While this probably wouldn't be as important to you but lithiums handle cold temperatures better...good for that flashlight in the car, weather station, trail cam, etc.If your device sits unused for long periods, use Lithium batteries. All my flashlights have Lithium batteries. The one's in vehicles go for years unused and last.

I checked them out a few days ago...Walmart has Energizers or Duracells cheaper than HF charges for these. Now maybe they're "just as good", maybe not, but I'm not willing to pay a premium for store brand batteries.Since they did away with the 20% off and other coupons they seem to have offered better pricing on their "better" Thunderbolt Edge batteries. I haven't really noticed if they are better since I no longer have a camera that uses AA. My wife uses them up mostly in her little fake candles.
