Every light I've mentioned has removable batteries just like most non-magnetic recharging lights. I never charge the Wizard magnetically, as my external charger/tester does a far faster job and charges the cell more completely. When I've tested the Klarus cell right after charging, Klarus's magnetic charger seemed to do a perfect job of topping it off and rather quickly. But it's not like you can't remove the battery for external charging or testing in any of these lights. Who knows, they may even be using some of the same cells you're familiar with. I haven't unwrapped any myself, but I know Lumintop uses Panasonic cells they rewrap with their own Lumintop label. They even sell them separately for customers who don't mind paying a small premium or who don't trust most vendors, selling the plain green wrapped cells, to be selling genuine new product, rather than refurbs or knockoffs, which seems to plague vendors like amazon and ebay. I'd be a little surprised if Klarus and Armytek actually make the batteries they use in their lights. And for light models that implement some of the very latest, most powerful LEDs - which currently seems to go hand-in-hand with features like magnetic charging - the battery they built the light around probably isn't any kind of slouch. But, you can use other cells, if you prefer. If your preferred cell performs just as well as the factory cell, great. If it can't... well, that's about as good an indicator as I can think of that it might be time to consider a better cell.
