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.
Many organizations have established standards that address lead-acid battery safety, performance, testing, and maintenance. Standards are norms or requirements that establish a basis for the common understanding and judgment of materials, products, and processes.
Characteristic of the open (or vented) lead acid battery is that the small amounts of hydrogen and oxygen produced at the electrodes during battery operation can be vented to the atmosphere through small holes at the top of the battery.
Lead-acid batteries, which are waiting for installation, should be stored in a dry and cool atmosphere. The long time storage at high temperature will have a detrimental effect on life as the corrosion of the lead electrodes is accelerated at elevated temperatures.
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%.
For a high antimony lead-acid battery, a 130-150 Ah capacity may be required to deliver 100 Ah over a 30 day period to the load whereas for a lead-calcium or pure lead battery, only 102-104 Ah would be needed. This trade off must be considered

Tech Note | Battery Room Ventilation Requirements
Lead-Acid (LA) and Nickel Cadmium (NiCd) batteries vent hydrogen and oxygen when they are being charged. In the case of Valve-Regulated designs, the hydrogen is recombined with the oxygen within the battery back into water unless the gassing volume/pressure exceeds the opening setting of the pressure relief valve. Hence the name Valve-Regulated.
