By using a desulfator, you can dissolve the sulfur accumulating in your battery. During this process, current passes through the sulfate buildup. The build up then drops into the battery acid and dissolves. Battery damage does not occur during this process. Different ways to desulfate lead-acid batteries
The desulfator will break down the lead sulfate crystals that have formed on the battery plates, allowing the battery to hold a charge again. Maintaining Reconditioned Batteries Once you have reconditioned your lead acid battery, it is important to maintain it properly to ensure its longevity and optimal performance.

This is when your lead-acid battery is discharged below 50%. When this happens, small pieces of the lead plates can actually break off and sink into the electrolyte solution. Then, there is less material available to cause …
Lead-acid battery State of Charge (SoC) Vs. Voltage (V). ... Ah battery delivering 5 A is said to be discharging at a C/20 rate where C is the Ah capacity, and 20 is the depletion time in hours. However, the same battery may not be capable of delivering 100 Ah at C/5 (20 A for 5 hours). In fact, rapid discharge results in a lower Ah capacity.
Lead acid batteries, on the other hand, produce a substantial amount of heat when charging. Because of this, they require a "cool down" period afterward. A typical charge and use cycle for a lead acid battery is 8 hours of …
In ideal circumstances an SLA battery should never be discharged by more than 50%, for a maximum life span no more than 30% (to a 70% state of charge). If it''s completely …

The lead-acid battery has retained a market share in applications where newer battery chemistries would either be too expensive. Lead-acid does not lend itself to fast charging. Typical charge time is 8 to 16 hours. A periodic fully saturated charge is essential to prevent sulfation and the battery must always be stored in a charged state.
If that rate is more than the battery''s natural absorption rate at full charge, the electrolyte will begin to break down and boil away. Many a rider has stored a bike all winter on a trickle charger only to find the battery virtually …
A well-maintained lead acid battery has a lifespan of 1000 to 1500 charging cycles. Important point to note here is that even if you charge a lead-acid battery for a short period, say 15 minutes, that counts as one charging cycle. This further reduces the lifespan of a lead-acid battery if you do not carefully charge it to 100% every time.
