Bulk, Absorption, and Float are the 3 main charging stages of a typical lead acid battery. In addition, there could be one more stage called equalizing charge. Bulk Charging Stage So, the first charging stage is bulk, in which the battery is typically less than 80% charged.
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.
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:
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
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.
Power Sonic recommends you select a charger designed for the chemistry of your battery. This means we recommend using a sealed lead acid battery charger, like the the A-C series of SLA chargers from Power Sonic, when charging a sealed lead acid battery. Sealed lead acid batteries may be charged by using any of the following charging techniques:

Precautions during Charging Lead Acid Battery: (i) During the charging period the temperature of the electrolyte should not exceed beyond 40 to 45 °C because of the danger of plate buckling. Therefore, the electrolyte temperature is carefully watched and if the temperature approaches the danger limit before the end of the charge, the charging current should be reduced or the …
Lead–acid battery
Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.
