Sir i need your help regarding batteries. i have new battery in my store since 1997 almost 5 years old with a 12 Volt 150 Ah when i check the battery some battery shows 5.6 volt and some are shoinfg 3.5 volt. sir please tell me if i charged these batteries it will work or not or what is the life of battery. these are lead acid battery .
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
To prolong the life of a lead-acid battery, it is essential to follow proper charging and discharging procedures. Overcharging or undercharging can significantly reduce the lifespan of a battery. It is also important to avoid deep discharging the battery as a deep cycle can damage the battery’s plates.
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let’s suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
Lastly, the temperature also plays a significant role in the lifespan of a lead-acid battery. High temperatures can accelerate the aging process of the battery, while low temperatures can reduce the battery’s capacity. Therefore, it is important to store the battery in a cool and dry place.
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.

The addition of 3–6% calcium makes battery plates more resistant to corrosion, overcharging, gassing, water usage, and self-discharge. All of these processes contribute to shortening the battery life. Lead–acid batteries with electrodes modified by the addition of Ca also provide for higher currents or Cold Cranking Amps. These batteries ...
