The lockdown has killed my Sat Nav batteries, hardly being used for months means that even when fully charged as soon as power is disconnected the thing shuts down.
Normally not a problem, however it takes ages to re-start. I mean ages several minutes at least. Which if you are in a rush seems like forever. It also means that if the power is interrupted briefly it switches off, for example you go over a pot-hole and the plug works loose in the 12v power socket.
So after a few weeks of just shouting at the thing I did a quick google search for replacement batteries, ordered one & when it arrived today I fitted it. It was a bit of a fiddle as the internals on my G06000 seem to be different to all the others featured in the online videos, but 20 minutes later & it is all done. I have left it on charge & will let it charge overnight for the first cycle of the battery, hopefully this is the end of the saga.
Update: Given a long charge, have unplugged the power and it is still running an hour later, Yay!
