K3 Batteries and other questions

There was a change in the battery about 2 years ago with the addition of an extra contact (was three now four as I recall). The claim was that it better grounded the battery and brought it into compliance with an EEC mandate of some sort (also upped the price incidentally). I have each kind in my kit and can find no difference between the old and new versions of the same battery.

The cameras only have two contacts internally. The extra contacts may be used by smart chargers.

Haven't cracked one myself, thought there might be a chip inside for the extra contacts.

Here are pictures of the K-3 and K-5 battery bays.
There are only two contacts, one meets the - terminal on the battery and the other meets the + terminal on the battery.
There are no contacts at the camera for the 3rd or 4th battery terminals.
