One of my relatives still has a Trimble GPS he used to measure fields, bundled with perfectly working Internet disconnected software. However, I can't find the Li-ion battery replacement for it so I gave him my >10y old Garmin eTrex device which uses AA batteries and still works fine. I was surprised that the old GPS layer was kept running.
Regarding phones, there'salso third party firmware like LineageOS.

- throwaway81523 5y agoFind a battery of the same size or a little smaller and put it in. batteryjunction.com has a big selection. You might have to solder some wires on or similar. Adafruit.com has some with JST connectors which have a good chance of being what your GPS uses inside, but they don't have that wide a selection of cell sizes, so it's iffy. Anyway the first thing to do is open up your GPS and look at the cell. In the old days you could usually find a phone battery the right size on places like dx.com, but replacement phone batteries aren't that common any more.
