Help with a used APC BE750G

This was originally posted on APC forums on 9/30/2012


Hi,

I am hoping someone can give me some advice. I picked up a used APC BD750G UPS. I pluged it in and charge the battery for 24 hours. Then I pulled the plug from the outlet and mesured the output at the Master Outlet. It read 87VAC. Should this not measure somewhere close to 120VAC? Suspecting the battery to be aged and weak, I pulled the battery and measure its output. It measured 13.1VDC, which I believe is a normal reading.

Any thoughts? Where do I go from here?

Thanks,

Dennis

yes, this is a common question. take a look here-> http://www.apc.com/site/support/index.cfm/faq/ and search for FA157483

essentially, this is expected if not using a true RMS voltmeter which is required to properly read the type of sine wave this unit provides.
