[W126 Coupe] Battery

[Jay Hirsch]

Batteries unlike children should be seen   and not heard

Battery in trunk is poor engineering.  Not enough  space upfront  due to   "smaller car design"

>> Lead acid batteries are old technology and I won't buy them for anything but a low budget beater. AGM is the only way to go these days and that is all I will put in any of my Mercs.

>> I've spent way too much time and money over the years replacing corroded battery trays etc. In the case of my CL55, the damn lead acid battery leaked and dissolved the plastic housing of the power trunk pump that Benz conveniently located under the battery. Oh yeah, you can't just buy the plastic reservoir either- You need to buy a new pump.

>> Honestly, for what these cars cost new, you'd think AGM batteries would be standard equipment- Especially if you're gonna hide them in the trunk above a bunch of other pricey components that don't take too kindly to sulfuric acid.

>> With that said, in my option the Optima is they are crap as well.

>> Their goofy 'six-pack' construction and non-standard post location make them more of a pain than they are worth to try and shoe horn into the car.

>> I only purchase the Deka Group 49 AGM batteries for my Mercs now.

>> The look and fit like the OEM lead acid batteries and the posts are in the proper location so you don't have to rig the tray or cables to make them fit.

>> Sure, they cost $185, but they are zero maintenance and exact fit replacements.

>> 

>> IMO, the only thing a lead acid battery is good for is if you are doing a concourse restoration and it must be original down to the choice of battery.
