Ade Accenta G4 - Backup Battery Fault Mystery

Thank you all kindly for the input. Tomorrow I will try testing the batt voltage, while still installed, and after cutting the mains (with the flick of a switch rather than than the lethal grasp of scissors!)

 

If it falls then we have a bad battery. If it sustains around 12v then we have a bad panel. Is that the right thinking?

 

Thanks!


PS, Will check the fuse too - thanks for the tip.

It was indeed a dead battery!

I bought and installed a new AB21, switched off the mains (didn't even let the battery 'settle in') and no alarm bells rang.

 

Sadly my circuit tester had broken so I took the gamble, based on your consensus, and paid for the new battery. Well worth it!

 

Thanks for all the help everyone. Very much appreciated.
