apcupsd - system shut down on self test

[deloptes <deloptes@gmail.com>]

Hi,
I found today morning the server shutdown. When looking into the logs I
found that apcupsd performed self test. It said 

Jun  8 07:56:21 server apcupsd[2404]: UPS Self Test switch to battery.
Jun  8 07:56:23 server apcupsd[2404]: Battery power exhausted.
Jun  8 07:56:23 server apcupsd[2404]: Initiating system shutdown!

The battery was replaced 1 or 2y ago and also it shouldn't just shut down
when testing - this emberassing.

Did someone have this and how do handle it. I would like to receive an
e-mail, but not a shut down.

thanks
