LiFePO4 Battery Discharge and charge Curve
LiFePO4 batteries don''t need to be float charged because they don''t leak charge the way lead acid batteries do. If you can, disable float charging on your charge controller or battery charger. If you can''t, prevent the battery from entering float charge by setting the float voltage to that recommended in the battery manual — usually 13.6 volts ± 0.2 volts.
How Long Do Lead Acid Batteries Last?
Infrequent use of a lead-acid battery can cause sulfation, which is the buildup of lead sulfate crystals on the battery plates. This can reduce the battery''s capacity and lifespan. Therefore, it is recommended to use the battery regularly or maintain it properly during periods of inactivity.
