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.
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?
Then we can give the regulated voltage to the battery to charge it. Think if you have only DC voltage and charge the lead acid battery, we can do it by giving that DC voltage to a DC-DC voltage regulator and some extra circuitry before giving to the lead acid battery. Car battery is also a lead acid battery.
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. This means the battery must be disconnected from all loads and chargers and allowed to rest for several hours until its voltage stabilizes.

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.
