One common reason why a sealed lead acid battery might not hold a charge is due to a lack of maintenance. If the battery is not charged properly, or is left unused for long periods of time, it can become depleted and unable to hold a charge. Additionally, if the battery is overcharged, it can become damaged and unable to hold a charge as well.
When a sealed lead acid battery is charged, electrical energy is converted into chemical energy, which is stored in the battery. The lead plates and lead oxide plates react with the electrolyte to form lead sulfate and water. When the battery is discharged, the lead sulfate and water react to form lead, lead oxide, and sulfuric acid.
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
Can I recharge a completely dead sealed lead acid battery? Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done.
The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging. Although it can be left idle for some time in charged condition.
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.
