Gadget to extend battery life

[Taffycat]

A new $2.50 battery sleeve called the Batteriser.... promises to extend the life of your batteries up to eight times longer by drawing out their remaining power.

AA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up. Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.

Batteriser can continue to deliver a 1.5 volt charge from batteries that have actually discharged down to 0.6 volts.

I had no idea about those figures, that's really surprising. Nice find

Interesting stuff... I know they do similar things with power tool batteries to optimise their usage, I'll be damn impressed if this little booster circuit works as well as it suggests!

Wow, sounds great but is it just too good to be true?

Suppose only time will tell. If it works then we'll all be using them.
