Battery Amp-hour Capacity Tester
I bought some lithium ion rechargeable batteries a while back. I was planning on
using them to modify some solar powered LED spot lights. What I like about these
new batteries is that they are the same size as a standard 1.5v alkaline AA cell.
With such a package, I can use a standard AA battery holder. The battery
manufacturer claims an amp-hour capacity of 2.2 amp-hours. Usually, these
amp-hour figures are made using rather small loads, conducted over a long period
of time. ......
Faraday Switchesare tiny one inch cube
electronic modules using a capacitance change technique. They draw very low
current and are ideal for battery powered applications.
