Perfect fit for a 2001 Mercedes CLK55. Cranks the motor noticeably quicker than the old one. I’m gone for a few weeks at a time and I read that AGM batteries lose less charge when sitting unused.It came well protected a heavy foam padding on the bottom of the box. The shipping box was heavy cardboard.Jan 2019- Battery is still going strong. No issues with the battery so far. I notice that Amazon now states that this battery won’t fit my car. I wonder what’s going on. I notice a Delphi battery of the same group size is okay for my car.The physical size of the AC battery fits perfectly into the battery holding bay.Feb 3, 2019. Battery is holding up well. With a battery tester it shows the SOH (State of Health) at 90%. Not bad. During the first couple of years I was always gone for most of the month. The battery basically received a charge once a month.May 11,2011: The battery has been holding up well. I check it will a battery tester maybe every couple of months and after using a trickle charger and then running the car for a day the SOH can go over 95%. I use a trickle charger on it for a couple of days every few months. This is easily the longest battery I’ve ever had. The one thing different I do now is I use a Ctek battery charger to give it a day or two of trickle charging.Oct -2021- It’s not reaching maximum voltage now when I trickle charge it like it used to. The state of health (SOH) measurement with a battery tester isn’t going about 82%. The battery could be reaching the end of its life. I’m going to try a longer extended time with the trickle charger to see if it can get back to the max voltage and SOH numbers.

Being used in 2008 Mercedes Benz ML 320 CDI to replace 8-year old OEM 100 ah battery, made in Spain (the AC Delco is 95ah and apparently made in Detroit, but not sure from labels on it.) The AC D is a 900 CCA battery. Good price & free shipping; had to pay sales tax.The AC D arrived in excellent condition, on time, and was very well packed; heavy duty box with padding on all 4 sides, and top and bottom. Put it on a 2 ah charge, and it registered full in about 45 minutes. From the looks of it, it is a very recently made battery. Perfect fit. Came with a plug for one end of the AGM ventilation system.Replaced auxiliary battery at the same time. Bought it online at Batteries Plus for Twenty. Unless you know about it, that little battery is a pain the arse to replace. It has a simple pressure catch on the front seat passenger side of the long edge. If you aren’t aware of it, you will have a *&^(%^% time removing it.Mercedes Benz seems to take great pains to complicate and obfuscate simple things, probably to assure dealerships a profitable repair business. I won’t go into detail, except to say the location of this near 60 pound battery is absurd; red Loctite was put on both terminal bolts; and the positive terminal requires a triple jointed wrist to remove. Will never buy another M-B. Just tooooooo much unnecessary complexity. Germans need to practice KISS – Keep It Simple St,,,,,Car started up with vigor; was laboring before replacement. No problems with radio and other electronics.Five stars in the interim; will come back if there are problems, which I don’t anticipate.

I recently purchased the AC Delco Gold 49AGM 36 Month Warranty AGM BCI Group 49 Battery as a replacement for the battery in my BMW X5 2011, and overall I am satisfied with my purchase.The battery itself is of high quality and provides reliable performance for my vehicle. It has a 36-month warranty, which gives me peace of mind knowing that it is a durable and long-lasting option.One downside of my purchase was the shipping time. It took longer than expected for the battery to arrive, which was inconvenient. However, I was able to get it at a cheaper price than what I would have paid in-store, which was a positive.Installation of the battery was straightforward and easy, and it fit perfectly in my vehicle. Since installation, I have noticed a significant improvement in the performance of my car, which is a great result.Overall, despite the shipping delay, I am satisfied with my purchase of the AC Delco Gold 49AGM 36 Month Warranty AGM BCI Group 49 Battery. It is a high-quality and reliable option that has improved the performance of my car, and the 36-month warranty provides peace of mind. If you’re looking for a replacement battery for your BMW X5 2011, I would recommend considering this option.

Thought I was saving money, but it ended up costing me more in the long run. After I installed it, my truck wouldn’t turn over. Ended up getting it towed thinking my starter was bad. Mechanic said the battery was dead and couldn’t be charged. Ended up spending over $100 more on a battery from my local auto parts store, paid another $85 to have installed by my mechanic shop since my truck was towed there. Lost a whole day of work and the hassle of trying to deal with this plus the additional $185 I paid for another battery and labor. This turned out to be a very frustrating situation. Not sure if there’s quality control on inventory of these car batteries or if they even test them before they sell them to be sure they have a full charge.

Was extremely pleased to see the unit was “made in Germany” and that it had the exact features, size and install pieces as the unit for sale through the MBZ dealership at a much more reasonable cost.
