Learn MoreHigher 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.
12V flooded lead acid batteries are fully charged at around 12.64 volts and fully discharged at around 12.07 volts (assuming 50% max depth of discharge). 24V lead acid batteries are another common option for solar power systems. Working with higher voltages helps keep amperage low, saving you money on wiring and equipment.
As a lead acid battery discharges, the voltage decreases linearly. For example, a 12V battery may provide 12.6V when fully charged. After discharging halfway, the voltage will drop to around 12.3V. The rate of discharge impacts the voltage. Faster discharge rates result in lower voltages for a given state of charge.
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?
