The nominal voltage of lithium-ion is 3.60V/cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher. This offers a marketing.
Just like any other battery type, lead acid batteries have different voltages at various stages of charge. For instance, a 12V sealed lead acid battery has a voltage of 12.89V at 100% charge, while 11.63V indicates it is at 0% charge.
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?
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?
For instance, a 12V sealed lead acid battery has a voltage of 12.89V at 100% charge, while 11.63V indicates it is at 0% charge. The good news is that you can refer to a lead acid battery voltage chart to find the specific battery voltage (6V, 12V, 24V, 48V, etc.) corresponding to the state of charge (SOC).
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.
To read a Lead Acid Battery Voltage Chart, locate your battery type on the chart. Check the voltage measurement, which you can obtain using a multimeter. Compare this voltage to the values in the chart. For example, a fully charged battery typically shows around 12.6 volts.
