Matrix 3000 (APC) has been showing battery communication lost for some time, talked to site tech and batteries are original over 10 years old. No runtime shown.
Replaced batteries correctly, put back online, self test at unit passes. Cannot do battery calibrations until charge on batteries is 100%. Currently at 98% for the last 24 hours, same as at install. Date was reset via network port for battery change. Battery charge % and voltage are same for last 24 hours. Checked the RJ9 cable from UPS to battery box, goes from batt.comm. on UPS to batt out on battery box. Red light for bad battery is lit on front at all times.
I cannot see and don't believe batteries are charging. Runtime shows zero since I can't do the calibration.
I am going to get the site tech to try a new RJ9 from a phone handset and see what happens.
Odd thing is it is...
