Standard chargers typically use a constant voltage and current method designed for other battery chemistries, like lead-acid or nickel-based batteries. Charging a LiFePO4 battery with such a charger can lead to incomplete charging, reduced battery life, or even thermal runaway, which can cause overheating and potential fire hazards.
SEALED LEAD ACID (SLA) BATTERY CHARGING PROFILE. Let''s go back to the basics of how to charge a sealed lead acid battery. The most common charging method is a three-stage approach: the initial charge (constant current), the saturation topping charge (constant voltage), and the float charge.
Charging Method Incompatibility: Charging method incompatibility refers to the different charging profiles used for lead-acid and lithium batteries. Lithium batteries generally require a constant current/constant voltage (CC/CV) approach, while lead-acid batteries use a bulk, absorption, and float charging method.
Some lower-cost consumer chargers may use the simplified “charge-and-run” method that charges a lithium-ion battery in one hour or less without going to the Stage 2 saturation charge. A 3.60-volt lithium battery in a charger designed for Li-phosphate would not receive sufficient charge; a Li-phosphate in a regular charger would cause
