Remaining battery time when power is interrupted

This was originally posted on APC forums on 3/20/2014


Hello.


Last week, I purchased APC Back-UPS ES550 -UPS - AC 120 V - 330 Watt - 550 VA - USB output connectors http://www.canadacomputers.com/product_info.php?cPath=32_438&item_id=019662


There was a brief power outage yesterday evening, and my UPS worked perfectly.


However, when I looked at the computer screen right after the power outage, the battery remaining percentage was 78%. Before the power outage, the battery was full (100%). Is this normal?


3 things are connected to my UPS - late 2012 iMac (base model), Creative Inspire 4.1 4400 (speakers) and a lamp


Thanks in advance.

Hello,

It really does depend on a few different factors and until the UPS battery is used a few times, you may see this type of thing. How much load is on the UPS and how long it operates on battery can factor in to how it behaves. You can keep an eye on it but it didn't jump out to me as a problem.

You could also do some further testing with a different load, like a lamp (but still at least leave your iMac connected via USB to monitor capacity) and see if you pull the plug on the UPS how it reacts with a different load.

How long was your UPS on battery operation? It sounds normal if you had a several minute power outage. Can I ask what you were expecting and why? Then I might be able to clear up what occurred.
