Same as my H9 Napa Gold AGM.

I had actually just replaced my battery before putting the car under the knife for the widebody work and although I left the body shop a Battery Tender to keep it plugged in when not actively working on it, they didn't and it was totally dead Lorre than once. When I got it back, I hooked it up to my Optima charger and the charging amps wouldn't drop down to a really low number and charger would never read past 75%. Took it to Napa and they tested it - said it was fine. I said no it isn't and explained why and they ordered me a new one - no charge, so when I finally got the car back I also got a brand new battery in it.

FYI, I found a Mercedes Battery on the shelf at work. pn# A0009821808 that appears to be a 105Ah 950cca H9 AGM battery. Apparently all our batteries are relabeled Interstates. The rep said I can get an Interstate labeled MTX-95R/H9 battery for $200.

Do yourself a favor and get an AGM. I am a huge fan of the DEKA 95R which is the H9 equivalent. https://www.eastpennmanufacturing.co...Flyer-1737.pdf

My battery died yesterday while getting fuel with the radio on. Just discovered and purchased a BMW 61-21-2-353-814 is an H9 AGM for $148.85+tax.
