This is a 20a cell
Do you know what the difference between the UR18650WX and UR18650W2 is? I’m wondering if my batteries ever go bad if I can steal the cells out of a B&D 20 max battery for cheaper.

and this…
**Abundant variety of models meet wide variety of uses(UR18650 series)
>F: High capacity with steady operating voltage model.
>E: High current model for power applications.
>Y and A: Cost performance and improved standard model by optimization of material.
: Cost performance and robust model by optimization of material.
>SA and W: Excellent power model for power tools by optimization of material and structure.
>U: Long storage life and high current model.
>ZT: Neo hybrid positive electrode enables higher charging voltage, which realizes further high capacity model.
so I’m guessing these SAX batteries are already putting 20A draws continuous. Although, now that I think about it, what would those ZT batteries do for the longevity of the flash light that use this batt. Pack? From what I have noticed, my flash light dies faster than my drill… well, I work in dark places and use the flash light mostly continuously… i’m guessing the flashlight does not need high power but more of high capacity batteries.
what if I upgrade one pack with ZTs for the flashlight and A123 APR18650M1 for the drill?
