Wet Cell Battery Charging: What Voltage Is Required and Essential Basics
To recharge a wet lead-acid battery, use an absorption voltage of 14.25 V for 12 V systems and 28.5 V for 24 V systems. The float voltage should be 13.25 V for 12 V systems and 26.5 V for 24 V systems. These values are valid at a temperature of 25 °C for efficient charging. … Read more
