I'd like to see these now rated for leakage by monitoring, maybe even shorting half the sample. As far as I can tell, all cells now leak, while before it was some cells and aggravated with constant discharge.

Edit: Because I would like to know if I can trust any (other than rechargeable or perhaps Li) cells not to destroy my toys.

Eneloops don't leak and are my choice, even for clocks or remote controls. Using them for many years now, without leakage.

Not so sure about that amazon basics ranking. Pretty sure they are the same thing as a normal Duracell

I've noticed more and more devices specifying specific batteries -- e.g. my Spot tracker specifies Energizer L92s -- and it just makes sense that with these AA and AAA primary lithiums out there devices are taking advantage of them. Their open-circuit and under-load voltage is noticeably higher than an alkaline battery -- which is a nice efficiency improvement if you're boosting from one or two cells up to 5V -- and their leakage characteristics are in a different class.

Why don’t disposable batteries report their mAh like rechargeables do?
