Scope: This recommended practice provides design considerations and procedures for storage, location, mounting, ventilation, assembly, and maintenance of lead-acid storage batteries for photovoltaic power systems. Safety precautions and instrumentation considerations are also included.
The steps used in charging of an open or vented lead acid battery are named: main charge, used for charging the battery up to a voltage level when gassing starts and the voltage rises. (The voltage limit is 2.39 V at 25°C and 2.33 V at 40°C). top-up charge, to reach the 100 % state of charge from a level of 90 - 95 %.
In designing a battery for a particular photovoltaic system, the number of battery cells needed in series can be determined by dividing the lowest specified system voltage by the final voltage of the cell selected when discharged at the required system rate for that cell.
Purpose: This recommended practice is meant to assist lead-acid battery users to properly store, install, and maintain lead-acid batteries used in residential, commercial, and industrial photovoltaic systems.
The theoretical voltage of a lead-acid battery cell depends on the chemical reactions inside it. Under standard conditions it is 1.93 V (or 11.6V for a 6-cell monoblock battery). In practice 2.0 V is used as a reference value for a single cell. This is called the nominal voltage. According to this a 6-cell battery is referred to as a 12 V battery.
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.

Connecting lead acid batteries in series involves connecting the positive terminal of one battery to the negative terminal of another. This increases the overall voltage while keeping the capacity (ampere-hours) constant. For instance, if you connect two 12V lead acid batteries in series, you will get a 24V battery system.
