Sanyo Eneloops are 1.2V, Alkalines 1.5V, Energizer lithium @1.6V. Eneloops are the way to go for everyday usage. Perfectly fine to use in Maglites. I keep lithiums in the glove box flashlights and as backup. Alkalines don't go in any flashlight anymore and I even store them separately from other batteries. Yes, I've had new, unused alkalines leak.


FYI, if you can get the batteries out, distilled vinegar helps neutralize the alkaline battery goo.
