View moreBeing familiar with a lead acid battery voltage chart can help you to understand the state of your battery at a glance. What voltage should a fully charged lead acid battery be? A fully charged lead-acid battery should measure at about 12.6 volts.
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
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 minimum open circuit voltage of a 12V flooded lead acid battery is around 12.1 volts, assuming 50% max depth of discharge. How much can you discharge a lead acid battery?
24V sealed lead acid batteries are fully charged at around 25.77 volts and fully discharged at around 24.45 volts (assuming 50% max depth of discharge). 24V flooded lead acid batteries are fully charged at around 25.29 volts and fully discharged at around 24.14 volts (assuming 50% max depth of discharge).
Going back to the chart above, it shows that a 12V sealed lead acid battery is in its fully charged state at 12.89 volts and that it is in a fully discharged state at 12.23 volts (assuming 50% max DOD). This shows a 0.66 volt difference between 100% and 0% charge.
