A lower voltage reading on the Lead Acid Battery Voltage Chart generally suggests a lower state of charge in the battery. It indicates that the battery has less available energy and may require charging to maintain its optimal performance. Can the Lead Acid Battery Voltage Chart be used for all lead acid batteries?
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.
If the float voltage is set to 2.30V/cell at 25°C (77°F), the voltage should read 2.27V/cell at 35°C (95°F). Going colder, the voltage should be 2.33V/cell at 15°C (59°F). These 10°C adjustments represent 30mV change. Table 3 indicates the optimal peak voltage at various temperatures when charging lead acid batteries.
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.
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?
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 …
