Perfect replacement for the auxiliary battery in my 2015 Mercedes CLA250!! And at a fraction of the cost of the dealer version —works great too!!

DO NOT BUY!!! I bought this Feb of 2024 for my 2018 Chrysler Pacifica. It no longer works. Amazon only has the 30 day warranty so you have to find an AC Delco dealer for the warranty. The warranty process is a nightmare!

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.

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.*

I have a 2015 Range Rover Evoque and Amazon says it's a confirmed fit (which it does), but the original battery has nub type posts like full size batteries do and this doesn't, so if you get this battery you may have to pickup these M6 threaded post adapters. I didn't realize that until I got the old battery out and had already ordered this one. EXIDE makes a direct replacement that had the nub-style posts, but it was twice the price at $200. https://www.amazon.com/dp/B0BXX1M49K?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Saved a lot of money by buying this battery for my 19 Jeep Compass. Very easy to install. Working as it should.

Worked like a charm and installed with no problems. Electonics on the car lit up immediately. Satisfied customer!

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.

NOT for B200 Turbo made before 2011
