Thank you for the info. I will look into that and set that up ASAP.

Regarding the battery age, I’m not too it’d but I’m guessing approx 3-4 years. You think it’d be worth replacing, in light of this issue? Run time still seems Ok ~45 mins, but maybe the load when it switches over to battery may be too much?
