What setting do you use to charge AGM battery?

To charge an AGM (Absorbent Glass Mat) battery, it is recommended to use a dedicated AGM battery charger or a smart charger that has a setting specifically for AGM batteries. The charging voltage should typically be set between 14.4 to 14.7 volts, with a maximum charging current that does not exceed 0.2C (20% of the battery's capacity). It's important to ensure the charger has a temperature compensation feature to adjust the voltage based on the battery temperature, promoting optimal charging and preventing damage. Always follow the manufacturer's guidelines for the specific AGM battery being charged.
