Answer:

Easy answer: Yes! Rechargeable batts are interchangeable with alkalines, regardless of the bulb type. There are drawbacks to rechargeables, though. They typically don’t hold a charge as long as alkalines do, so if your trip is longer than a few days, you’ll want to bring some portable power or solar recharging solutions (like the Brunton Restore, $124, ).

My favorite rechargables are USBCells, which plug directly into any USB port (no fussy, bulky charging docks to worry about). Check out our USBCells review

    Personally, I am not a big fan of the rechargables. They hold significantly less power than alkalines, and don’t give much warning when they die. These LED lights use so little power that the alkalines last a long time anyway. Or you could use lithium batteries, which are more expensive but hold twice the power of alkalines. The biggest problem with many lights (usually the ones with the infinite dimming feature and momentary touch switches) is that they are always on a little and the batteries run down if stored in the light.
