Everstart Maxx at Walmart has 3 years free replacement and 9 years pro-rated warranty for less than $80. Everstart Maxx is made by Johnson Control the maker of Interstate and it is rated very highly by Consumer Report.

My next battery for '00 E430 will be Everstart Maxx.

I believe the Dealer battery has a higher CCA rating than the Autozone/walmart/sams club (johnson controls) batteries. Like 1100 vs 805 or something. That can make a difference on those -10F mornings!

AZ has the proper big unit for the W126s. My 300SEL came with a small batt, luckily for me it fits in my 745i turbo properly... so I just picked up another big MB one.

Got a Mercedes battery at Sun Motors in Harrisburg (Mechanicsburg), PA for $135. I didn't see anything much cheaper on Interstate's website or NAPA, so I went with it. Sure stands out in the engine bay
