ACDelco Gold 48AGM (88864541) 36 Month Warranty AGM BCI Group 48 Battery

I have had this battery for 18 months now, and I'm very happy with it thus far. I've been using AGM batteries in my work for quite a few years (stand alone solar powered automation and control systems) and they are very good performers when treated properly. I've seen them last as long as 7 years in 24/7 duty which to me is quite impressive considering that they're maintenance free. I live in the high desert of NM, about 3200 feet above sea level, and the dry climate and extreme temperatures, regularly above 110 degrees in the dead of summer, wreak havoc on traditional flooded lead acid batteries. They require constant acid level checking and even still always seem to die an early death. In the application I've implemented this battery in, my 2011 Suburban Z71, I'm constantly off road and my truck sits idling regularly on job sites, with underhood temps at very high levels. My "wet" batteries prior to this one generally last a year to 18 months, and the last 3-6 months of their lives are generally indicated by slower cranking and extremely fast discharge with small current loads like my cell phone charger being left on overnight, which honestly is the norm for me. I also run a large inverter for power tools on a regular basis; it's hard wired in and mounted on the floorboard of the vehicle. At 18 months in service this battery still performs like new, which it makes it the best battery I've had in my primary work vehicle in many years. For reference, I've been using the top grade (most expensive) WalMart batteries and my results have been somewhat disappointing, as previously stated. I live in a small town and don't have a lot of choices with things like automotive batteries. The 3 year free replacement warranty gives me a warm fuzzy but I'm betting (and hoping) I won't need to use it. I'm preparing for my second winter with this battery but I'm confident it will hold up based on its performance thus far. Chances are I will own this vehicle until this battery finally fails, and at that point I will update this review. For the time being, it's everything I could ask for in a battery, with lots of cranking power and reserve capacity, and it has done very well with the somewhat extreme workload I've placed upon it. Some big strides have been made in AGM technology in recent years, namely higher current output which makes it more appropriate in automotive applications, and this battery bears that out nicely. I'd say that it's everything I had hoped it would be when I made the switch to AGM for my primary/work vehicle, worth the extra cost in extended life and less hassles with maintenance. I switched to AGM with my Honda GL1800 motorcycle a couple of years ago and the results there have been stellar as well. I hope that my review helps with your purchase decision.Update 10/2/17: Still going strong at 2-1/2 years in service and zero maintenance. Chances are that ACDelco Pro AGM will be my new battery of choice, in spite of the higher price than conventional batteries. Well worth it to me; it appears that longevity will more than offset the price differential. And the less I have to extract a dead battery from my engine compartment, the happier I am.Update 9/7/2018: Still performing as new, 41 months in. It's a keeper.Update 2/27/19: Made it through another winter with no issues. I'm so happy with this battery at almost 4 years in service.Update 11/8/19: This battery is still happy and healthy at 4.5 years in service. Starts my 5.3L V8 Suburban reliably in recent subfreezing weather. I should also mention that my battery terminals are clean, shiny, and corrosion free; it looks like the battery terminal posts are very well sealed against acid and fumes leaking out and destroying cable ends and clamps.Update 4/22/20: 5 years in service without so much as a hiccup. Still plenty of cranking power and zero issues. The extreme workload I mentioned earlier in this review has diminished somewhat these days. My Suburban is more of a daily driver now, although I still use the large inverter regularly for this and that. I replaced the factory alternator at about 105K miles in this vehicle; it was still charging just fine but the bearings were starting to get dry and a little noisy, and I didn't want it failing on me at an inopportune moment (like being many miles from home). But I digress...I'm super pleased with this AGM battery purchase 5 years later. It's been awesome, and shows no sign of giving up anytime soon.Update 10/19/20: 5.5 years in service and still going strong.Update 12/15/20: With subfreezing temps in the teens over the next couple of days here, I thought it best to do a quick health check of this battery considering it's age. I used a carbon pile load tester and it's putting out about 395 Amps at 50 degrees F, which is probably double what I need for cranking. I'll be keeping an eye on its freezing weather performance but I think it will do well.Update 3/1/21: This ACDelco AGM battery made it through the recent Arctic blast with no issues; reliably started my Suburban at 5 degrees F. It's 2 months shy of 6 years old and still going strong.Update 5/24/21: Just passed 6 years since installation, and still working great. Possibly the longest lasting automotive battery I've ever owned.Update 11/5/21: 78 months / 6.5 years in service and still going strong. Temps in the 30s here this morning, and it's still cranking with power to spare.Update 12/12/21: Subfreezing weather has arrived, and this battery is finally showing its age. Slower than normal cranking this morning at 26 degrees F. I conducted a load test and it's down to 340 amps max output. I've seen a lot of sudden failures from traditional flooded batteries over the years, and the failure curve on this one seems to be much more gradual. It's nice to have some warning of impending failure, instead of having to arrange a jump start. I'll run it for a while longer as it's still doing the job, but a battery purchase is in my near future. This has been a really great purchase and has lasted for more than double the 3 year warranty. I highly recommend it, and have zero complaints.Final update 12/16/21: I ordered a replacement today. It's the same brand ACDelco Gold AGM, but I ordered the Group 94R/H7 instead of this Group 48/H6. It has much better cranking amp rating, reserve capacity, and AH rating, and it's $18 less at the time of writing this at $164. It's a little longer by about .6", but otherwise is almost identical and will drop right into my 2011 Suburban with room to spare using the factory battery holddown clamp. These 94Rs are factory equipment on the '14 and newer Chevrolet full size trucks and SUVs, and have the higher capacity to keep up with the ever increasing electrical loads as option sets continue to increase (I.E. higher power infotainment systems, auto pilot systems, heated seats and steering wheels, etc.). I hope it lasts as long as this one did, and I'm convinced that it's the absolute best deal on the market if you want a long lasting premium battery.

