i have a number of blackdiamond lamps and have always enjoyed them. One thing to note alkaline batteries have 1.5v and the light will operate at highest rating. Rechargeables only have 1.2v and will operate accordingly less lumins with the reduced voltage. So far I have had to warranty 2 revolts the issue has been poor quality batteries. I'm a battery nut and have a couple special chargers. That can measure, charge and discharge one cell. As all other budget charges operate in pairs. To date I have had a cell fail each time and discharge the pack. Leaving me stranded which is disappointing. ** please note light is not waterproof and will not take other types of rechargeables. Unless you google how to hack the replacement batteries. ** Price is reasonable online cheapest is 49.99 mooseJaw, last I saw rei had them clearance but show nothing online.

camshaft1.2v is a nominal rating and after charging most will have 1.3 to 1.4 volts that drains off rather soon. I've found that high quality rechargables will lose a little initial brightness, but they keep a higher level of brightness over the life of the battery, especially during the most useful portion of the power curve. Alkalines drop off more sharply under drain, so you get a tad more initial brightness but noticeably less during the next few hours of use (on high/higher settings). Curious about your statement of not being able to use other brands of rechargeables in the Revolt. I had my Imedions in one just fine and a friend ran her Eneloops in hers for a long time until the charging port got zapped by rain and she had to warranty it.

Stepbystepwell it actually says on the back of the BD package that rechargeables have less output. Personally I have physically noticed the difference in brightness but dont have any equipment to graph the voltage underload. As many different brands of rechargeables exist as well alkaline or even lithium. As for my comment towards using nonBlackdiamond rechargeables and needing a hack. Google it. The revolt was designed to not be able to recharge a alkaline or non-blackdiamond battery physically. Inside the battery compartment the negative contacts to recharge touch the body not the normal -end spring. So any nonblackdiammind cell will lose the ability to get recharged via the charge port. With out hacking the replacement cells. Obviously if you have a external charger that can charge 3 cells at a time this doesn't effect you.

camshaftInteresting. I wonder if that was a running change regarding the charging and cells. Above, both of those were bought when they very first introduced the Revolt. Still a Spot for me, though...seems just a little more versatile overall.

Stepbystepwell the BD batteries have always had the special bare metal area "no paint or label" which allows the contacts to touch the exterior shell of the cell. Which on any other cell would insulate the charger tabs from touching, so that by accident a alkaline cell wouldn't be charged. So that obviously bad things don't happen when alkaline cells get charged.
I have attached some images and you can see round silver tabs under were the batteries have shinny metal area with no label.

camshaftJust now saw your reply here. Yeah, that's correct about charging via the port. I thought you were saying above that other batteries would not work at all in the lamp, making it proprietary (which I guess it is, partially, in regard to charging in-lamp).
