[AGM Battery for ISG System]

AGM battery is used for especially heavy load on the vehicle network depending on equipment and requirements. AGM stands for Absorbent Glass Material Battery, which is absorbent glass fibre fleece. AGM batteries are fitted to models with high electrical loads or for consumer with high energy demand.

The constantly increasing energy demand of modern vehicle electrical systems calls for ever more powerful battery solutions.

The power consumption is considerably high even when the vehicle is partked.

The somewhat higher price compared with a battery of similar size is fully balanced by the following benefits:

-

Significantly longer service life

-

Increased starting reliability at low temperatures

-

100% free from maintenance

-

Low risk in the event of an accident (reduced risk to the environment)

Recharging the AGM battery

The battery can be charged by using a battery charger with a constant charging voltage of 14.8 V.

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

Only chargers with voltage clamping (IU or WU curve) or chargers with IUoU curve capable of trickle charge can be used.

IU or WU charging technique

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

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

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

10% of capacity is recommended as charging current (e.g. 60 Ah : 10 = 6.0 A charging current).

caution

Do not charge an AGM battery with voltage greater than 15.2 V. Do not quick charge the AGM battery.

note

If the battery is charged directly at the battery terminals on vehicles with battery sensor, misinterpretations of battery condition may occur, and under certain circumstances, unwanted 'Check Control' message or faulty memory can be prompted.

When recharging is finished, let the battery stand for over 10 hours at normal temperature for battery stabilization.
