Lithium batteries have a relatively flat discharge curve when compared to a lead acid battery. The good news is that the average terminal voltage throughout discharge will be 12.8V for 12V models or 16V for 16V models. Unfortunately this can make judging the state of charge difficult when the battery is near empty. Lithium batteries at a low state of charge will still show a relatively high voltage. It is important to get to know the limits of your battery because over discharge (discharge below 10V for12V models or 12.5V for 16V models) must be strictly avoided.

DO NOT use a battery charger designed for “Flooded” or “Maintenance Free” batteries.
DO NOT use a battery charger with a “de-sulfation mode” or “float mode”.
Remove the battery charger once the battery is full meaning 100% State of Charge. Unlike lead acid batteries, over charging lithium batteries DOES NOT help them nor cause them to store more power. Instead it harms them and should be strictly avoided. Lithium cells are in a state of stress when at 100% SoC and beyond. Continuous charging must be avoided. Note from a practical point of view, the batteries can be left on a battery charger overnight but not more than 8 hours. If the system is not full in 8 hours, call tech support.
