I give lithium cartridges top ratings. It is so much more convenient to slip in one cartridge rather than all those AA batteries. I have an old Gen 2. 0 camera and now a Gen3 camera. It is nice that the Gen3 battery will also power the old Gen 2. 0 camera. I have had the Gen 2 camera for almost two years and the original battery is still working with no problems. I like the longevity of the life of the cartridges. Thank you. A happy camper!
