ebay has coin or button cell adapters, some hold two cells but one side can be jumped. The cell is less than a dollar and will last for years. LR-44 comes to mind. The lithium cell is 3 volts that maybe too high but they have a shelf life of at least 10 years, never, ever leak. The holder can be bus wired into the circuit even if it is for PC/surface mount. I did look for smaller cells but most of those holders are for several cells...
