Today saw a pair of Energisers, expired 2015, and only now starting to leak. Compared to the Durahells, expiring 2026, that were leaking in the packaging. I now am just buying cheap generic cells, around the price of a 4 pack of Durahell or Enermisers, but you get a 24 pack instead. Lower capacity, which means less pressure in them, and perfect for things like remotes and clocks.
Only thing I wish is to find out who makes the white sleeve no name batteries for Proctor and Gamble, never had any of those ever leak, even if they were a decade past the expiry date, they would still have charge in them if unused, and would never fail in equipment and leak. They were the batteries in Glade air fresheners, as I would buy the promo packs, which were 2 cans, the dispenser and the batteries, for less than the retail cost of a single can. Ladies wanted fresh loo smell, so went through 8 cans per month. Thus I had lots of those cells, and even more so the dispensers, which went straight into the scrap plastic pile, after taking the motor and board out.
