Proper maintenance of sealed lead-acid batteries involves regular charging and discharging cycles, keeping the battery clean and dry, and avoiding exposure to extreme temperatures. It is also important to check the battery’s voltage regularly and to replace it when necessary. What is the charging and discharging process of lead acid battery?
With correct and accurate cell voltage control all gasses produced during the charge Guide to charging Sealed Lead Acid batteriescycle will be re-combined completely into the negative plates and returned to water in the electrolyte.
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 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.
Seek out new charger technology: Older lead acid battery chargers require careful monitoring to avoid “over-charging.” But new charger technology allows the batteries and charger to be plugged in over a weekend or longer. The charger will shut off once the full charge on batteries is reached.
You can extend the life of your sealed lead acid battery if you are careful about charging it. More batteries are damaged by bad charging techniques than from all other causes. Check the manufacturer’s recommendation for charging and use the proper charger for the battery.
