The all-new Start Pac® Model Li2800 QC utilizes the latest technology in Lithium batteries. These batteries provide the same power as the lead-acid type but are 42 percent lighter and 32 percent smaller. In addition, Lithium GPU batteries have two other major advantages:
1. Twice the battery life of lead-acid batteries
2. No sulfation problems (can be left in a discharged state without causing damage to the battery plates)
PLEASE NOTE: Lithium ion batteries can be damaged by deep discharges. Do not run the batteries down below 23 volts, a spike during a start is okay. Voltages below 23 begin the damage to the batteries. At 18 volts, the batteries will be damaged beyond repair.
