Just got two of the new 16340 batteries from Fenix with the built-in charging circuit. There's a light on the top that glows red when the batteries charging and turns green when it's finished charging. Which is kinda neat. Took about 1hr 15 min's to charge after I opened the package, don't know how low it was. It fits in a Sanwu Guardian with no spacer or battery magnet. It a little loose, but not real bad. Thinking the spring will keep it firm in the host so it wont move around. Will update this thread in the future after I've run through a couple of charging sessions. Have a decent idea of how long a 18350 battery lasts ( a good quality one ), will take a stab at the comparison time. ( a guess-ta-ment ). Think these may work real well for the EDC's when you don't want to carry a battery charger around with you. Just using my Iphone's micro-usb cable and charger. It recommends .5 of an amp, max 1.0 amp input. here's some pictures you can check out. :)![]()
