Battery replacement recommendation?
 

2010 Hummer H3 Alpha. 46K. Serviced regularly.

Anyway, yesterday, while on vacation, the car was parked and I was sitting in it for maybe 10 minutes with just the radio on, the windows open catching the sea breeze and then went to turn it on. CLICK CLICK CLICKTY CLICK. H3 won't start.

Tried again. Same thing.

Called OnStar and another service. OnStar sucks. Period. They take forever and half the time don't have what is required. Anyway, H3 starts up with a charge. Destination is 20 minutes away. H3 stays on. Get to restaurant. Go out a few times to make sure she starts. She does. Gas up for the 120 mile ride home. She starts again. This am, she starts again.

Regardless, I want to change the battery, so after a long story, any recommendations on a reliable battery?

By the way, there are no mods or pre-amps or any nonsense in the H3, stock GM navi with XM, DVD players in the head rests (never used) and nothing else.

Appreciate a few rock solid recos.

Thanks.

If you still have the OEM for absolute crap battery terminal connectors, I would change those while you are swapping the battery, or even before that, with a quality aftermarket set, like Stingers (or your favorite brand). Fist mod every H3/H3T should have.

Any group 86 AGM battery will do. The terminal connectors are way more important.

First time I am hearing about this (I've had a Hummer since 2006).

Anywhere I can read up on this and see what to do?

So hitting Costco for a group 86 AGM battery will be OK?

Buy American, your rig deserves it!

I just bought 1 last week to swap out my 2yr old optima, paid $76.04 for the 86 gold diehard and sold the optima on cl for $75.00..

Who produces a true 86 AGM? :confused:

all my diehard batts died hard in about 33 months so i quit them 3o yrs ago.
btw it dont take much,any good batt will do.

just for info i put my lawn tractor tiny batt in my h3 and used it for a day!!

dont know about -10 in feb though!!

Diehards were produced by johnson controls made in mexico, Diehards are now made by deka in pennsylvania..

Where did you get it for that price? All I get is $135.00 for that battery.

States it is for Northern weather. Need one for SoCal weather. Temps as high as 110º.

Any suggestions?

Any thoughts on Bosch?

A 4 year old battery should still be good.
I pulled my OEM battery out of my 2007 H3 when I installed dual Optima's. I put that OEM into my 1965 Dodge Firetruck and it's still going strong.

Like Doc mentioned, change those crappy OEM battery terminal connectors NOW.
I would do that before buying a new battery and see if that takes care of it. Bad connections can cause a whole lot of electrical problems including charging the battery but especially messing up the BCM.

Changing those terminals is the FIRST thing every H3 owner should do whether you have issues or not. It's just a matter of time, you will.

OK, got it. Can you, or anyone, tell me what I am changing them to?

Look for either Stingers, or the military type. Do not use the universal cheapo's
Just remember that POS & NEG posts are slightly different diameters. You need to get one of each connector. They are marked + or -.

You can get Stingers from Amazon or other online places

Autozone has some good ones as well.

These are the military type, also available online.

I'm at the 3-year mark with a Bosch premium battery in my Pontiac and so far so good. It was a good deal at Pep Boys at the time so I thought I would give them a try.

Otherwise I use AC Delco but they are now hard to find in my area at a decent price. When used in a daily driven vehicle, they last as long as the rating printed right on top of the battery. The 6-year ones for example, have always lasted exactly 6 years for me.

I put an OPTIMA in my F-150 a couple years ago..Absolutely no problems. Needed to replace the '06 battery last month. Replaced the cable ends years ago. Looked around for the best OPTIMA price..Amazon beat oReilly by $70 .including shipping. Took about 5 days to get it...

Many brands, but I am pretty sure they are all actually made by DEKA, Johnson Controls, Exide, Duracell.... blah blah blah. Yes some of them say for example "group size 75/86" or the like, but they fit properly in the H3 battery box.

I don't bother with Diehard for years, never been impressive. The last couple Optima batteries I had were leakers, and I thought they pride themselves on being nearly leak proof????

IMHO, the expensive brands just suck cabbage out of your wallet faster than the Sam's Club version of the same things.

I've seen the dual terminals, however I'm looking for an 86 agm with only 2 holes into the case. AGM technology is the way to go, however I haven't found an 86 agm with only the top mounts.

good to no made in the usa, ill check in to that when i need a battery. We all should try to buy more made in usa when we can

So when searching for battery - search for Group 86 for 2009 H3?

i go to walmart and get the biggest that will fit the car. all the same price.

k.i.s.s,

Optima AMG yellow Top way to go! plenty reserve power starts every time I ordered mine on amazon shipped fast. Best battery I used on my 2009 H3

i second bugger , i changed my ****ty oem battery with an optima haven't done terminals yet, best battery in my opinon

mines the red top with a bit of mod i fitted it into my 09 h3, starts every time regardless how long i leave the car garaged

Which if any Red Top model fits with no mods?

Diehard Platinum in mine.
