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 an75 pound lead battery, hasserious cranking power & has more usable power while lasting8-10 times longer. This "all in one" solution can be used for starting (nearly double the cranking power of the best AGM batteries) and "deep cycle" power supply applications in a variety of vehicles (10 times the cycles of lead batteries including premium AGM) 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 18-wheelers, car transporters, lift gates, emergency vehicles, marine and other applications where a Group 31 battery is utilized.
