Do lead-acid batteries deteriorate during service life?
In ideal theory, the physical and electrochemical variables of lead–acid batteries continue to increase (decrease) in the direction of deterioration during service life operation. However, battery variables fluctuate during aging tests and field operations.
How do you prevent sulfation in a lead acid battery?
Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.
Are lead-acid batteries aging?
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt, and elsewhere, . The present paper is an up-date, summarizing the present understanding.

Do lead acid batteries lose water?
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
