These batteries have an VERY POOR charge! Some last less than 24 hours! AND they arrived in childproof packaging which I did not order! I have no children in my home. The batteries are difficult to open. In order to open I have to use scissors which is not convenient if I’m not home?! I should have returned but now it is too late. Do not order!3.13.25 UPDATE! LEARN FROM MY $ LOSS! These batteries are just fine; the problem was me. Yes, it is true they are in child resistant packaging which is horrible, but evidently there was a law passed requiring the packaging due to a child swallowing batteries and dying. What I don’t understand is why we can choose to not have child resistant Rx bottles but we can’t choose to not have child resistant battery packaging. Anyway, because the packaging is so difficult to open I opened a lot of packages and put the batteries in a jar for easy access. Well, through a lot of experiments I finally discovered if batteries touch other batteries the power is drained so I might have well tossed ? in the trash ?????. I’ve used hearing aid or CI batteries for MANY years and I never knew this ??‍♀️. Of course there was never the need to open the old packaging I miss and didn’t appreciate until they are gone.
