Battery Options?

[G8 GT V8]

I think my G8's battery is on its last leg. What are some of the better options for us?

I just changed mine. Thats what I get for it being a garage queen. Only lasted 4 years,

I ended up purchasing a battery from Carquest. Its their premium platinum battery. It is 800 CCA and has a 7 year warranty. I only paid 145.00.

Its made in the USA and is made by EastPenn.

I second Curts opinion, it seems to have worked for mine too!

Lol - let it be known that I have driven it way more this year. Just no quarter mile runs yet, but that will change when the cooler weather sets in :)

Thanks!!! I'll have to check them out. Price sounds pretty good too.

I made a list of the 94R/H7 AGM batteries the other day after researching other batteries for the minivan. Since I don't plan to use a wet cell battery in the G8, I didn't bother looking at them. Unfortunately, the Consumer Reports battery comparison from a few years ago didn't include 94R or H7 groups, but it's a decent read for other battery groups for other vehicles.

DieHard 50793
Duralast H7-AGM
Advance Auto Parts/Autocraft H7-AGM
There is a fair chance that all the above are actually the same battery made by Johnson Controls.

Exide Edge FP-AGML4/94R. This is the only one on this list with a 4 year warranty; others have 3 yr. It's the most expensive too.

I don't think you can go wrong with any of the AGM batteries.

[kevinm0131]

Just checked consumer reports for the latest and greatest, again no 94R or H7 ratings, but in the other groups:
Diehard Advancec Gold in 2 categories
Diehard Gold one category
Everstart Maxx 2 categories
Interstate Mega-Tron II in one

I installed the optima yellow in my G8 last year and am very happy with it so far. Used optima's in all of my vehicles in the last 15+ years without issue. Some say quality has changed but I haven't seen it.
Install did require altering the hold down bracket but nothing that I didn't accomplish in 15-20 minutes.

The East Penn batteries would be my first choice. I didn't have access to one though and went with my second choice the Exide Edge. Don't buy one over a couple of months old that's been sitting on the shelf. Local major chain had two on the shelf that were over a year old.

Very good point.

When I purchased my Platinum from car quest they ordered one and got it the next day.
They did not stock big batteries like that at their location.

I just installed the Walmart H7 Everstart which is manufactured by Johnson Controls. It was $139.00. Charged it fully before connecting it. Initially I was concerned because engineering mode indicated % of charge of .7% for the entire day. Also, voltage fluctuated to 15+ but the next morning all was back to normal. Charge 75% and volts @ 14.5 while running. Everstarts have a 3 year full replacement followed 2 years pro-rated replacement.

[WhatNext]

Did a Walmart ever start too. I see they went up in price (was $120). All the auto stores were selling at $160.

First day my voltage stayed up also even though I drove it for hours. But others said the same happened to them and no long term effects apparently. Must be the on board brain getting comfortable with the new battery.

[G8 GT V8]

Thanks guys...I hadn't even thought about Wally world having one.

Great point on not getting one that's been sitting around for a while. I'll keep that in mind.

[WhatNext]

Yeah, had to go to another Walmart to find a fresh one too.

[G8 GT V8]

I ended up going with the Duralast H7-AGM, but damn it was hard to find one. You can't trust the online inventory status. Felt like I was on a wild goose chase for 22 LR ammo...

It seems to be doing good so far.

Thanks to all that chimed in.

Have to replace the battery after almost 6 years. I see the recommendations here on batteris. Any part numbers for batteries that don't require battery tray/hold down modifications?
Thanks in advance

See my post above yours. My new battery did not require any battery tray mods. It was a direct bolt in like the factory.

I will and thank you.

I just had the Interstate 94R/H7 installed. Since my vehicle is a 2008, that battery was five years old already. Recently I had two electrical incidents springs up, one, the car was completely disabled one day (not even the interior lights would come on when opening the door) and I had to be jump started, and two, I had a Check Engine light this past week. I am hoping that both were the result of a battery that was going bad.

[Tuclis]

If you had an AGM battery im surprised it went bad already. AGMs have been in the aviation/military for a while partly because of their durability.
