At 55k miles, I took a peak of my battery (still original one) and the eye went clear. It was no longer green and the eye's color became clear with a yellow band being visible. A google search suggests the battery is going to soon die, so I decided to replace it.

Walmart's Evergreen Maxx is top rated by Consumer Reports, so that's what I chose. It's model 24F for the 4G TL FYI, and comes with 3 year free guarantee replacement, and has 750 cold cranking amps, and should last until >100k miles or when I decide to trade in the car.

Taking out the battery was a pain in the butt. I was in the Walmart parking lot looking like a gangsta.

After disconnecting the negative end (black) first, then disconnecting the positive end (red).... there is a strap that crosses the top of the battery held by two long rods I had to unscrew; then there is what appears to be a lid that goes on top of the battery. The battery is heavy as heck, and having to hike it into the store to get it a core credit. And then bringing the new battery back.

Installing it was a chore. The new battery is actually a little taller than the OEM one. After reversing the tasks I listed above, the dam engine cover wouldn't fit properly. So after fiddling around, I discovered the lid that encapsulates the battery doesn't fit the new battery, causing the "strap" not to screw in properly.

In the end, I decided take off the lid and left the battery uncovered, and then was able to screw in the strap to secure the battery. Now I have a battery lid lying around the garage lol.

Ordeal took over an hour of fiddling around with people staring at me in the parking lot. Just sharing my lovely experience on a Friday morning...

 

I replaced mine with the same Wally brand in December. Had to do the job TWICE! Within the same week, my TL and wife's MDX's battery went in nice cold winter. I didn't bother changing in the parking lot in fear of losing my fingers due to frostbite. It took about fifteen minutes to change, but I did notice that the battery cover didn't fit snugly anymore. I cut the lifting strap off Walmart battery to see if that made any difference, but it didn't.

 

Thanks for the heads up on the battery from Wally World. Just curious what others have found for non OEM batteries that fit.

 

Also FYI Acura battery warranty is 4 years/50,000 miles and i got my replaced. I didn't know batteries carried a warranty until i read it on this forum.

 

The Wally World batteries are very good, but for some reason, I've also found the dimensions aren't always right (not on my TL yet - had the usual, two-year OEM battery failure replaced under warranty. So far, so good after about 3 years). Maybe Chinese measuring devices use a different metric?

 

I have stayed away from the Walmart top rated evergreen maxx because about 5 years ago I put 2 of them into my 96 Camry Wagon and my 92 Camry V6 Sdn and they leaked corrosive battery acid from the cases & not thru the vent caps and starting eating up various wires and a/c pipes. I would watch them carefully for case leaks. This had happened in the Summer. I ended up getting rid of 2 new batteries and replacing them with Dura last batteries and that ended the problems.

 

My car battery started acting up this winter. I took the car to the dealer in January and they replaced it under the bumper-to-bumper warranty, free of charge to me. My car is 3.5 years old and has about 36500 miles on it.

 

Recent service car was flagged for not passing battery tests, but had forgotten Acura covers this as part of their standard warranty. Declined battery replacement as I hadn't experienced any issues to date, but will keep an eye on this and maybe even ask for replacement under warranty.
