my 2012 gs battery looks like you can pop off the caps to check the level.question is are you supposed to pop off the caps or does it look like the caps come off but it is really sealed.

cyber gray

yes they are sealed

The factory battery on our 2009 was not sealed. There were two caps, each cap covered 3 cells.

After a year or two I very carefully pried off the caps, verified that the electrolyte level was normal, and then put them back in place. No problem.

The replacement Delco we have now looks similar, but I haven't messed with it.

My '09 has the caps. First time i took them off noticed the acid was low in several cells. Used distilled water to bring it up to the correct level. I check the level about twice a year.

Can you? Yes. More than likely so you can check the specific gravity of the solution with a hydrometer. Should you add fluid? No. It's billed as a maintenance free battery and thats exactly what it is.

I've always used distilled water, never had a problem

I would add water if the cells are exposed. Maintenance free or not!

Distilled, or "de-ionized" water should be used.

Rebel 1

Yep, as i stated "Used distilled water to bring it up to the correct level."

If you are under warranty, why do you hate new free batteries from GM?

This is at least battery related. I had to laugh when I found a sealed AAA battery looking kinda out out of place in the one owner 06 I found at Jimmy Vasser Chevrolet in July. In reading over the complete service history I noticed they had recommended that the PO have it replaced some time back. Apparently he didn't and had to call AAA to get started one day. Except for that one item, every service/warranty interval was accounted for and performed by the dealer he bought it from and traded it back into. Nice having that kind of verification of the car's history.

I used distilled water years back, over time stated using regular tap water. Discovered it really didn't make any difference, tap water batteries last 5 to 6 years.

The tap water issue really becomes an issue when it has things in it like...minerals. The minerals will create a "short" in the battery killing it very quickly. Do not risk it and put in distilled water or deionized water. It's cheap and will work.

My 13 is not sealed.

Yes add water!! I had to add distilled water to 2 cells in my 13. It was low from the get go.

I am surprised that they still make batteries where you have to add water...I am glad that my battery is truly maintenance free!

I did the same with my 2005 battery as it was low. Now it is on a battery tender.
