SUMMARY

1) I own a (Dell) laptop, which has a built-in battery. I have charge start/end thresholds configured to maintain the battery's health. This is reported correctly by the battery applet (neat!).
2) I also own an APC UPS to which my equipment is plugged in when I sit at my desk. I have the UPS connected to the laptop with a USB cable. Linux detects it as a USB HID device, and then (I believe) UPower and Powerdevil pick it up and correctly report its battery levels (also neat). To my knowledge the UPS does not support charge start/end thresholds. The UPS is not listed under /sys/class/power_supply, but `upower --dump` lists it, and does not mention any thresholds.

The bug lies in the fact that the message "Battery is configured to charge up to approximately 85%" is displayed beneath both the laptop battery (correct) and the UPS battery (wrong). The message is not displayed under any other devices like mice, headphones etc. (also correct).
