2015 Replaced 12v Battery

Have a 2015 Volt with the original 12v battery. I've been running load tests every month and its declining health was starting to concern me. I hate getting stranded and decided to be proactive and replace it. Getting a replacement battery turned out to be a bigger problem than I thought, no doubt the result of supply-chain issues. In the past, I've always been able to pick up a battery for other cars at Costco but none of their stores within reasonable distance had one for the Volt. Thought about getting one from a local auto parts store but their prices weren't much cheaper than one from a local Chevy dealer. Having experienced installation problems with "exact replacement" after-market parts, I decided that going with Original Equipment (OE) was a safer approach.

A local Chevy dealer had the required battery (AC Delco EVLN2 AGM) in stock. It wasn't as fresh (Feb. 2022) as I wanted but I didn't have too many choices. Installation was pretty straightforward but I did have a problem getting the mounting strap back in place before realizing that the battery has a slot that it fits into, otherwise the battery sits higher and prevents the mounting strap from being properly installed. I shudder to think what other problems might have surfaced with an "exact replacement" after-market battery.

I bought mine at AutoZone. Exact fit, no issues.

I did look at what AutoZone offered and the Duralast H5 AGM battery for the Volt was $5 more than the AC Delco. The Duralast, however, had a better warranty (36-month vs 24-month free replacement). The fact that the original AC Delco was still going after almost 8 years made my decision for me.

I got mine at Costco. Perfect fit. Same specs as the AC Delco. 3 year warranty. $179

Saw this thread and makes me think about my bat-tree... 150K miles, 7 1/2 years old and still on the original... I guess it's time to get a new one in there before cold weather and all that...

Hello I also have a 2015 Volt with the original battery. For a long time I was getting 41 miles on a charge but that has been declining over the past couple of years. This morning after being plugged in all night it only showed 31 miles' worth of charge!!! Some questions for you all:
1, Does this happen to everybody with a Chevy Volt?
2, Is the battery the problem, or could it be something else?
3, My battery is still under warranty. Is there any chance Chevy would replace it for free?
Thanks for your help!!!
