Float Voltage: What It Is for Lead Acid Batteries and Charging Recommendations
Float voltage for a lead acid battery maintains a fully charged state. It is typically between 2.25V and 2.30V per cell at 25°C (77°F). For a 12V system, the float voltage is about 13.5V to 13.8V. This voltage helps counter self-discharge while preventing battery damage. Charging recommendations for lead acid batteries include setting the float … Read more
