My ancient Oldham T2 battery is in need of service; has anyone got a spare 'key' for the end to release the top? or alternatively know where they can be obtained. Also I would like a key for releasing the pin on the head-lamp housing,
Thanks, Nick.

I used a Dremel drill with a grinding disc to cut a groove in a flat blade screwdriver.

I am sure by now you will have been told that you can hacksaw the pin off the head lamp, using a small saw.
You can then screw off the bezel.
This pin as I understand it was put in place to prevent coal miners, adapting the headlamps, to run through resistance wire, which then could be used to light fags!
As you are not going to do any of this the pin is not necessary.

Most likely a different fitting. Older G type used a pin with a triangular head. More recent G type (and yes you can still get them!) and D type use an Allen screw.

A small long nosed pliers will undo the battery lid screw or, if you don't mind sawing the tube that surrounds the screw cut down the tube until the hacksaw cuts a slot in the securing screw.
Perhaps a 6 sided or bi-hexagon socket will fit the bezel pin, (if they make them that small).

Edit: I suppose one could grind/file an old screwdriver for the battery lid.

What I did for a battery lid tool was just to angle grind a notch into an old flat head screwdriver.

Thanks lads for the suggestions; I'm going to 'adapt' a flat-blade screwdriver for the battery, so that's sorted. I've had the offer of a loan for the headlamp triangular key, which is great but, if anyone has one to spare, I'd like to have one to keep,

The ground-out hex bit proved a great success & the T2 battery is responding well BUT, like an idiot, I forgot to strap out the fuse before connecting the 'blaster' charger! I've put in a car fuse holder in place as a 'fix' but, in the long term I'd like to put the battery back to full original spec so, has anyone got a spare legit/proper fuse link they can spare.

As an aside, to those who aren't familiar with these batteries, it's a brick shaped porcelain thing a little smaller than a LEGO brick.
Cheers, Nick

I still have loads of Oldham bits lying around and could probably put my hand on fuses of the normal type as well as the later poly self resetting type.

I once had someone''s lamp in for repair and they told me that they had a ''Petzl Duo'' that they could use. I didn''t sleep well that night and got up early to finish their lamp.

Hello Roy,
If you can lay your hands on an original fuse, I'd appreciate one next time you're up our way please! Thanks for any help, Colin.
