So the charge of the aqueous sulfate ion is transferred to two conducting electrons within the lead electrode, and energy is released. Lead atom changes ionization and forms ionic bond with sulfate ion. Two water molecules are released into solution. solid. Electric field is generated at electrode surfaces.
So this includes the flooded and the valve-regulated lead acid batteries, including the AGM and GEL batteries. I will explain what is happening during the different charging and discharging stages of your Lead Acid battery, and by the end, you will understand what is supposed to happen and what to look out for in your battery bank.
Lead–acid batteries exist in a large variety of designs and sizes. There are vented or valve regulated batteries. Products are ranging from small sealed batteries with about 5 Ah (e.g., used for motor cycles) to large vented industrial battery systems for

A one-dimensional (1D) model of the positive electrode, taking into account the structural changes of the active material due to precipitation in discharge, was proposed by Simonsson 10 in 1973. The two main discharge effects, which are the gradual pore obstruction and the active surface insulation, are used to define a local discharge degree.
Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently. However, as the number of batteries in series increases, so does the possibility...
With the CCCV method, lead acid batteries are charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge.
Lead-acid batteries are typically charged in three distinct stages, each serving a crucial function in restoring and maintaining battery health: a. Bulk Charging . The bulk charge stage delivers the highest current the charger can supply, rapidly bringing the battery up to approximately 80% of its full capacity. The voltage rises during this phase until it reaches a pre
Lead-Acid Battery Construction. The lead-acid battery is the most commonly used type of storage battery and is well-known for its application in automobiles. The battery is made up of several cells, each of which consists of lead plates immersed in an electrolyte of dilute sulfuric acid. The voltage per cell is typically 2 V to 2.2 V.
VALVE REGULATED LEAD-ACID BATTERY (VRLA BATTERY) — A battery constructed with a fully enclosed case venting system sealed with a 1-way valve, under pressure above atmospheric, where venting of gasses is regulated through the valve that operates in a normally closed position. This configuration enables an oxygen charge shuttle reaction (recombination) inside the
Methods of Charging Lead Acid Battery: Direct current is essential, and this may be obtained in some cases direct from the supply mains. In case the available source of supply is ac then it is converted into dc by some means such as motor-generator set, rotary convertor set or rectifier.

Lead acid batteries need to be charged in various stages and voltages. This can be difficult to do, so the best way to charge your battery is to use a smart charger that automates the multi-stage process. These smart chargers have microprocessors that monitor the battery and adjust the current and voltage as required for an optimal charge. [4]
For larger batteries, a full charge can take up to 14 or 16 hours and your batteries should not be charged using fast charging methods if possible. As with all other batteries, make sure that they stay cool and don''t overheat during charging. Lead-Acid Battery Discharge. Sealed lead-acid batteries can ensure high peak currents but you should
