The factor limiting the charging speed of lead–acid batteries is often the dissolution of the sulphate crystals in the negative active mass. This greater resistance means that the cell reaches the constant-voltage stage at a lower state of charge. As such, the cell needs longer in the constant-voltage stage to reach a full state of charge.
The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material. According to the 2010 BCI Failure Modes Study, plate/grid-related breakdown has increased from 30 percent 5 years ago to 39 percent today.
If at all possible, operate at moderate temperature and avoid deep discharges; charge as often as you can (See BU-403: Charging Lead Acid) The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material.
Such batteries may achieve routinely 1500 cycles, to a depth-of-discharge of 80 % at C /5. With valve-regulated lead–acid batteries, one obtains up to 800 cycles. Standard SLI batteries, on the other hand, will generally not even reach 100 cycles of this type. 4. Irreversible formation of lead sulfate in the active mass (crystallization, sulfation)
Most of the internal resistance increase is due to the sulphation of the negative active material. The factor limiting the charging speed of lead–acid batteries is often the dissolution of the sulphate crystals in the negative active mass. This greater resistance means that the cell reaches the constant-voltage stage at a lower state of charge.
dCNT changes the nature of lead acid batteries. Increased charge acceptance and alteration of the electrode surface chemistry require additional attention to side-reaction management. A battery containing dCNT charges faster than a conventional battery, obviating the need for elongated recharge periods, especially on float.
Investigations into the Charge Times of Lead–Acid Cells under
Charging times in lead–acid cells and batteries can be variable, and when used in PSOC operation, the manufacturer''s recommended charge times for single-cycle use are not necessarily applicable. Knowing how long charging will take and what the variability in time required is allows for better planning of operations and algorithm creation ...

Five ways to extend the life of your lead acid battery. Part I
Sulphation: Lead and lead-dioxide react with sulphuric acid to form lead sulphate – small crystals which easily reforms back to lead, lead-dioxide and sulphuric acid. After time, some lead sulphate does not revert, but forms a stable crystalline coating which no longer dissolves on recharging. Sulphation can be reduced if a battery is fully re-charged after a …

Capacity reduction (degradation) of lead-acid battery over time is a regular occurrence. This is because a battery is typically designed to be cycled between 20 and 80 % SOC. An 80 % state of charge indicates that the remainder, 20 % are sulphates. If these sulphates are not converted into active material by 100 % charge, they become hard and ...
