After about 4 years, my NEST is now going to low battery and disconnecting from WiFi. I can recharge with usb but doesn't seem to be charging on the wall. Nothing has changed in my home. Can these rechargeable batteries be replaced? Could it be something else? It hasn't happen before. Maybe once after a power outage but never again. Any suggestions would be greatly appreciated.

How is the Nest wired?
Does it have a C wire installed?
The batteries are not replaceable.

You need to add a C wire if an extra wire goes to the furnace from the thermostat.
If there isn't and extra wire, you can use the Nest Power Connector to solve your problem.
