Using watt hours is like rating a toaster in mega calories.
The chemistry in those batteries is totally different than standard off-the-shelf Li-Ion. The vendor is ADAMANT that operating voltage is 1.5 not 1.2 volts. So a standard Li-Ion charger will not work. Perhaps a charger for rechargeable alkaline? I now have all the buckers I need so that would not be a problem.
A standard small battery is 3.7 volts.
I am looking for a diving headlamp for Jesús. Powerful. 3-hours of work time on the brightest setting and rechargeable batteries. Something that is worth less than my clunker car.
