Re: wearcomp batteries

there's 3 terminals, one's +, the other's -, and the one in the middle
(but to one side) is "info" (serial data).

the "info" (serial data) is what allows a compatible camcorder
to tell how much battery life remains, etc..

that's why theyre' called "InfoLithium batteries".

the + and - are mini banana female connectors, and the "info" is just
a metal strip on the case.

their original prototypes (the ones they donated to me before they
put li ion on the market) had 5 female banana connectors,
+, -, and the usual T, D, and C (temp, data, and clock) interface.

the original prototypes were, in my opinion better, but never seemed
to make it to market.
