Since I'm using 3 AAA battery's in these flashlights and in my head lamps, now I'm in the market for AA & AAA rechargeable battery's and charger, this flash runs 3, my head lamps run 3. So I'm thinking of getting a 6 slot re-charger that will charge AA & AAA and wont take 2 days to do it. I buy these non-recharging battery's to put in everything, then use a couple hrs. throw them out, seems like such a waste.
