Not an exact fit for 2015 MB SL550
This battery is not an exact fit for a 2015 MB SL550. The posts are in the wrong spot and the safety cover will not fit (and if it did the post holes will be inaccessible). Thus, you will need the OEM battery that puts the post holes in the center of the battery, not on the side.
This was a waste of a Sunday afternoon.
Bottom Line No, I would not recommend to a friend
Good Aux Battery Replacement for Jeep JL Wrangler 3.6
I've had this in my 2018 Jeep JL Wrangler since March and it has had no issues. I don't use the ESS except on very rare occasions, so it doesn't get much stress, but it handles it just fine when I have tried it. At least on paper, it should be better than the OEM aux battery, given that it is an AGM battery. I intend to replace it at 5 years, even if it is still working. It also fit perfectly.
I will buy it again if it last
It is the AUX battery in a 2019 Chrysler Pacifica, the ESS system malfunctioning, read on the internet that is usually caused by a weak battery. The techs at Advance Auto ran a load test and found the battery weak. I replaced it and now my ESS is back to normal.
