ACDelco Gold 49AGMHR 36 Month Warranty High Reserve AGM BCI Group 49 Battery

Good battery. OMG , they are heavy tho. Changing out a GL350 under the seat is a chore.

Purchased this battery for my 2016 BMW M-Spec 328i. Exact fit to replace the original BMW-labled battery that came with the car. I kept the memory in my car before i disconnect the old battery, put this ACDelco in, programed it to my car so that the car can communicate with it properly and all is fine.My engine stop and go system works fine and everything else works great, put my battery analyzer on and it is reading great, when engine is off and when engine is on, also when load is applied, such as headlights, hazard lights, AC, radio etc.great product. If I get a life span of three and a half years or even three years, that would be great, would definitely purchase again.

After 3 months the battery wasn’t working anymore. Maybe it was a lemon but it looks like I’m not the only one here

I recently purchased the ACDelco Gold 49AGMHR battery for my Porsche Macan, and I couldn’t be more satisfied. The installation was straightforward, and the battery fit perfectly. It provides excellent starting power, and I noticed an immediate improvement in the car’s overall performance. The 36-month warranty adds peace of mind, knowing that I’m covered for an extended period. ACDelco’s reputation for quality is well-deserved, and this battery lives up to that standard. Highly recommended for anyone needing a reliable and powerful battery for their vehicle.

Diagnosed my battery to be failing and the need to replace was dire. Did some searching and although it's an expensive battery (I know lithium batteries are ridiculous), this was the most reasonable price I found. Sorta straight forward installation in a 2007 Mercedes S550, albeit a bit of work crawling into the trunk to R&R.Note: If things like comfort setting aren't working properly or your radio and climate control start shutting down sooner than expected, these are all signs of a failing battery.Note 2: Specifically on the 2007 S550, there are two batteries in the car. Check with someone/place that knows for sure for your vehicle.

Needed a new battery since the original one was still in the vehicle from 2018.Installed as it should and once the Ford battery reset procedure to reset the battery monitoring system was done it was ready to go.

A/C Delhi battery always work perfectly

I should have verified the size of the old battery before ordering this one. I searched the internet and this battery had the same dimensions as other batteries that came up as a direct replacement. The battery was too long and a little too tall. I had to build a new battery hold-down bracket to install it. The cover panel latches back in place but not quite like it should (not fully down on the right side) because of the height difference. I hate to give a low rating on the battery because I won't be able to determine that until after at least a few years of use. But I gave it two stars in hopes that another W2K Jeep owner is considering purchasing this battery and reads the lower star reviews and catches it before they order.
