> Can anyone suggest a head torch that holds removeable rechargeable batteries but not the AAA or AA type. Ideally one of those little stubby things about the size of a finger joint. RCR123A I believe. Never had a built in rechargeable that lasts more than a couple of years. Got bike lights like this and they are great.
A single CR123 rechargeable linits you to the option in Dell's post.
If you went for the 18650 battery (same length as 2 x CR123s) you'd get something much more useful in terms of output and burn time. 18650s have a very high output in terms of mAh.
I have a fenix hand torch running that type of battery and it's had a lot of use over a couple of years with no issues. Very bright and good burn time. Fenix do a headtorch version at about £75. It'll be solid and reliable.
BUT:
18650s are heavy, and because they're used by the vaping fraternity & have a fair bit of power, cheap versions that will burn your house to the ground are all over the place. A decent battery and mains charger from a reputable supplier will knock you back another £40. Plus it's another bit of stuff to clutter up the house.
As someone else posted, why not get a petzl or led lenser that charges off usb?
