W111 Battery size

Post by brycedunn » Sat 06 May, 2017 10:51 pm

What is everyone using as a battery size for a W111? I just installed a new battery, and am not particularly happy with the size so want to do all my research for next time.

The battery on there was an old NRMA DIN65. The size was pretty good, but it had recessed terminals meaning extra care needed to be taken to ensure the + cable didn't short on the battery hold down frame.

Image

It lasted pretty well, from 4/09 to now.

I tried a few different sizes, and in the end I got the one you see below:

Image

Its quite a bit smaller.
I was trying to find something that fitted better, but ones that looked good were a tiny bit too tall. The current DIN65 sizes now have a bigger bit sticking out for the breather (you can see this on the new one) so that didn't work either.

You can see the new battery is too short, so I've had to pack the bracket with washers and nuts. Its also not long enough.

Doing some quick measurements, the ideal battery is roughly 280 long, 170 wide, and 180 tall.

the battery I have in place is about 240 long, and has recessed terminals which is not ideal.

I think I need something close to a DIN65, but not quite, and not with recessed terminals.

Anyone found the perfect size?

Measure the old DIN65 and use it's measurements as a guide for the replacement battery.
Check out the size of an N70 (N70Z has reversed + and - connections so pick the one which suits your cable locations.) it is a 70AH battery so should be a little bit better than the DIN65.

Thanks, checked that out, looks like the N70 is 306 long, so would be too long in this case. Width looks good, but height could be a problem as its 225 high.

Interestingly I had the same batt brands and bought from the same overpriced retailer.

YUASA and actually many batt come in 2 height sizes. I think it was LMH and LM mark at the end of the DIN65 mark.

I had lower NRMA batt previously and the new taller one (YUASA) I got 5 months ago has 10% more CCA for the same 65Ah storage. Even better, it was mainteanance type so I can periodically top up the liquid and use it past the warranty period.

Judging from the picture you provided, that YUASA appears to me as if it is actually 53Ah

How did you go getting the frame around the vent ports?
I tried a similar battery and could not get the frame on (see picture with red circles)
The old NRMA did not have the bits that stick out.

Yes, its a 53. would have preferred something more like a 65, plus fitting better.

I typed the comment 3x and it failed to post because I use VPN... hence above comment is a 3rd abbreviation of what I said originally... and the part where I noted I was talking about my experience - not on W111 but rather C107. Sorry for that confusion.

See this Delcor Ag-Ca type:

R&J batteries stock them.
They have several different brands and models... you may want to go with your batt frame and see what fits.

In a Mercedes you have to put in a proper Mercedes battery :laughing6: ... here as big as possible:

Its been a few years, but last time I checked on the cost of a battery from the dealer here in Aus, I nearly fell over. It was at least 3x a regular one.

That's why they are rarely seen here, take a walk around all the Mercedes shows and you'll only need the fingers on one hand to count the number of Mercedes batteries. Even the car that won outright winner in the NSW Concours did not have an MBZ battery. How do I know? I went back and checked the photo I took of the engine bay, as it is a 220SE W111 cabriolet. Lovely car. Looks like it was a normal battery with the stickers carefully removed.

Technically, that would make it period incorrect, wouldn't it?

Yep, you're right. It's a pile of rubbish :laughing6: ... I even got new air in my tyres.

The reason why I bought a "Mercedes" battery was, I needed it urgently and that was the only spot I could get it on that day ... so just kidding!

Btw it's always handy to take that frame with you and test, if it fits the new battery. If you need my measurements (I mean the one of the battery :laughing6: ), I can take it for you

Thanks Thomas.
Is there any indication on the Mercedes battery who supplies it? I had always read that VARTA were the OEM for batteries, but I tried a number of VARTA batteries on the frame and none of them worked.

Thanks,
Bryce

Nope, the air was available at the time but pollution in it and the CO/CO2 content may need to be filtered to correct levels

Partly right, :laughing6:

I was born in Stuttgart and the air smells rather special there. So to make it absolutely correct, you should import ... ok let's stop that :notworthy:

I don't know, how aware you are of the German Mercedes scene ... but here there are people who come very close to "our discussion" when it comes to "originality".
My SL, e. g., has original Velours off factory and at a car show once I overheard someone saying "but that's not original" ... he was an expert obviously ...
