At a 0.25A rating (assuming that is correct value for where it came from) it will be probably be the mains supply fuse.

From the events you have mentioned over the thread it's possible:- cutting through the hedge trimmer flex caused some transient on your mains popping the fuse, this allowed the battery to drain out until it failed in the early hours.

Best solution to stop that in the future is petrol or electric hedge trimmers, depending on what type and how much hedge you cut. Much safer and like most cordless stuff now you'd never go back to corded afterwards.

Thanks, totally agree on the cordless, we have chainsaw and strimmer- hedge-trimmer is in the legacy garden tool set. But the single best garden tool is the robot mower!

There were two small glass fuses side by side - not the main one on the incoming, both small fuses were 0.25a

be mindful to replace them with the correct sized quick blow fuses (if you don't intend to get an installer in & DIY it)

The fuses are sized to prevent damage or possible fire!

if this 0.25A fuse on the board id suggest its the wrong size

I'd agree

I thought it was a typo, or lack of understanding of current values the mains fuse would be higher than 250mA. I was right, Steve has confirmed that it is the PCB fuse which would not have been influenced by the hedge trimmer, unless she was trimming the carpet and caught the cables underneath or trimming around the bell box LOL
