ACDelco Gold 49AGM (88864539) 36 Month Warranty AGM BCI Group 49 Battery

Order carefully, get the right battery and you'll get a perfect fit. Often times, even though the listing says, "Fits your car" it's not really an oem sized exact fit. This was, and the slight increase in cranking amps helps too.

This battery was for my Mercedes S500 and worked until this winter when one morning no crank. Tested and found it only charged to 6.3 volts. I read the warranty info provided by Amazon from the Delco company, which only gives one alternative to return to dealer. That is to buy another battery and call a number with both old and new receipt info. I did, same one from Amazon. The Delco number sent me to another number who demanded pictures etc and is sending me a new battery now, so I have two new batteries soon, but the service was very fast and helpful.

So I bought one of these, put it in the car. It lasted a few months so I got a replacement and Amazon gave me a replacement and it died in a few months so I asked for a refund because it was under warranty even the original one was under warranty except when you talk to the manufacturer like Amazon told you to they say Amazon is responsible for the warranty and refunds. They filed a claim with Amazon for a refund. They approved it, but Amazon did not. I had to buy another battery from Amazon which has been working well, but Amazon will not approve a refund on a product that the manufacturer approved a refund on because two of them were bad. Let’s see what they do, but I would not buy one of these or recommended to anyone.

Good quality battery, made in Germany. Charged. But was delayed 2 times. Arrived 1 week later. Fit perfectly in my BMW X3 F25 2011.

First off, as of August 2nd, 2024 this item is titled "High density negative paste, improves performance and increases battery life" on Amazon. This is a ACDELCO 49AGM battery. I genuinely thought this was a scam but still bought it because somehow it was cheaper than it was on RockAuto.Bought for my 2011 Audi S4, had zero issues installing it. Car started right up after install. Make sure to reprogram your battery if your car requires that too. Otherwise you'll have another dead battery in 6 months.From the reviews I expected this to arrive a week late in a broken box, but no. It arrived the next day in a completely good box with plenty of instapak around the battery. I'll be sure to update in 6 months or so after winter months to see if it can hold up to what it claims.

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.
