Rechargables in Jil 1.3w UP? and Kroll switch question

[Sproles]

I have a Jil 1.3w UP and would love to know if rechargables will work in this light. If so, which ones would I need? I am new to the recharable world and am about to order some 14500s for my new Jet Light that I have coming. Please advise...
Also, does the Kroll switch work on the Jil 13.w UP light? I cannot find anywhere where that is listed.

Many thanks!