The ACDelco Gold 48AGM battery worked perfectly in my C7 Corvette. The size was an exact match, making installation easy with no adjustments needed. It delivers strong, consistent power, and the AGM design ensures reliable performance, even in demanding conditions. A great choice for anyone looking for a dependable replacement battery.

I installed this battery in my 2017 Corvette Grand Sport and it works great. I especially like the fact that it has a handle to lower it into the very tight space for the Corvette battery. Excellent price and a great battery.

Bought as a replacement for a 2020 Ford Escape Hybrid. If you didn't know, this model year has notorious issues with the stock battery - it's tiny and under powered (I think 45 AH rating, vs this 70 AH), dies a ton and because almost everything that isn't the engine relies on it (transmission and parking brake especially!) it's a crucial component. You can't get out of park, can't even get the car to start if this battery is too low. Even simple things like the powered liftgate, and remote unlocks stop working when the stock battery goes.The Ford dealership was going to install the same stock battery (dumb), and the techs wasn't even aware that in the 2021 model they upgraded the stock battery anyway. Had to pull teeth to get someone to even pull up the model of the new battery, which finally was quoted at over $300 to purchase and install (with a 1 week lead time). Are you kidding me?Just buy this battery, same 3 year warranty, same AGM ratings as the upgraded stock and without the MotorCraft upcharge. Install literally took me <20 min, even with my socket set being missing for most of that.We'll see if it holds up - but so far (3 months in) it's been rock solid and literally every problem I've been having with this car has been fixed b/c this battery can actually keep the electronics in power.

Excellent battery at a reasonable price ($233 in Jan 2024). Got this for a 2021 Escape Hybrid. The OEM battery looks like something for a lawnmower. We were having all manner of electrical gremlins, auto door unlocks not working, screen doing weird stuff, gps showing in odd places, a few others I forget just now. A search turned up repeated mentions of replacing the undersized OEM with a group 48 so I got one of these. It was a simple replace and now all is well, so far (Feb 2025).

So far, so good! Has the power to start my truck. My outside temp gauge was off, installing this battery fix the issue, the old battery must have been on its last legs. The battery fit in the space well. Only time will tell if it can take the Texas heat an longevity, hoping to get at least 3 years from her.

Seems to be a good battery. You can't get the core refund from your old one buying online. But the savings are more than worth it. It arrived quickly and was packaged well. Feel bad for the delivery driver as it is heavy!

This battery looks to be high quality. Before removing it from the shipping box, I measured it's capacity and was surprised to see it tested at 853CCA, well above the 760CCA rating. It's been in my truck for a month so far and no issues.
