For a fully charged 12V lead acid battery at rest, a voltage around 12.6V to 12.8V indicates full capacity. 11.8V is considered fully discharged for most lead acid batteries. The voltage will vary under load and charge. How Can I Tell if My Lead Acid Battery Is Bad?
Charts for different lead acid battery voltages follow the same format. Just multiply the voltages by 2 for 24V or 4 for 48V batteries. The only way to get an accurate reading of a lead acid battery's state of charge from voltage is to measure its open circuit voltage.
Higher lead acid battery voltages indicate higher states of charge. For instance, 12.6V means a 12V battery is fully charged, while 12.0V means it's around 50% capacity. Temperature affects voltage, too. Cold temperatures increase the voltage while hot temps decrease it. The charts here assume room temperature.
The optimal charging voltage for 48V flooded lead acid batteries is typically around 58V to 62V at the start of charging. Sealed batteries may need slightly higher voltages. Refer to the battery specifications. How Can I Revive a Dead Lead Acid Battery?
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.
There are a few different methods used to charge lead acid batteries: Constant Voltage – Charges at a set voltage level, typically around 2.45V per cell. The current drops off towards the end as the battery reaches full capacity. Constant Current – Charges at a set current level. Reliable but requires monitoring voltage to prevent overcharging.
