Being 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?
The highest voltage 48V lead battery can achieve is 50.92V at 100% charge. The lowest voltage for a 48V lead battery is 45.44V at 0% charge; this is more than a 5V difference between a full and empty lead-acid battery. With these 4 voltage charts, you should now have full insight into the lead-acid battery state of charge at different voltages.
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.
Temperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
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.
Lead acid batteries are generally charged till the voltage reaches 13.8V at 25ºC (more at colder, less at hotter temperatures) The rate of charge is generally limited at about 1/10 the Ah rating of the battery.
