On the right of the pic is a Franco make torch which came with its original battery. I presume my other torch uses the same shape battery but smaller. I built a holder for two AAAS which I had to modify and all is well with this but my new torch is smaller and more of a challenge. An AAA holder will not fit so I tried joining together two AAA cells in series and used some brass strips for the terminals which I think the original battery had but try getting the size right and the fit, frustrated is how I feel now but may try size N cells but there to short. The problem is the terminals and getting these right, its to fiddly so may not bother. Not a great loss at two quid as the torch is mint condition. With a holder it would have been better but it wont fit.
The problem is this torch is smaller than my Franco one and space is very tight, the switch presses against a strip terminal of the battery, that's the hard part. I tried two AA cells but no room for those strip terminals.
