A CR1225 battery is 3V and its size is 12.5 mm diameter and 2.5 mm high.

I measured the battery holder on the CSGShop GPS as 6.8 mm wide and 2.1 mm high which suits a 364 size:
Lol, that means CSGShop was telling me bullshit.
Thanks for pointing that out.

The data sheet for the MAX-6Q lists backup battery voltage as 1.4-3.6 V with 22 uA typical current draw at 1.8 V. The 364 was the best solution I could find.

I guess, if you could find a Lithium cell with the right size, you could use that too.
Not sure if it exists. According to wikipedia that size is called SR60
