absoltively: slavin batteries i bought 4 and will be back for more. close to a full watt-hour.. i think i'll be able to run a light at .75W for about 70 minutes.
I might have to give them a shout. My pack in my phone is going out. it's 3xAAA NiMH cells. actually says so on the pack. "NiMH 600maH, 3.6v" or something, so i need to get 3 cheap NiMH AAA's. Dont wanna throw my Maha 800's in there.
I built mine.. there is a great thread in 'batteries included' that describes how.. there is another one that shows how to charge w/o a 'charger' per-say.... you can also buy an 'official' charger from slavin4u.com
