OK, so here is a challenge for the students out there. No fair if you've left High School...

Given the claims of the Battery Beak, design experiments to verify that it really works. Claims include:

Determines battery State of Charge
Determines battery internal resistance
Labels the battery good, fair or bad
Provides results in a second or so
Surface charge dissipates in 15 minutes at a slow (<6A) charge rate
>all assuming a standard FRC battery at room temperature

Pick one or more of these claims and figure out how to verify it.

Any takers?
