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.

Got this battery on a prime day deal. These are excellent quality batteries and a very good value even without the Prime Day discount. Over100 more cold cranking amps compared with the OEM Mopar battery and a 3 year warranty. They came packaged very well and fully charged. I noticed a big difference in ESS performance.

This is a great battery and an excellent value. My hybrid car came from the factory w/ a smaller 35AH lead acid battery which, surprisingly, lasted for six years. However the manufacturer has the computer in the vehicle set up to maintain a steady draw for sensors and telemetry and the vehicle quickly went into a "hibernation mode" to preserve power. The vehicle comes from the manufacturer with the correct mounting point for this larger size, 70AH AGM battery and it fits and works perfectly. No more "hibernation mode." Excellent value, this battery is from a good name, quality manufacturer and is much cheaper than most other AGM batteries the same size/specifications.

Good product works great in the tractor that we had to put it in

WARNING!!!! Don’t not buy this battery I bought it April 12 and only had it in my car for 3 weeks and it died I mean I couldn’t even jump it it was dead dead 💀 thought the cold cranking amps as advertised would work on my car well Amazon cold not of been more wrong there is no way this battery was brand new as soon as I put it in my car I noticed my battery Gadge was not even half way so on account of Amazon not honoring their return policy on car batteries they definitely got me big time. Never again will I buy a battery from amazon.

Purchased this to try to fix issues with the factory-installed battery in my 2020 Ford Escape Hybrid - kept having the vehicle enter a low battery mode while parked. Ford ships these vehicles with a lower capacity battery that tends to not work for people (search "Ford Escape Hybrid 12v battery issues" and you'll see examples). I decided to replace the old battery with this larger capacity, AGM battery over cheaper brands and am very happy I did so. It solved the low power mode issue - haven't had any problems since I swapped it out. The product arrived in robust packaging that made me feel it was transported well, and it was SO nice to have it delivered instead of having to drag it out of a store (they're pretty heavy). Install process was pretty easy, just search youtube to find others that have done this as well. The battery is under the spare tire in the back of the vehicle. This battery is just about as big as one could be and still fit under the spare in my vehicle. I did not have to make any modifications to the vehicle itself to make this work... just had to move the battery holding bracket to a wider mounting location, which was no issue. To do the job, I found it incredibly helpful to have a socket wrench set, so definitely make sure you have that before starting to remove components. When replacing the wiring, it might seem a bit tight. I had to try a couple different wire placements/paths before I settled on one that I felt was appropriate.

Huge money savings to replace dual stop/start batteries in 2020 Pacifica. Both batteries were under $300, and installed by mobile mechanic for $70. Dealership quoted $900 with 2 year warranty. Auto parts store said they did not have staff to install but would sell for batteries only for almost $500. So this was a heck of a deal. One week later, all good, everything works. This is smallest battery of the two needed for the stop/start funtion. As noted my Pacifica needed two specific batteries for stop/start. Be very careful to research the exact models that will fit your vehicle.

Save me a trip to the auto parts store. It’s been in my car for about six months and so far so well.

It fits my 2015 C class and works well so far

Not bad but not What was expected
