purchased for 2017 Mercedes E220d. Battery was really good price and arrived very quickly (was well packaged too). Once fitted restored stop / start function and improved cold weather starting.
Excellent
I bought this battery based on reviews and wasn't disappointed. The stop/start hadn't worked on my car for about a year and other electric features seemed weak. I found this item here for the best price on the internet, Far cheaper than other places. Once installed within 5mins the stop/start was work, the car started quicker and better all-round very happy with the battery and service from battery group. Will definitely use again when I need another.

Fantastic product + price
Really pleased, good product at a reasonable price
I decided to go for this model battery instead of the budget or mid range options, as the price was reasonable, and I wanted a good quality, reliable product, with a good reputation. I installed the new battery effortlessly and has been in the car for over a week now, no issues at all, in fact I did notice my lights and dash appeared brighter than with the old factory fitted battery which had gone faulty with age. Time will tell if it was worth paying the extra. But at this price it was an easy decision. Also very swift delivery
