According to the BCI (Battery Council International (BCI) is a not-for-profit trade association formed to promote the interests of the international battery industry) AGM and flooded cells charge differently . For AGM batteries it is recommended to use a charger, current limited to 20% or 0.2C of the batteries capacity at a charging voltage of between 14.6 – 14.8V DC. For flooded lead acid batteries, the typical charging voltage is between 2.15 volts per cell (12.9 volts for a 12V 6 cell battery) and 2.35 volts per cell (14.1 volts for a 12V 6 cell battery). These voltages are appropriate to apply to a fully charged battery without overcharging or damage.
Some of the better quality maintainers have specific settings for AGM or flooded cell batteries.
