SMART UPS C1500, battery issue?

[BillP]

Hi, I have a question about the battery. I bought this unit and I got it yasterday but the battery is still not at 100%, I installed the software and looking at the "data log" battery is charge at 99.5 max, with a load of 22,7%. It's normal or I must run the calibration that at this moment it's blank (can't select it)? Self test seem ok. Sorry for my bad english I hope that my message it's readable.

Hi,

There is no need to run a calibration. If the UPS were to switch to battery it will sustain the load. A run time calibration should only be required when old batteries are replaced and the estimated run time is found to be significantly inaccurate after the replacement.
