Part: Battery

To replace the battery in a Kia Optima, open the bonnet to access the components inside the engine bay. Unscrew the screws securing the air duct, which must be removed from its housing to access the battery underneath. Now disconnect the power cables connected to the device, allowing you to unscrew the battery retaining bolts. This way, the battery can be extracted from its housing and replaced with a new spare part. After the replacement, refit all the components removed earlier.
