This results in the battery being partially recharged quickly, but it requires prolonged charging to obtain a fully charged state. Neither constant current or step charging are ideal for stationary lead-acid batteries, and constant voltage charging is recommended. With constant voltage charging there are two common charging voltage levels:
There are basically three methods of charging lead-acid batteries: 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.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every six months to prevent the voltage from dropping below 2.10V/ cell. With AGM, these requirements can be somewhat relaxed.
Charging is the opposite reaction where the conversion of electrical energy in the form of current from an external source is stored as chemical energy in the battery cell. In all the cell types mentioned, the electrochemical reaction for the discharge and recharge of lead-acid batteries is basically the same.
It is safe to fast-charge all lead acid batteries with modern fast charge algorithms. Typical Charging curves for PowerStream quick chargers. This charger starts at 8 amps and maintains a near-constant current until nearly full. This is the fundamental algorithm of the PowerStream quick chargers for lead acid batteries.
How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
