Can one undo the EPS controller connector and its earth or do you need STAR to reconfigure it ?

but you can't dump a huge amount of current into a lead acid that easily.

(as I'm positive you already know) its supposed to be an AGM, which can take more abuse in and out

AGM battery internal resistance can be up to 1/5th that of a flooded lead acid battery so in theory it can be charged up to 5 times faster and deliver 5 times more current. In practise it's less than that - more typically 2 to 3 times.

For sure, including relatively deep discharge without damage and long periods of time without self discharge.

I just bought a new one for the S class, lets see if grange mouth supply the right one (95ah AGM). They where £30 cheaper than the cheapest Yuasa I could find.

I have a 30AH AGM motobatt on the diesel bike, that sat without being charged for a year and half, and still had 12.5V when I checked it.

Yep 80% discharge against 50% for flooded cells.

whitey and I both got the right one from them in last few months (an utter steal)

The subframe bushes where also cheaper than Febi equivalents on ebay

Hmm I tried to get a 95AH to replace this one


and was told they have been superceded by the 92AH like this Below


The 92 AH is the one ... well two that are defective.
Was the first your current part no.?


Maybe yours is a physically bigger bay.

So very interested if you can get one.

In that location I doubt the 95AH one will fit, looks like its a good 4 to 6 inches longer.
You have the later, single battery system under the bonnet?

Yep its the later single battery version.
It used to be 95AH .. but was replaced by a 92AH of the same size.
They said there was a 105AH but thats longer and definitely no room to carry a bigger battery. The gap here is the width of the dual cables plus 5-10mm max.

the big 95 amp hour battery that's std in the back of my w221 S class and the back of my fathers w211 e class is

350mm long x 175mm wide x 190mm high
between terminals its 295mm centre to centre and weighs 26kg

Thats the one, now discontinued in fsvour of a Same sized 92AH.
The next one up is a 105 AH, but its 394 mm long

do you really think that (350mm long x 175mm wide x 190mm high) would have gone under the bonnet on your car ? mine in that position is about 200mm long, whilst there's a good few inches for a bigger battery, don't think that one would go there

Yes, The current one is 353 x 175 x 190mm and thats as big as it could be. And its a very tight fit!
