Notes for Service department

It is necessary when handling an AGM battery to observe some particular points pertaining to battery changing and installation location.

Charging

WARNING: Do not charge the AGM battery with ≥ 15.2 V. Do not use rapid-charging programs!

When charging removed batteries (so-called stand - alone batteries), do not exceed the maximum charging voltage of 15.2 V at room temperature. Also, for charging via positive battery connection point the maximum charging voltage of 15.2 volt at room temperature must not be exceeded. The batter can be damaged even with short charging of the AGM battery with a charging voltage higher than 15.2 volts. A charging voltage of more than 15.2 V is usually used in quick-charging routines.

Installation location

WARNING: Do not install the AGM battery in the engine compartment.

The AGM battery must not be installed in the engine compartment on account of the high spatial temperature differences, otherwise its service life will be significantly shortened.

Housing

WARNING: Do not open AGM batteries.

On no account may AGM batteries be opened, as the ingress of oxygen from the atmosphere would cause the battery to lose its chemical balance, rendering it unserviceable.

Battery renewal

On principle any conventional lead-calcium battery can be replaced with an AGM battery. No changes result for the vehicle electrical system by using an AGM battery.

NOTE: AGM batteries are especially recommended for "problem customers".

"Problem customers" have a very high energy throughput through the battery. This high energy throughput is caused by stationary loads/consumers (TV, independent heating, etc.) and a bad use profile for the battery ("chauffeur operation", short-distance driving, "stop - and - go"). The use of an AGM battery is recommended for these problem customers.
