Low DC Voltages of APC UPS SUA2200i

This was originally posted on APC forums on 2/8/2011

I have a SUA2200i. I have observed a problem in this unit. Backup time of this UPS has decreased. I have changed new batteries of 17 Ah but backup is still short. When I check the batteries voltages after charging 8 Hours thats are only 51.0 Volts. While in Hyper Terminal Window Battery Voltage are 55.

Tell Me how can I increase battery Voltages
