Technical FAQs 4

How to care for lead-acid batteries?

The charging and discharging of lead-acid batteries need daily maintenance, pay attention to the charger specifications, charging environment, charging voltage when charging, and avoid deep discharge when discharging, so that the lead-acid batteries can be used for a longer period of time.

How do you charge a lead-acid battery?

PbSO4 + 2H20 + PbSO4 → Pb + 2H2SO4 + PbO2 There are basically two methods of charging lead-acid batteries and these are constant current charging and constant voltage charging. Constant current charging means that the battery charger output voltage is varied so that it supplies a relatively uniform current regardless of the battery state of charge.

What are the characteristics of lead-acid battery?

1. Charge and discharge characteristics The characteristics of Lead-acid battery during charging and discharging, including the change of terminal voltage over time and the influence of potential changes and internal resistance during charging and discharging.

How long does a lead acid battery last?

The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems)
