Battery Handling and Storage

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.

Battery

Batteries should be stored in cool, dry (27 degrees Celsius) places and out of direct sunlight.
MF batteries are tightly sealed to prevent acid leakage.
However, tilting the battery to an angle of 45 degrees can cause acid to leak through the vents on the sides. Therefore, batteries should always be stored in their upright positions. Do not place any solution or objects (i.e. conductors) on top of the battery.
It is extremely dangerous to use tools, such as hammers, on the battery terminals when connecting cables to the mounted battery.

Battery installed in vehicle

When storing the vehicle for long periods of time, make sure to remove the battery fuse from the junction box to prevent natural discharging.
In case of the vehicle stored with the battery fuse connected, run the engine for battery charging within one month from the start of vehicle storage.
In case of the vehicle stored with the battery fuse disconnected, run the engine for battery charging within three months from the start of vehicle storage.

NOTE:

After reconnecting or recharging a discharged battery, the ESP OFF indicator may illuminate.
In this case, turn the handle half way to the left and right while the ignition switch is in the ON position.
Then, restart the engine after the ignition is OFF.
The ESP OFF indicator may turn OFF.
If the ESP OFF indicator does not turn OFF, have the system checked by referring to DTC. (Refer to the ANTI-LOCK BRAKE SYSTEM/ELECTRONIC STABILITY CONTROL SYSTEM DTCS )
