There goes my theory that rayovac was less likely to leak than energizer or duracell, well definitely better than DuraLeaks. Somebody on this forum said they had good luck with Panasonic zinc so I might try those for the few times I do use/need alkaline chemistry batteries.
I've found over the decades that ALL brands leak, I've not truly found any reason for what batteries do and don't leak as I've seen where All brands change their label/design of their batteries and they don't leak any less than the old design.
I do think that a part of increasingly leaking may be related to thickness of the battery container that is a foil/paper shell vs a steel type shell the steel seems to leak less but they still leak too much to be considered over the ones that leak more. I've found that the dollar store (now 1.25 store?) batteries leak about the same but do cost less but have no warranty on them when they do leak.
In the end my major concern is Rayovac over the years tends to be lower priced than Energizer and Duracell and now it is owned by Energizer in time will we see the Rayovac brand vanish entirely and its differing offerings of lights and lanterns also vanish and less lights that we have liked..... gone like the roughneck line etc. I think it has been about 2-3 years now that Rayovac has been absorbed and I'm not sure but I noticed there aren't many or even any rayovac light offerings in stores now if someone can correct me on that observation please do so as it is concerning that instead of gaining more from the buyout are we are essentially losing everything Rayovac is about. One could say did the Energizer borgs assimilate rayovac and now their unique product are no longer?
I've gone through liking all major brands over my lifetime from the old 9 lives cat batteries etc to almost every locally available brand offering in alkaleak and perhaps 1/3 to 1/2 of the heavy duty/carbon type batteries and to be honest none of them really stood out more than others enough to have me loyal to any of them.
I'm not sure but Dorcy is associated with Rayovac but it could be that they were bought out also not that most dorcy products aren't really thrilling to most folks these days. Even their plastic LED flashlights just seem way overpriced and underperforming as Dorcy simply held on to old 5mm tech and then 8/10mm tech to the point of which nobody cared about them any more. I do know that many dorcy products were relabeled and sold under Rayovac and Diehard labels in the past. As I don't see diehard offerings around much they did make batteries also.
