Abstract
Rechargeable battery packs include one or more key slots along a rear edge in order to distinguish it from other battery pack types and rectangular guide tabs to be backward compatible with former battery pack chargers and former battery operated devices. Battery pack chargers include one or more key tabs in a door and rectangular guide tabs to differentiate rechargeable battery packs that can be safely charged. Door closure switches on a safety switch to activate safe charging of a rechargeable battery pack with matching one or more key slots. The one or more key tabs and the one or more key slots provide a safety mechanism to distinguish rechargeable battery packs which can be safely charged. Rectangular guide tabs on sidewalls of an inner housing allow rectangular guide tabs of the rechargeable battery packs to slide under and further differentiates those that can be safely charged.

80. (Original) A method of constructing a rechargeable battery pack, the method comprising:
-
forming a top half and a bottom half of a battery pack housing, the battery pack housing having an opening in a front side to allow insertion of a temperature probe, and a pair of openings on a right and left side to allow protrusion of a pair of contact terminals, the bottom half having a pair of rectangular guide tabs near a front side on the left and right sides to couple the rechargeable battery pack into a battery pack charger or a battery powered device;
coupling a plurality of rechargeable batteries in series together, a first rechargeable battery of the series having a terminal coupled to one of the pair of contact terminals, a last rechargeable battery of the series having an opposite terminal coupled to the other one of the pair of contact terminals;
inserting the plurality of rechargeable batteries into the battery pack housing so that the terminal casing of the first rechargeable battery of the series is contactable by a temperature probe through the opening in the front side of the battery pack housing and the pair of contact terminals protrude through the pair of openings on the left and right side; and
fusing the top half and the bottom half of the battery pack housing together to hold the plurality of rechargeable batteries coupled in series together within the rechargeable battery pack. - View Dependent Claims (81, 82, 83, 84, 85)

102. (New) A rechargeable battery pack comprising:
-
a plurality of batteries coupled in series to generate electrical capacity for a battery powered device and to receive a charging current from a charger;
a top half case and a bottom half case coupled together to form a battery pack housing around the plurality of batteries, the top half case including one or more key slots configured to distinguish the rechargeable battery pack from other rechargeable battery packs;
a left rectangular guide tab coupled to a left side of the bottom half case, the left rectangular guide tab to guide the rechargeable battery pack into a battery powered device or a charger; and
a right rectangular guide tab coupled to a right side of the bottom half case, the right rectangular guide tab to guide the rechargeable battery pack into a battery powered device or a charger. - View Dependent Claims (103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123)
