Is this "tray" some sort of platform into which batteries are placed, wired, etc and then slid into the UPS? How high up on the batteries does this extend?
Anyway, yes, many of us have had batteries swell. Our (4) oldest RM-3000VA's each have two sets of 4 batteries, and the individual batteries are "unitized" by double-stick foam. If just one of those batteries swells just a wee bit, it's extremely difficult to get them out of the UPS. I have had some success with some small pry bars. One time, though, I had to shut down the unit, pull it out of the rack, then undo a whole bunch of little screws to take the top off the UPS. The following is far from "best practices", but we really have crappy air control in our server room (and a couple of us are begging for funding do deal with this!). Our racks lack sides, back, and doors. After the battery swell episode (which required the top being removed to get to the batteries), we leave a 1 U space above and below each UPS. Since doing this, we've had no more battery swelling events. -- richard Matthew B Ames <[email protected]> 04/05/2011 09:48 AM Please respond to "NT System Admin Issues" <[email protected]> To "NT System Admin Issues" <[email protected]> Press this button if the "To" is a fax number.

Check the voltage across the batteries, if it 0vdc (or pretty close) then you need not really worry about them shorting out, imho. -----Original Message----- From: John Aldrich [mailto:[email protected]] Sent: 05 April 2011 15:34 To: NT System Admin Issues Subject: APC battery tray Any tips for getting the batteries out of the "tray" in an APC UPS? Our rackmount APC takes 4 batteries and they appear to be *glued* into the tray. The guy at Batteries Plus was shocked that he couldn't get 'em out with a screwdriver by prying on them. A friend on another list suggested soaking the bottom of the tray in Goo Gone, but I'm afraid that might short out the batteries or something even worse... Is that likely to be safe and does anyone have any clue what APC used to secure the batteries into the tray? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ < http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin This email and any attachments to it may be confidential and are intended solely for the use of the individual to whom it is addressed.
