How to maintain a sealed lead-acid (SLA) battery system
Lead-acid batteries have been supplying power since the 1850s. The Sealed 12v Battery system powers lighting equipment, wheelchairs, boats, lawnmowers, portable tools, golf carts, ATVs, scooters, and motorcycles. When not in use, you should store fully charged SLA batteries in a cool environment to prevent loss of power. Unlike non-SLA batteries, sealed batteries require little maintenance, refilling, or other forms of maintenance, but many people take certain precautions to extend the life of these batteries.
Protective maintenance improves safety and reliability
Most battery manufacturers recommend replacing inefficient SLA batteries. These batteries will work better when fully charged, so they should be charged when the battery level is below 50% or after 30 days of storage.
When the power is less than 40% of capacity, the electrolyte will freeze in the lead-acid battery.
Battery delamination occurs when water and internal liquid are converted into lead sulfate and separated from the mixture and settled to the bottom of the battery.
Delamination reduces battery power, causing the battery to overheat, water evaporates, corrode, and eventually fail.
Regular recharging of SLA batteries prevents delamination, freezing and degrading battery performance.
