S-T Headlite charging problems

My Speleo Technics Headlite will no longer charge. Everytime I plug the recharger in, the red LED flashes on for 4-5 secs then disappears, wiggling the plug gets it to return for a similar amount of times.

Any ideas why it isn't working?

I'm not familiar with the way the various chargers work, but for the benefit of anyone here who might be, could you give more information - type of charger, type of Headlite pack, etc?

Is the pack compeltely flat, or does it seem to work to some extent with a light attached (if so, suspicion might switch towards the charger).

Alternatively, is there any chance you could try charging your pack with anyone else's charger, and vice versa?

I found a Headlite charger (type HLC0001) in my spares crate. Looking inside, that particular design of charger is very simple, and if that's the type of charger you have, it isn't obvious where a charger fault could be that would cause the 4-5 seconds of LED lighting up to occur.

Mind you, it isn't immediately obvious what kind of battery fault would cause the symptoms you noted. Effectively, the way the charger *I* have in front of me works, the voltage across the battery would need to rise very high before the LED cut out, which would mean either a seriously damaged cell or a bad (high resistance) connection, either of which would very likely make the pack appear stone dead trying to run a light off it.

Does it work at all driving a light, and if not, did it die slowly when you last used it, or did it just cut out suddenly?
Had it been stored for a long time before you noticed it was dead?

If your charger is a type HLC0001, what happens if you short the output pins together for a few seconds - does the LED behave as before, or stay on as long as the short is present?
