The nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge.
Discharge characteristics: Generally quite curved, particularly at higher discharge rate. Best performance with intermittent discharge. The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte.
While on float charge, lead acid measures about 2.25V/cell, higher during normal charge. In consumer applications, NiCd and NiMH are rated at 1.20V/cell; industrial, aviation and military batteries adhere to the original 1.25V.

For a lead-acid battery, the value above the OCV is approximately 0.12 volts. This “adder” voltage will vary very slightly (about +/- 0.02V) for different plate additives and construction, but it is a very good rule of thumb. Although the following shows some example calculations, the manufacturer’s recommended float voltage should always be used.
