Systems and methods for storing batteries

A battery storage system, comprising:

• a plurality of batteries;
• and
• a battery holding apparatus configured to hold and discharge the plurality of batteries to reduce charge levels of the plurality of batteries, the battery holding apparatus having a plurality of slots, each of the plurality of slots for receiving a respective one of the plurality of batteries or a device containing a respective one of the plurality of batteries, the battery holding apparatus having a temperature control device and circuitry electrically connected to at least one of the plurality of batteries, the circuitry configured to drive the temperature control device with power from discharging the at least one of the plurality of batteries, wherein the temperature control device is configured to control a temperature of one or more of the plurality of batteries, wherein each of the plurality of slots is associated with a respective one of a plurality of output devices, and wherein the circuitry is configured to sense a charge level of each of the plurality of batteries and to control the plurality of output devices such that each of the plurality of output devices indicates the sensed charge level of the respective one of the plurality of batteries inserted into the associated slot or contained by the device inserted into the associated slot.
