Recharging the AGM battery
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
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 IU or WU 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.
