WARNING: This page is about a different variant/trim than selected.

Check the battery condition

The battery condition cannot be determined solely on the basis of the battery charge state. If there is a suspicion of a damaged battery, check the battery condition whit battery tester and investigate the cause by means of the test module. With a low battery charge state, recharge the battery.

Recharging the AGM battery

The battery may be charged using the battery chargers at a constant charge voltage of 14.8V.

If possible, the battery temperature during charging should be between 20°C (68°F) and 30°C (86°F).

Only chargers with voltage clamping (IU or WU curve) may be used or chargers with IUoU curve which have a trickle.

IU or WU charging technique

Optimized charging voltage for IU or WU: 14.7V (at 20 - 30°C (68 - 86°F)) about 24 hours

Min. charging voltage at 20°C (68°F): 14.4V

Max. charging voltage at 20°C (68°F): 14.8V

10% of capacity is recommended as charging current (e.g. 60Ah: 10 = 6, 0A charging current).

WARNING: Do not charge the AGM battery with>15.2V. No quick-charging routines.
