Frequently Asked Questions

What is the difference between the power supply and the Lithium / Lead-acid battery charger?

A power supply provides constant voltage/current, while a smart battery charger includes multi-stage charging (bulk, absorption, float) and battery-specific algorithms to ensure safe and full charging.

Does the Lithium / Lead-Acid battery charger have an automatic charge cut-off function to prevent overcharging?

Yes, all QQE smart chargers include automatic cut-off and monitoring systems to prevent overcharging, over-discharging, short circuits, and overheating.

What are the differences in the charging modes between Lithium and Lead-acid batteries? Can they share the same charger?

Lithium batteries require constant current/constant voltage (CC/CV) charging, while lead-acid uses bulk/absorption/float. Using the wrong charger can damage the battery. QQE offers dual-mode or dedicated chargers for each chemistry.
