Besides being expensive, it's my understanding that 3v AA lithium batteries (half of a CRV3) do not have much capacity and/or worse yet, are not designed for high current draw. I don't think they're a good idea here. If this is incorrect, will someone please correct me.
There is more than 1 type of 3v AA Litium battery though. Should you unknowingly get a hold of these, Lithium Manganese Dioxide chemistry AA's made for Memory Back-up (MBU), who knows how this battery might react under high current draw. These, are designed for low current draw only. I'm not sure what chemistry is in all the CRV3s. :shrug:They perform like the 1.7V Lithium cells by Energizer. However they have more power. Capacity isn't everything, when you're comparing different voltage cells you have to take total power.
if I were to use the 14500's.What would be the best specific one to buy plus the best charger to use as welll....thanks Clipboard
get the ultrafire 138 that is the one for 14500s the 139 is designed for 18650s and may diminish the cells functional life
go with AW cells, thats what I use in my D10 and they function flawlessly
Also I thought about buying Ultrafire 14500 Protected Rechargeable Lithium Battery - 3.6 volt 900 mah and a wf-139 charger would these suffice? Clipboard
I don't know what those side terminals of the wf-139 do. I tested them for voltage, they appear to be NC.
