge FIVE times faster than lead and are more efficient when charged by solar panels and also don't self-discharge. If there is no draw on the battery, it will still be at 50% state of charge and still at 13 volts after sitting for FIVE years, just give it a top of charge and it's still within spec of new! Perfect upgrade for race car transporters, emergency vehicles, boats, lift gates and other applications.
