which one do I need ?

I think the best way is to buy a rubber battery box that looks like the original batteries for that time and then purchase a modern 6 volt bike battery that just fits inside. The size of the original batteries were pretty well standard across the range, one size fits all. I don't think it matters what capacity the modern battery is as you are only running a couple of lights and a horn and output from generator is usually only 3 to 4 amps. Lucas make the lookalike battery boxes with LUCAS written on the side and should look authentic enough. That way the terminals are hidden and looks very tidy.

I use reproduction 'dummy' WD batteries on mine and just fit a 5amp cyclon dry cell battery inside. No acid, no corrosion and they last for years.



I buy the Cyclon's from Mick Ash at the jumbles for £20 (contact details on request)

Here is my original Lucas WD battery that has been used for molding some of the repro boxes. Ron

First impressions are that you might be onto a nice little earner there Ron. Though of course I don't know how labour intensive making them is.

Hello all!

i'm the "french"supplier and maker of the dummy batteries boxes on the Ron picture( but i'm not the only one), for those who want some, contact me of forum please .
i could make batteries from 1939 to 1944.

My M21 came with a Goff fibreglass battery. It was dud. A replacement of the same type lasted three weeks. I replaced that with a lead acid inside the old box. That's worked ok. Yes I insulate them from the vibration and no Goff wasn't selling them anymore the last time I looked...

Has Arnaud stopped making these boxes ? It’s very unclear these times

My last “spare” - on loan to someone else - parted company with his bike & threw it self under a truck leaving the ferry port at Rosslare
An original lid also met its end

I wouldn’t mind another box or 2 to cover such occasional disasters

I'm only getting spasmodic response from Arnaud in the last couple of years. He's had personal and health and work issues and poor internet connection in rural France. I live in hope though. Ron

I passed on my 'WD' moulds etc. to someone else as I'm now retired..Theoretically the boxes will become available again from the 'new man'..However, despite making all the arrangements new boxes seem to be a long time coming...I'll see if I can get an update...
Regarding battery capacity if you intend to use a bike much at night an amp hour rating of nearer 11 amp hours will reduce the tendency to over work the dynamo....Ian
