My old Led Lenser head torch is refusing to charge properly. The battery pack is (I presume) on it's last legs.
The numbers on the pack are ICR18650 2S1P 7.4V 2200mAh.
I went to buy a new battery but they seem to be obsolete. I can find similar battery packs but with different connectors; the Led Lenser has three connectors on one end labelled - - +
I suspect that it's just two Li-ion cells with some wiring and maybe some circuitry inside but I'm a bit loath to cut it open when there's still some life in it.
Does anyone have any advice?
