Things That Go BEEEEEP In The Night..

Got woken up at 2am yesterday morning by a continuous beeping. Eventually tracked source down to UPS box. I suspect the battery is getting near to the end of its working life. I just wish it had picked a better time to tell me that.

Replacement battery arrived today, thank goodness. I can’t even remember when I bought the UPS, but it was more than five years ago I think.
