It is common for a power tool system from a manufacturer to include a battery pack that is designed and configured to mate and operate with at least one power tool and a battery charger. However, as systems have evolved it has become desirable to provide a battery pack that is designed and configured to mate and operate with at least one power tool and a first battery charger but not a second battery charger. The present disclosure provides a battery pack including a housing, a terminal block, a plurality of terminals, and a mechanical lockout for allowing engagement with a power tool and a first battery charger while preventing engagement with a second battery charger.

Battery pack for cordless devices

A battery pack including a housing, a terminal block, a printed circuit board electrically connected to the terminal block, at least one battery cell, and a spark gap device on the printed circuit board to provide electrostatic discharge protection and disposed between the printed circuit board and the terminal block.

A method of charging a battery pack is provided. The method includes: electronically connecting a battery pack to a charger; detecting information regarding the battery pack; determining an appropriate charging regime based on the detected information; and applying the charging regime to the battery pack. A battery charger may also provided. The battery charger includes: a first terminal for connecting to a battery pack; a second terminal for connecting to a battery pack, a microprocessor operatively connected to the terminals and configured to receive a signal from at least one terminal regarding a battery pack connected to the terminal and control the charger to select and apply a charging regime to the battery pack according to the signal.

Battery pack chargers and charging method

A battery pack comprising a housing having an first housing portion and a second housing portion and an electrostatic discharge protection device to prevent electrostatic discharge from entering the housing.
