GV70 Internal Combustion 12 volt battery failing

[Gib]

My 3.5 year old 2022 GV70 has had trouble with the auto stop function failing (past 6 months) because the battery did not reach the minimum charge level for it to work. Now if it does work, when the car restarts the screen goes black for a few seconds while the engine starts. So I think the 12 volt battery is near its end of life.

Genesis may have cut corners on the alternator output because I think it should charge the battery quicker than it does. I read that running the car at idle for 60 minutes to charge the battery is a solution...that makes no sense to me. Having to put a trickle charger on it makes more sense but I don't think a "luxury car" should require that.

I am probably going to bite the bullet and get a new battery. I understand that trying to find a battery that matches the Genesis OEM battery is impossible due to the positive terminal location and the fact that the battery is vented to the outside of the car because the battery is in the trunk area.

I hope that the Hyundai dealer will have the correct battery. This dealership is only 7 miles away versus the closest Genesis dealer that is 30 miles further.

Any suggestions or guidance will be appreciate. Thanks.

Batteries typically last 3 to 5 years depending on conditions.
As for needing a trickle charger, that depends on how often you drive, conditions, etc. Cars today use a lot more than in the past, often just waiting for your command to remote start or unlock.

Thread 'GV70 Battery Replacement?'

Mar 9, 2024

Has anyone replaced the battery of their GV70 with something other than the very expensive and difficult-to-acquire O.E.M. factory battery?
Will a H8 AGM fit? I have been led to believe the issue of finding a non-O.E.M. battery relates to the reverse polarity of the O.E.M. battery. True?

Looking forward to seeing if the new battery worked. Thx for post.
