Have you got the part number for that battery?


Oddly enough, I don't think I could install that anyway. My battery bracket crosses the top of the battery and secures with 2 wingnuts. So I assume a "flat-top" battery is what I'd need.

The correct hardware for mounting the battery in a W113 is what you see in John's picture, a square metal frame and two "J" hooks with M6 thread.
Measurement for the battery itself are width 170mm, length 260mm and height 200mm. Battery posts will add some height (222mm in all). Battery can't be too high, as this will interfere with the hood (bonnet).

Yes.  Replace the battery.

I found that the Energizer battery part# e36R with 810 cranking amps and 650 CCA fits perfect. You just need to grind the lip on the bottom of the battery that is for a hold down bracket off. Whats up with the cheap flimsy metal used on the battery tray. I ordered the Mercedes OEM replacement and it was thin junk. I used my mig welder and made reinforcements for where the hooks go that hold the battery in. I also reinforced the tray where it mounts. It really just bent up when any force was applied to the battery holddown. It now is rock steady and you can't see any modification from the top.

Not sure, it was in the car when I bought it.

It's a shame Mercedes doesn't offer a dry battery.

I have an off the shelf Optima Red top in my car.  I used the kind of aftermarket hold down that Paul and James have.  There are no clearance or vibration problems, and NO starting problems.  It isn't original, just practical.

The Optima 34R comes with a height adjuster and fits perfectly but its foot print is a little smaller.  To prevent side movement I put a bit of molding epoxy putty (Marine-Tex) in the 4 corners on the tray and painted it black.  My top bracket is different because of the added shut-off switch but has the same dimensions and J-bolts as the original.
No more worries about overfilling and/or leaking battery acid!

Installed an Optima today and now have a huge difference in the way the car starts up.  My old battery Astro Lite was installed in the car when I purchased it.  It lasted just over seven years.  http://www.fondyautoelectric.com/webpages/astrolite.html

Sears Die Hard International; lasted 8yrs, $75


Having a trickle charger, makes a huge diference in startup as well

I used to have the griots cut-off switch; and would need 3-5 cranks

The measurements given by Hans match those of the Mercedes battery, part number 003-541-33-01-26, which now lists for $232 (!!).  As given by various posts, the correct size code is 24F.  Checking specifications, I thought at first this would be too tall, but it turns out that Hans' height measurement does not include the battery posts, but the dimensions I found for size 24F all did.  

The dimensions do differ a bit from battery to battery.  For example (lincluding the battery posts).  

	Length (mm)	Width (mm)	Height (mm)	Length (in)	Width (in)	Height (in)
Orig:	260	170	222	10 1/4	6 11/16	8 3/4
BCI 24F:	273	173	229	10 3/4	6 13/16	9
Interstate:
MTP-24F	279	175	222	11	7 7/8	8 3/4
MT-24F or I-24F	260	175	222	10 1/4	7 7/8	8 3/4

BCI stands for Battery Council International

Can someone assist with a clearance issue.
My next task on my project is to manufacture a new battery carrier/holder, the original is 10 3/8 inches long and the modern battery that i would like to fit is the BCI 24F which is 10 3/4inches long.
Can someone measure there installation and inform me if i increase my new carrier to 10 3/4inches i will not have a clearance problem with something in that area.

Chris,

Thanks for the measurements!!  I'm buying a battery this weekend and will print these and take them along with me.  I'm replacing a DieHard that was in the car when I bought it almost 9 years ago, so 'll probably get another DieHard.
