Alkaleaks are a bad investment as when 25% or more of them leak on you before expiration and another 25% of them leak barely a few years after that and another 25% leak after you have had them in a device and forgot about them 10 years later. Most of my leakers lately have measured close or more than 1.5v which means I pretty much lost 95% of the power in them to leaks vs usage.Ain't that the truth. Duracell alkaline's leak more than any other brand I've ever used. And I made sure I was buying them from a reputable dealer. I've had those cheap alkaline's that come with a TV remote last longer and never leak.
