Was getting an “e195 – no power to r detected” with my nest thermostat e when nothing had changed with my heating system and after some research online it was suggested that a bad battery could be the cause

Thus i got this to replace the battery and while it’s not an exact replacement this battery is slightly smaller it works

I also only used half the tape provided since this battery will need replacing in a few years and i wanted to make the replacement easier as there aren’t any pull tabs to easily remove the tape like with the original

After placing the nest e back on the base plate unfortunately the screen is no longer displaying so i have other issues to troubleshoot but i did confirm that the battery does in fact work and keeps power for a while even when removed from the baseplate

Its a pretty simple process to swap these batteries but if youre unfamiliar youll find all the steps in a 2 or 3 minutes video online

Getting out the old battery was a little tricky because it was glued in pretty good

So far the voltage is staying strong and we havent had to remove and charge the thermostat like we have been doing for the last 6 months

It came with a very small screwdriver which was needed because the screws were incredibly tiny
