1. An apparatus comprising:
a battery housing configured to house multiple batteries, the battery housing comprising a connector configured to provide current to a device, a surface of the battery housing forming a plurality of slots, each slot configured to receive at least one of the batteries; and a plurality of switches, each switch associated with one of the slots and configured to:
when at least one of the batteries is present in the associated slot, allow current from the at least one battery to flow to the connector; andwhen the associated slot is empty, pass current through the associated slot; wherein the plurality of switches includes at least one switch that is a spring-loaded mechanical shorting lever switch comprising a lever pivotable about a fulcrum, a spring, and a contact, wherein the fulcrum, the spring, and the contact are disposed on a same surface of the lever; wherein, when the slot associated with the spring-loaded mechanical shorting lever switch is empty, a decompression force of the spring against the lever and against the housing causes the contact and the battery housing to physically touch and electrically short together; and wherein, when at least one of the batteries is present in the slot associated with the spring-loaded mechanical shorting lever switch, the at least one battery and the lever physically separate the contact from the battery housing to open the spring-loaded mechanical shorting lever switch by compressing the spring. |
