Hi All - I have about a half dozen APC UPSs in the house - the largest one is connected to my iMac/modem/router (recent dual battery replacement); 2 smaller ones connected to my den electronics (2 older ones as potential backups) - the APC BU 550 has been intermittently clicking when I turn on my receiver in the morning (goes into sleep mode) - I can usually turn off the UPS and restart w/o a problem but lately needs a couple of power recycles - this morning I exchanged the UPS w/ another - I've read a half dozen threads on the web related to this issue and the main suggestions have been: 1) AC power dips (doubt an issue for me); 2) Battery needs changing (the UPS gives no sign of this need and I'm not sure 'how old' the battery is?); and 3) Battery charging circuitry in the UPS is malfunctioning?
Now at this size, these are inexpensive purchases, i.e. on Amazon an APC replacement is about $73 and the battery $30 (pic below) - I would just replace the battery to save 40+ bucks but if the 'clicking' is a malfunctioning unit, then not a solution. Would appreciate any comments - thanks. Dave
