You can also change the constant with commands through Hyperterminal, but if you make a mistake or send the wrong command you could brick the UPS.

APC UPS - Replaced Battery, low runtime
Thanks to tomearnshaw from: Wow, that's so odd that I was thinking I finally need to do the manual calibration this week since I finally have some spare time. Battery constants are different depending on the unit's model, if you google around a bit you can usually find them, or in a pinch just bug APC tech support until they tell you what the default is.

Many thanks in advance. I've run a self test and a calibration on it but it didn't make any difference. Battery constant is out of range in the firmware. I have a SUA I bought with bad batteries, pulled the battery connector out of the back and connected to 2 wal-mart trolling motor batteries for ish Ah.

Now that I've plugged my gear into it, no where near close to the max load btw, the battery light won't stop blinking. The management software calculates the runtime of the UPS with these constants. Figure out the nominal voltage it's expecting probably 48Vand then connect a few batteries in series to see if there's one faulty one in there.
I haven't tried this but it sounds interesting: Mar 9, 3. Click here to start a new topic.
This is not a forum for general discussion of the article's subject. Manual calibration in the web interface? I guess I have until next weekend to decide Views Read Edit New section View history.
