Am I doing something wrong?

I bought this back up a few months ago and I lost the manual. My problem is the battery, its not working. I am having a hard time getting the battery out because one of the connecters is not coming off the batery and i am afraid if I keep pulling at it, i might break it. Can anyone tell me how i can get one? Thanks Lisa

Re: am I doing something wrong?

Http:// Above is the link to your manual. If unit has not been powered up in several months then chances are the battery is dead and needs to be replaced. The terminals on the battery are slip on and off. Don't worry about breaking anything, it can be recrimped if needed. Use a pair of plyers and take the connector off of the battery and replace it with a new one. Make sure you observe the battery polarity when replacing. + for red connector and - for black connector.

The batteries in a FERRUPS typically last 3-6 years depending on how many power outages you have, how much heat there is, etc. So, 3 months doesn't sound right. Hopefully, you are buying batteries from a reputable source. Eaton bought Powerware about 6 years ago and retained their service network which has lots of techs trained on the FERRUPS. I suggest you contact them:

To High tempreture

COMPLETELY unplug your computer before attempting this:

You need to remove the computer casing, usually there are screws in the rear of the unit, or some units have the sides that slide off.... Get a can of Air, and some cue-tips, and clean out your fan for both the power supply, your processor, and any other fan inside of the unit... Get rid of all that dust. This should be done maybe once every few months at least. Yes, get rid of ALL the dust... be sure to be careful while doing this, do not want u to damage the computer>.<

There's more if that doesnt work, but I'm not sure how technically sound you are, so I don't want to throw too much at you all at once :-) Lemme kno if that works.
