The technology described in this document can be embodied in a method of using a silver-zinc rechargeable battery to power a device. The method includes drawing, in a first mode of operation of a power management circuit, a first current from the battery to power the device. The first current is selected such that a target percentage of a capacity of the battery is discharged in a predetermined time of use of the device. The method also includes switching to a second mode of operation after the target percentage of the capacity of the battery is discharged. In the second mode of operation, a second current is drawn from the battery, wherein the second current is less than the first current. The method further includes powering the device using the second current.

Dual zone discharge of rechargeable batteries

A method is provided for making a synthetic jet ejector. The method comprises (a) providing first and second voice coil bodies () having first and second sets of channels defined therein, respectively; (b) inserting first and second sets of electrically conductive terminals () into the first and second sets of channels, respectively; (c) wrapping first and second coils of wire () around said first and second voice coil bodies, respectively, such that the first coil is in electrical contact with the first set of terminals and such that the second coil is in electrical contact with the second set of terminals; (d) forming a voice coil subassembly by attaching first and second ends of a flexible, electrically conductive connector () to said first and second voice coil bodies, respectively, wherein the first end of the connector is attached such that it is in electrical contact with the first set of terminals, and wherein the second end of the connector is attached such that it is in electrical contact with the second set of terminals; and (e) incorporating the voice coil subassembly into a synthetic jet ejector () having first and second voice coils such that said first coil forms a portion of said first voice coil, and such that said second coil forms a portion of said second voice coil.
