My XML-T6 torch (18650 powered) is mis-behaving (won't stay on anything but flashing or very low power) on either of the two batteries I have for it.
I think it's symptomatic of the batteries being run down. Put them on the charger but the LED never seems to change from red (charging) to green (charging complete).... nor ddo the cells get at all warm. As I think it's unlikely both cells have failed in the same way at one & the same time, my suspicions are on the charger.
All this kit was bought over a year ago from Torchy (ebay seller big_f_d_d), so all Chinese, but seemingly all checked out by someone who knows what they about.
I sent him a message a few days ago via ebay, but no reply, and has he doesnt seem to be replenishing his stock these days he seems to be "off-line" in some manner.
Anyway ... my first thought is to spend a small number of £ on a new charger to try and resurrect the cells. Any recommendations? Or other thoughts?
