It is necessary when handling an AGM battery to observe some particular points pertaining to battery changing and installation location.
Charge
WARNING:
Do not charge the AGM battery with ≥ 14.8 V. Do not use rapid-charging programs!
When charging removed batteries (so-called stand-alone batteries), do not exceed the maximum charging voltage of 14.8 V at room temperature. Also, for charging via the external start connection point, the maximum charging voltage of 14.8 V at room temperature must not be exceeded. The battery can be damaged even if the AGM battery is only briefly charged with a charging voltage higher than 14.8 V. A charging voltage of more than 14.8 V is usually used in quick-charging routines.
