Customer ServiceWhen the cell is fully charged, the specific gravity of the electrolyte will be approximately 1.21. When the cell is fully discharged its value falls to 1.17. Cells are considered to be fully charged once three successive hourly readings of cell voltage and electrolyte gravity are found to be constant. However, the minimum total ampere- hours
Customer ServiceThe 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. The most important lesson here is this:
Customer ServiceCharge your battery in a well-ventilated location. Select a location like a garage or large shed. Open a door or window if you can. Good ventilation is important because, during the charging process, a mixture of gases builds up in your battery, and if the battery is overcharged or shorts out, these gases may vent out of the battery.
Customer ServiceHow can I revive my sealed lead acid battery that won''t hold a charge? If your sealed lead acid battery won''t hold a charge, there are a few things you can try to revive it. First, make sure the battery is fully charged. If it still won''t hold a charge, try using a desulfator or a pulse charger to remove any sulfation buildup on the

Customer ServiceWhile NiCd loses approximately 40 percent of their stored energy in three months, lead acid self-discharges the same amount in one year. The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in subzero conditions. According to RWTH, Aachen, Germany (2018), the cost of the flooded lead acid is about $150 per kWh, one of the lowest in
Customer ServiceThe first curve from the left shows what happens if a lead–acid battery is discharged fully each cycle or the depth of discharge is 100%. The maximum cycle life that a battery can reach before the capacity drops to 60% is around 200. The curve for 50% depth of discharge shows a similar trend with the maximum number of cycles between 500 and 600.

Customer ServiceTest show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
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.
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every six months to prevent the voltage from dropping below 2.10V/ cell. With AGM, these requirements can be somewhat relaxed.
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge.

We’ve put together a list of all the dos and don’ts to bear in mind when charging and using lead-acid batteries. Apply a saturated charge to prevent sulfation taking place. With this type of battery, you can keep the battery on charge as long as you have the correct float voltage.
As with all other batteries, make sure that they stay cool and don’t overheat during charging. Sealed lead-acid batteries can ensure high peak currents but you should avoid full discharges all the way to zero. The best recommendation is to charge after every use to ensure that a full discharge doesn’t happen accidently.
