Works great on my Pacifica.

Swapped out the original 2013 auxiliary battery on my Mercedes Benz SL 550 with the ACDelco Gold AUX14-200, and it’s been flawless so far. This AGM unit delivers **12V, 12AH, and 200 CCA**, perfectly matching the factory specs. It arrived fully charged and sealed — no venting required, just drop it in and go. Install was mostly straightforward. One caveat: I had to slightly modify the top battery cover using a Dremel tool to accommodate the terminal layout, which differed slightly from the factory battery. It wasn’t severe, and the mod was quick — but worth noting for SL 550 owners. Vehicles with different cover designs may not run into this. Performance has been spot-on. No issues with ECO or Start/Stop functions, and it’s handled the summer heat without breaking a sweat. The original battery lasted over a decade, so I’ll be watching how this one stacks up — but with ACDelco’s 36-month warranty, I’m confident in the investment. *Solid AGM battery at a fair price, with OEM-level performance and peace of mind.*

Battery lasted less than 1 year. Won't hold a charge. 3 year warranty, right. Have to go thru Amazon for warranty, according to AC Delco website. there isn't a support link on Amazon.

Fits my 2014 Mercedes CLS 550 auxiliary battery replacement perfectly with no modification. 10 minutes install in the trunk near the spare tire. Auxiliary battery malfunction error code cleared as soon as I installed the Delco.

Knowing the reliability of the Delco battery brand and the cost at Amazon were determining factors for this purchase. Several of the 'large auto parts retailers' had the same item at a much higher price. It was a 'no brainer' to purchase from Amazon. Not concerned about a possible warranty issue, since it is a name brand item and most aftermarket suppliers of this brand will warranty the item if necessary. However, after having use Delco batteries for many years, it is highly doubtful that is should ever be an issue. The battery for purchased as a replacement for a late model Dodge Durango. The fitment was correct; however, installation was a bit of a chore. Not the fault of the batter type but with the OE design of the battery placement. The placement of this battery and the 'primary battery' is under the passenger seat. This unit is a 'auxiliary' battery for the 'Stop/Start' system for the vehicle. Highly recommend this unit if it satisfies your requirements. Delco is a brand for one of the major battery manufacturers and has a very good reputation in the aftermarket business.

Great battery worked well for the benz gla 250 as the alternative battery

This battery was a direct replacement for the stock battery. It comes without posts but the posts on the old battery were easy to remove and re-use. Several months later, and all functions are working normally. I followed the replacement instructions shown on YouTube, and everything went flawlessly.
