Description

Certainty starts with GM Genuine Parts and ACDelco. It builds on a legacy of innovation and quality that keeps pushing us forward. Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store More and more vehicles have complex electrical systems and fuel savings modes such as Start/Stop that rely on battery power to help enable performance. Some vehicles integrate secondary or auxiliary batteries as a part of this complex electrical system serving multiple functions. ACDelco AGM (Absorbent Glass Mat) and AGM Auxiliary batteries are designed for vehicles with these increased electrical demands. ACDelco Gold parts are high-quality OE alternatives for GM vehicles and more. ACDelco Silver parts offer a high-quality value option for most makes and models. Scroll or click to learn more. ACDelco Gold Series Batteries meet all industry requirements and most OE specifications. ACDelco Gold & Silver Series Batteries are offered for GM vehicles and most other makes and models. ACDelco AGM Auxiliary Batteries support vehicles with greater electrical demands such as Stop/Start. ACDelco Silver Series Batteries are a high-quality value option offering durable performance. Along with autos, ACDelco AGM Batteries are available for marine, off-road and heavy-duty needs. How is an AGM battery different than a conventional battery? An AGM battery uses a fiberglass mat to absorb the electrolyte that’s essential for energy storage and delivery. A conventional “flooded” battery contains a liquid electrolyte. The AGM design makes the battery spill-proof and maintenance-free. What are the benefits of an AGM battery? An AGM battery’s maintenance-free design makes it spill-proof and resistant to vibrations. It also offers up to twice the life of conventional flooded batteries, along with more power and Cold Cranking Amps than conventional flooded batteries. Do I have to replace an AGM battery with another? Yes. If the original-equipment battery was an AGM battery, it’s important to replace it with another. That also goes for “aux” batteries in vehicles with Start/Stop technology and other features with unique electrical demands. What is an “aux” battery? Some vehicles use an auxiliary battery as a part of a more complex electrical system with increased demands. Typically, these “aux” batteries are used in vehicles with Start/Stop technology as well as hybrid vehicles and battery-electric vehicles. Can I use an AGM battery in a vehicle that did not originally come with one? In most cases, the answer is yes. Most modern vehicles can accommodate an AGM battery as a direct replacement. Some vehicles, however, may have compatibility issues when it comes to the charging and voltage needs for an AGM battery.

  • Shipping is kinda long
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. ... show more

  • Dead battery
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. ... show more

  • 30% the price of the battery that the Mercedes Benz dealership was trying to sell me.
30% the price of the battery that the Mercedes Benz dealership was trying to sell me. It’s been several months and I have had no issues and the 3 year warranty is the cherry on top.

  • Perfect Battery for 2013 Mercedes-Benz E350
This is the second time I purchased this battery, the first time was 4 years ago when I was in need for a new battery for the E350. This ACDelco is a perfect fit and the car starts just like you would expect from the actual Mercedes-Benz battery (for a fraction of the cost). As I do not drive this vehicle often, the battery often gets neglected, but it was completely reliable right up to the last day. This battery was very professionally packed and arrived faster than I expected. No damage, direct fit, and started the car and the rest is history. I have used it for a few weeks now (with a week of the car in storage and not being started at all), and when I went out to start it again, it started without any issues. If you are looking for a good battery replacement for your 2013 Mercedes-Benz E350, this one would be it. ... show more

  • So far, so good.
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. ... show more

  • Volkswagen Complexity, Good Battery, Bad Shipping
I feel as though this battery and I got off on the wrong foot from the beginning. I had seen another review mention long shipping times, and they were 100% correct. This battery took 2 weeks to ship out to me, missing its first expected delivery date by almost a week. I was explained that this was not normal shipping with this item, but I have a feeling it is. When the battery finally got to me, it was exactly as the listing said, however, I would've preferred that the battery came with a replacement battery vent tube. I installed this battery in my 2008 Volkswagen Touareg. As with everything else in this vehicle, the installation was made difficult as the battery compartment for the SUV is under the driver's side seat. I had watched multiple videos on removal/installation and felt comfortable with changing the battery myself, as I typically DIY most of my vehicle repairs. Ultimately, the battery was installed, but if you have back/shoulder issues, I would not recommend you install this battery yourself in this particular vehicle. As previously mentioned, this battery has worked great since installed yesterday. My vehicle sat for 6 months and started right up. I feel confident with the 36 month warranty that if I have any issues, it will be resolved. As mentioned, the lack of an included vent tube did make my life a little more difficult, but that has since been resolved. Overall, a reliable battery, it just took forever to get to me. I do not believe the $50 savings between ordering a battery on Amazon and getting it in store is worth it considering how long you have to wait to get the battery, especially with the shipping times expected with most items nowadays. ... show more

Fit perfectly in my 2017 BMW 230i. Easy install. OBD worked great to link this battery to the car.
