Thanks. Tried your reset method but no joy. I will bin it.
The other one came good though :-D
Shan't bother replacing, if two of them have sat unused for a year I don't really need them both.
I have a Fenex E15 as my pocket torch and thought it must be time to charge it. It has a Fenix 16340 in it.
I have a couple of spare Nitecore RCR123s in my battery box (probably been there over a year) so I thought I would rotate them.
I tried both Nitecore batteries in the E15, one did...
I bought one of these a while back but not used it much. Went to fire it up today and nothing, battery is flat. It wasn't left turned on. Does anyone know if it had over-discharge protection built in, if not I might have goonered the battery...
