Battery group size

[PsychoAzzBabe]

Hi of course I need to replace my battery. Looking on BatteriesPlus + website. I know AGM battery. What is group size, and what size do I need?

I believe you want H7/L4. The below link has a few different battery options listed by their European spec, but the first one is the AGM that we get in North America. To double check you have a reasonable replacement, make sure it reasonably matches the 80-90 amp hours, 800 cold cranking amps, and ~150min reserve capacity.

my 3.3gt2 uses an H8 or group 49. H7 is probably for the 2.0.

FWIW, some mfr's H7 has as much CCA and reserve capacity as, if not more than, other mfr's H8.

Take Optima, for example. They don't even make an H8, as their H7 is already pretty stout. I might get that if ours needs replacement. The Optimas I've had were quite impressive in their performance and longevity.

That would be my choice

That's interesting...on several Kia parts websites they showed the same OEM part number for the 4cyl and 6cyl models. When I image searched I found some AGM90L in addition to the AGM80L, but didn't see it specify H8, so it's not clear whether it's that size or just a higher capacity H7.

However, the two form factors are the same height & width, with the H8 just being a half in longer, so I guess pick your capacity and either size will fit. On one of my older cars, I was in a cold climate and my battery tray was just long enough to fit a size up from OEM so I did that for the extra cold cranking amps (I could've just gone to an AGM with more power at the same size, but they were more of a premium then).

I just replaced mine 2023 GT2 3.3t it's an H8 for my car, got it at auto zone because I needed it immediately, $266. You'll need 10mm and 12mm sockets
