I had two spare Lezyne batteries, but they got properly wet when I got caught up in a massive rain some time ago (I forgot they were unprotected in a rucksack...) 😳
The light takes these: [img]

Would it work with some of these? [img]

The sizes are identical.
However the Lezyne one is 600 mAh, 3.7V, 2Amp (rechargeable).
Duracel: 3V, 1400mAh.
I need some spare for a night ride tonight (hopefully!)... Thanks!
Have you compared the spec with the rechargeable batteries that come with exposure flash and flares, look very similar...
They should work fine but the light won't be quite as bright but will run twice as long. Exposure use the same batteries in their flash/flare lights and they used to have a comparison between running on disposable and recharchables. I can't find it on their site but it was sothething like 100 lumens rather than 120 lumens.
Many thanks! 8)
