Kia Forte: AGM Battery Adjustment
Second generation YD (2014-2018) / Kia Forte TD 2014-2018 Service Manual / Engine Control / Fuel System / ISG (Idle Stop & Go) System / AGM Battery Adjustment
| Battery charging |
In general, vehicle battery charging system has three forms.
| 1. |
Constant current charge: The battery voltage gradually rises by
charging with setting a constant current. If charging current and time
are not managed correctly, the battery is over-charged, therefore charging
should be stopped after confirming the completion of charging.
|
| 2. |
Constant voltage charge: The battery charge current is gradually
reduced by charging with setting a constant voltage.
|
| 3. |
Constant current-Constant voltage charge: Charging with constant
current and voltage to protect the battery damage
|
[AGM battery charging]
AGM battery should be charged with constant voltage or constant current-constant
voltage in order to minimize performance degradation due to the charging.
If charging the battery with constant current, overcharging may occur.
It can cause damage to the internal battery and will give an adverse effect
on battery life.
Do not charge with more than 14.8V or quick charge mode.
|
[Constant voltage charge conditions]
Charging voltage / time:
14.7V [68°F ~ 86°F (20°C ~ 30°C)] / approximately 24 hours
The minimum charge voltage:
14.4V [68°F ~ 86°F (20°C ~ 30°C)]
The maximum charging voltage:
14.8V [68°F ~ 86°F (20°C ~ 30°C)]
|
Battery temperature should be maintained at about 68°F ~ 86°F
(20°C ~ 30°C) during charging of the battery.
|
If the battery is charged directly at the battery terminals on
vehicles with battery sensor, misinterpretations of battery condition
and under certain circumstances also unwanted Check Control messages
or fault memory entire can occur.
After recharging finished, let the battery stand for over 10 hours
with normal temperature for battery stabilization.
