As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery’s electrolyte and the chemistry of the plates.
Contamination in sealed and VRLA batteries usually originates from the factory when the battery is being produced. In flooded lead-acid batteries, contamination can result from accumulated dirt on top of the battery and when the battery is being watered. Watering the battery with tap water has a serious consequence on the battery.
Vibration Vibration is another major reason for battery failure. Excessive vibration can cause the battery’s internal plates to shift and become damaged, leading to a breakdown in the battery’s structure and causing short circuits within the battery. Vibration also accelerates corrosion, which leads to premature failure.
A lead-acid battery is designed to last a finite period. It cannot last forever. When the battery is wet and is undergoing the cycle of charging and discharging, it will last about 3-5 years though depending on the usage and maintenance, the battery can last up to 7years.
Apart from occasional field surveys of automotive batteries in the U.S.A., comprehensive failure analyses of units removed from service are rarely published. In general, the information is kept proprietary, or appears as a post mortem report that is subsidiary to some other topic of interest.
Why Your Sealed Lead Acid Battery Won''t Hold a Charge
A sealed lead acid battery consists of six cells, each containing a lead plate and a lead oxide plate submerged in an electrolyte solution of sulfuric acid and water. The six cells are connected in series, with each cell producing a voltage of 2 volts. This means that a fully charged battery has a voltage of 12 volts. The battery is sealed to prevent the electrolyte from leaking. …

Over discharge leads to hydration. Hydration occurs in a lead-acid battery that is over discharged and not promptly recharged. Hydration results when the lead and lead compounds of the plates dissolve in the water of a discharged cell and form lead hydrate, which is deposited on the separators. When the cell is recharged, multiple internal ...
