I've been buying these batteries for years now. Not a single leak, not a single dead battery, nothing wrong at all. They last a long time, and are a decent value. On top of that, I look for them when they go on sale, which makes them an even better value.
I used to get rechargeable batteries, and then I started to do the math and realized how costly this got to be. It is also nice to have batteries with a long shelf life that can be there when the power is out, or whatever, without having to find the discharged rechargeables and then have to charge them.
So, you can buy these with confidence and without hesitation. I've been doing this with Best Buy branded batteries for years now.
