CS 650 APC - changed 2 new RBC2 batteries but the UPS still Beeps.?

This question was originally posted by Bryan on APC forums on 8/6/2015


Hi Friends

I have replaced a New APC RBC2 Battery in a CS 650 APC unit and put it on Charge for over 24 Hours and still it Beeps - 1 Short beep followed by 2 or 3 double Beeps and a flashing red Replace Battery light.frown

I have lowered the sensitivity on the CS650 by holding in the Power button for 10 Seconds and getting all 4 lights on and setting level to 1 light (first on battery light).

I have a number of CS 650 units that are a few years old and have worked without any issues but as the APC batterys are not cheap, if I cannot resolve this Issue it may be cheaper to replace the unit altogether with a cheaper brand?.

Please helpembarassed

Bryan.

Update

I have bought and installed a second battery APC RBC2 for the CS 650 Unit and put it in and charged it for over 24 hours and guess what the CS650 is still beeping ?

please help laughing
