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.
As the rate of discharge increases, the battery's available capacity decreases, approximately according to Peukert's law. Manufacturers specify the capacity of a battery at a specified discharge rate.
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.
CONCLUSIONS The purpose of this work was to revisit Peukert’s equation and examine its validity with modern lead acid and lithium batteries. Experimental data suggests that Peukert’s exponent for individual lead acid batteries is not constant but it is a function of battery capacity and discharge current.
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.
