6 FAQs about [The lead-acid battery can be disconnected if it is not fully charged]
Why does a lead-acid battery lose power?
A lead-acid battery acts as a store of power because of the reaction between the lead plates and the electrolyte. The reason that both sulfation and acid stratification cause batteries to lose power and the ability to accept charge is because they both reduce the contact between the lead plates and the active electrolyte.

How do lead-acid batteries work?
Lead-acid batteries work by converting chemical energy into electrical energy. The battery consists of two lead plates, one coated with lead dioxide and the other coated with lead. The plates are immersed in an electrolyte solution made of sulfuric acid and water.
Do all lead-acid batteries suffer from sulfation?
All lead-acid batteries suffer from sulfation. It’s just chemistry. Lead-acid batteries contain lead plates and a free-flowing solution of sulphuric acid. One of the inevitable byproducts of the plates and acid coming into contact is that lead sulfate will accumulate on the lead plates of the battery.
How often should a lead acid battery be recharged?
Sealed lead acid batteries need to be kept above 70% State of Charge (SoC) during storage. If you’re storing your batteries at the ideal temperature and humidity levels, then a general rule of thumb would be to recharge the batteries every six months. However, if you’re unsure, you can check the voltage to determine if a recharge is necessary.
