Anyone who has used rechargeables knows they eventually die.
They start out with umpteen thousand mAh [milli-Amphere hours], and
they get weaker and weaker as the months go by until one day the GPS
quits in the middle of a long hike when you're really counting on it.

I wish someone would sell a battery capacity meter. You'd stick a
battery in it, and it would put a typical electical load on the
battery and run it flat at which time the metter would beep and show
the battery's current capacity in mAh.

Lots of applications: Know when it's time to replace a battery.
Match batteries of similar capacity. Identify defective bateries when
you buy them. Etc.

Anybody know if such a device exists?
