How long does a Kia Optima Hybrid Battery Last?
Kia Optima batteries usually last between 3-5 years, but this is variable depending on your driving habits, the weather conditions, and the type of battery.
You can extend the life of your Kia Optima Hybrid and PHEV battery by keeping your vehicle stored indoors and away from large swings in temperature.
12V Battery
The Kia Optima 12V battery powers the low-voltage electrical systems within the car, such as the headlights, dash lights, starter motor and more.
The battery here is special for the hybrid, made using a sealed maintenance-free gel cell 12V battery. This is because it is in the trunk and share’s air with the passengers. Vapors released from a standard lead-acid battery are not good for you.
Also, the 12V battery is an auxiliary battery in the hybrid, with the main power supply coming from a DC-DC converter up front. This is so that the Aux 12V battery can be left in low states of charge for extended periods of time, which standard lead acid batteries do not handle as well especially if freezing temperatures are involved.
The best place to find a replacement is your Kia Dealership. Others have had success with an Optima 12V.

Kia Optima Hybrid 12V Battery Testing and Repair
Battery testers are an inexpensive way to save yourself time in repairing your Kia Optima Hybrid. A healthy 12V battery will read between 12.6 and 12.8 volts when tested. Anything lower, and you may want to consider replacing your batteries or checking the battery fluid levels.
