I bought this flashlight a few days ago. Either you can power it from the power supply or you can put "rechargeable batteries" in it. The problem is what kind of batteries!! I called the company and they don't know. And the manual has about 3 lines and doesn't mention the type of rechargeable batteries needed.
The best results I got so far is with rechargeable Alkaline batteries. I drained them to around .4V and was able to recharge them with the flashlight to 1.1V but at 1.1V that's around %20 less power than with the power supply or non-rechargeable alkaline batteries. How come I cannot recharge them to 1.5V? I've attached some pix (the black strips on the flashlight is just grip tape since the case is very slippery).
