12V Battery Replacement ?

Mon Aug 05, 2019 5:22 pm

I have a 2015 Soul EV (man'f. Oct. '14) with 15K+ miles. I'm concerned about the life of the 12V 45AH Aux Battery (sealed).
Should I worry about remaining life?
Looking for any suggestions on the remaining life and where to buy a replacement online.
Thx,
Ed

I would not buy a replacement online, too many problems with shipping both weight and regulations about shipping battery acid.

I bought my replacement from a local store that specializes in batteries, but any normal auto parts store should be able to help.

Thx for the info. I would like to know the specifics of your new battery ; brand, p/n.
Also, did you wait until the old batt. failed or what ?
Finally, any surprise resettings after the new batt. installed ?
Thx for your help.

The problem with an EV is that there isn't any indication that the 12V battery is about to fail. On an ICE car you will hear it get slower on the starter motor when the 12V battery is getting weak. On an EV the 12V battery only needs to have enough power to turn on the main relay and then the car is powered from the DC-DC converter. Mine just failed to turn on one day with all kinds of weird dash indications (I don't know exactly what, it was my wife who was trying to start it).

I went to a local Total Battery outlet and exchanged the old battery for a new one - I don't recall the exact part number but that would be specific to Total Battery and if you are going to another auto parts store then it will be different.

I don't remember anything in particular resetting, it was last winter so I may be mistaken. I think I lost the radio stations but that may have been it - I don't recall.

Thx for the useful info on battery lack-of-fail-warning, a surprise for me.

I checked the owner's manual and only says it is a "maintenance-free" battery (pg.7-34).
Does recommend to "inspect battery condition" every 7,500 mi/6-mo. Probably means just exterior ?
Also, calls out different recharging rates, depending on how it got discharged, AND, to remove battery from car when recharging.
Finally, does describe what to Reset after battery has been disconnected: auto-windows, trip computer, climate, and audio.

I guess i'll get a new battery, after almost 5-years (58-mo.) from date of manuf .

Mechanics will have a battery load testing tool that gives a readout of the 12V battery's state. In the U.S. AutoZone and in Canada Partsource will test the battery for free.
I would get a battery test done rather than just buying a new one based on age.

Does anyone know whether the 12V battery is just an "old school" sealed lead-acid battery? Or a gel battery? Or maybe (unlikely I think) AGM?

Thank you.

The original is just a normal wet battery but low/no maintenance. When I replaced mine it came up as taking a normal one that I can top up.

Double check which car the battery is for, I think the one for the EV is a slightly different size than the ICE one.

Is the 12V part of the original warranty?

I am having trouble with my 12V since almost 30K KM and Kia says it's fine. Now since yesterday i have to jumpstart it everytime i start the car.

If the 12V is not part of the warranty i'm just gonna buy a new one and that's it. i'm at 64000KM Soul EV Base 2015.
