Hi folks,

I am struggling to find the original RS battery dimensions, having bought an RS in pieces the battery is missing so I cant measure it to find a replacement that will fit exactly.

Thanks FrustratedRS

Hallo!

The only size you need is the length up to 181mm for ALL Ks, (175mm is standard) the rest will fit anyway.
A modern non acid batterie is always slimmer.

If you are more interested just search in eBay for K75 100 batterie.
My has 18amp and the price was 36€! is from the solar industry.
Lead flowing Battery 181x76x167mm, no more dripping :-)
With acid batteries you only have problems, dripping, maintenance etc.

Cheers

Thank you chocolate,

Seems Confused is the correct username for me after all Smile

The issue on length and width. You give the width as 181mm (175 Being standard )

The 181x76x167mm, am I correct in assuming that length is longer than width? which means 181 is the length and 167 is the width or the height?

Thanks Smile

You are correct, I did a mistake!

My Batterie
Lenght 181x width 76x hight 167mm


I guess the width can be more than double, there is a lot of free space left.

I use a Motobatt MBTX30U which is L 166mm x W 126mm x H175mm.  It's a sealed AGM type so wont leak.  The height is about 5mm higher than standard for the K1100, K100 & K75 they also use a smaller battery which is the one Choco said.  5mm higher is very marginal on the screw length and is very difficult so I use some 6mm threaded rod and lock nuts at the base and nylocs at the top.

If the shops you're searching have cross reference charts, the OEM battery numbers are: full sized lead/acid 61 21 1 459 650. Slimmer sized Gel 61 21 2 346 800. Both will fit K battery trays. The la flaca (slim) version is 19Amp while the L/A el gordo (fatty) is 30Amp.

Other numbers to search for are the 'industry standard numbers' which are 51814 or 51913. In my Aussie RS I use Motobatt's excellent, yellow AGM version of either of these two reference numbers. Its dimensions are: L 183mm (7.2"), W 80mm (3.15"), H 170mm (6.69")

Just found a picture of The Batterie tray.
The Kung Long Batterie is a inexpensive non acid batterie.

WP 18-12, 12 Volt, 18 Ah, 167X180X75mm

34.99 US Dollar (eBay South Africa) that's even cheaper then in Germany
http://www.ebay.com/itm/Kung-Long-WP18-12-12V-18Ah-UPS-Battery-/281342287045?hash=item41814e9cc5:g:jGsAAOSw-jhULdM5

You will find better for the Ks, but nothing as cheap and good as the Kung long batterie! :-)

Here you can see the batterie tray in black on the gearbox

I don't have any dimensions at the moment but caution you on the height of the battery. At one end of the top bracket that holds the battery in place is a small concave indent that also helps secure the radiator expansion bottle. If the battery is even a little bit higher than the original equipment then two things may happen:
1. The long screws inserted in the top metal battery bracket and that thread into the battery tray may be too short.
2. The top of the radiator expansion bottle will not fit snugly into the indent of the bottom of the top bracket that holds the battery in place.
There are workarounds for both of these issues, one being longer threaded rod to replace the existing long threaded battery bolts (already mentioned) . You can also slightly bend the top battery bracket down to catch and secure the top of the radiator expansion bottle.

Thanks to everyone I have narrowed it down to a few suppliers in Cape Town Smile

I only have one more dilemma, since I don't have the original battery I have no idea which side the positive terminal has to be or does this not matter?

Much appreciated....

Terminal type and orientation matter.  Positive on the left side of the bike facing forward; negative on the right.

The black bump is the position of the drainage hole on a wet cell battery, but if you buy an enclosed battery, this will be missing.

further to Shep's suggestions on how to secure your coolant expansion tack , I fitted an Odyssey PC680 AGM battery , to help secure the tank the suggestion was to simply flip the battery bracket over ( and refit the rubber do dad from the reverse side ) this moved everything about 5mm down ( suggestion was from BMW owners of America site )

hope this helps
