Just wondering... why is it that LithIon batteries got three contacts?
Li-ion batteries if over charged or charged too rapidly can catch fire. The third contact is for the charger to monitor charging rate and charge state.
Maybe no-one likes them. Or they've only just opened their Facebook account and they haven't told their friends.
@jstuedle: Thanks for the useful, informative reply.
