Additionally, any circuit that is charging a battery might cycle at this
rate, such as a cell phone charger, wireless telephone handset in its
cradle, or possibly a laptop charging its batteries.

Heaters in a fish tank might cycle at this rate. A small countertop oven
would also have a short cycle time. Some kind of device that has a "keep
alive" circuit in it might also cycle at this rate. Good luck.
