Braille Group 34 Lithium Starting/Power Supply battery - F34The new FleetLite F34 lithium Group 34 battery that combines high cranking power and high capacity in a single battery for commercial/industrial/automotive/marine applications. This 20.3 pound lithium battery replaces an 40-50 pound lead battery, has more cranking power & usable power and will last up to 8+ times longer than lead. This "all in one" solution can be used for starting and power supply applications in a variety of vehicles. 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 cars, trucks, emergency vehicles, boats (also replaces Group 24 size) and other common applications that use a Group 34 battery.
