The capacity of all batteries changes with temperature, and for lead acid batteries, more change is found, particularly at the lower temperatures. The battery therefore has to be sized to provide the required standby time even under the worst applicable temperature conditions.
For international use, the typical lead acid battery consists of 55 cells having a battery voltage range of 96–128 V, resulting in a required equipment voltage range of 91–128 V.
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 ideal charging voltage for a sealed lead acid battery is around 13.6 to 13.8 volts. This voltage range promotes optimal electrolyte absorption and prevents excessive gassing. It is essential to follow the manufacturer’s guidelines to avoid damaging the battery or reducing its lifespan.
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.
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.
