I stopped buying any brands that are not Energizer or Duracell years ago, just not worth the risk in my electronics. I agree with the other posters on the Lithium recommendation, you can store those things inside your devices for long periods of time with low risk of leaking and your device will just work when you turn it on. I have found this to be especially handy in my noise-cancelling headphones, I can go multiple trips before I need to change batteries and I always keep a couple in my bag with me. -Patrick
