How Long Can A Lead Acid Battery Be Stored. The way the power capability is measured is in CsA C is the Amp-hour capacity divided by 1 hour. A sealed lead-acid battery can be stored for up to 2 years.
Sealed Lead Acid Battery. Lead sulfate is a soft material which can is reconverted back into lead and sulfuric acid provided the discharged battery is immediately connected to a battery chargerIf a lead acid battery is not immediately recharged the lead sulfate will begin to form hard crystals which can not be reconverted by a standard fixed voltage. Most important is the storage temperature.
There are exceptions such as the Monobloc batteries that can have up to 300 cycles.
Before diving into the topic of battery storage note that lead-acid batteries have low internal resistance and special alloys in the electrodes which assures a low self-discharge rate and consequently a long shelf life. Store It and Forget It Batteries are not items you can put away for the winter and forget about. Recharge lead acid and lithium-ion batteries periodically. The cycle life of lead acid batteries is lower than that of other rechargeables.
