This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load.
The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.
This wear-down characteristic applies to all batteries in various degrees. Depending on the depth of discharge, lead acid for deep-cycle applications provides 200 to 300 discharge/charge cycles.
Charging a lead acid battery is simple, but the correct voltage limits must be observed. Choosing a low voltage limit shelters the battery, but this produces poor performance and causes a buildup of sulfation on the negative plate. A high voltage limit improves performance but forms grid corrosion on the positive plate.
Discharging of a lead acid battery is again involved with chemical reactions. The sulfuric acid is in the diluted form with typically 3:1 ratio with water and sulfuric acid. When the loads are connected across the plates, the sulfuric acid again breaks into positive ions 2H+ and negative ions SO 4.
If we break the name Lead Acid battery we will get Lead, Acid, and Battery. Lead is a chemical element (symbol is Pb and the atomic number is 82). It is a soft and malleable element. We know what Acid is; it can donate a proton or accept an electron pair when it is reacting.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load.

Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions ...
The charging of a lead-acid battery occurs in distinct phases, each with specific characteristics and reactions. Bulk Charge Phase; Absorption Charge Phase; Float Charge Phase; These phases reflect the various states of charge in a lead-acid battery, which can influence battery chemistry, performance, and longevity.
Lead acid does not lend itself to fast charging and with most types, a full charge takes 14–16 hours. The battery must always be stored at full state-of-charge. Low charge causes sulfation, a condition that robs the battery of performance. Adding carbon on the negative electrode reduces this problem but this lowers the specific energy.
