The lead-acid battery has not been fully charged for a long time

Lead acid must periodically be charged 14–16 hours to attain full saturation. This may be the reason why wheelchair batteries last only 2 years, whereas golf cars with the identical battery deliver twice the service life. Long leisure time allows golf car batteries to get a full charge overnight (See BU-403: Charging Lead Acid).

Can a lead acid battery be charged at a full charge?

Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.

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)
