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

We used this battery as a cross referenced battery to fit in our 2022 chrysler pacifica. Works great without issue.

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.*
