Core battery. It’s compatible with a lot of the Zipka and Tikka type head torches, and although it’s a touch mind-boggling to put in (you have to snap your torch in half!) it’s well worth the effort.
The most commendable aspect is you’re never sacrificing good quality light for a drawer full of half used batteries. I haven’t noticed any extra weight on my head, it’s plug-and-play, and a big saving if like me you’re using your head torch every week for 8 months of the year.
See you out there! Helen – Exeter shop
