Battery pack with capacity and pre-removal indicators

An electronic device capable of receiving power from a battery pack, the electronic device comprising:

• a slot;
• and
• a battery pack disposed in the slot, the battery pack comprising:
• a housing;
• a rechargeable battery disposed in the housing;
• a battery pack disposed in the slot, the battery pack comprising:
• a housing;
• a rechargeable battery disposed in the housing;
• and
• a contact disposed on the housing for coupling to the electronic device when the battery pack is inserted into the slot, the contact providing a pre-removal indication when the battery pack is being removed from the slot;
• wherein the contact on the housing further comprises three contacts, the first and second contacts engagingly coupling with the electronic device to deliver power to the electronic device and the third contact engagingly coupling with the electronic device such that during the process of removing the battery pack from the electronic device the third contact enables delivery of a pre-removal indication prior to the uncoupling of the first and second contacts from the electronic device.
