Suriya S asked:


i have 10 KVA Numeric UPS. Currently 20 SMF batteries has been connected. But is giving only 20 mins of backup time.
People say that backup time will get reduced very quickly in SMF batteries and advised to go for Tubular batteries.
Is it true? Which type of battery give more backup time atleast for next 3 to 4 years? is it SMF or UMF or Tubular?

Any help appreciated..

Dan asked:


Whenever I type anything on my calculator everything just turns a glitchy random black
I tried the reset trick (2nd “+” etc)
it does nothing
I tried changing the AAA batteries which also did nothing
I took out the backup battery though I did not change it but that still did nothing
Any suggestions?

Wei asked:


My smoke detectors (they’re wired into the house and I think it also has a backup battery) went off around 4am last night, at first it was a beep every minute or so. My dad went to check it out and when he tried to turn on the lights they didn’t work. A few minutes later the lights were back on and the smoke detector starting blaring but stop after a few minutes. I called the fire department but they really didn’t have an answer for me. So is the short power outage the reason the smoke detector went off?

nehla s asked:


I have a Dell Inspiron 1525 with a 9 cell battery. May I know how long the battery will be good for use. Mine is just over a year old and refuses to charge. Till four days back it gave me a backup of about 4 hours regularly, but now its stuck at 14% and not charging. Is it usual for batteries to last only so long. The warranty ran out about 2 weeks ago, so Dell wont replace the battery. It is not an OS issue as the problem is common when I am using Windows Vista and Debian.

My APC battery backup for this desktop keeps alarming and I don’t know why. It’s never done it this frequently, at least once every minute.

Before it’s only done it when there is a blink or sag in the power for a split second… Is the internal battery dying? What is going on?

I have one outlet and the treadmill says to use a single-source surge protector, which I have, but I can’t plug the tv into the socket unless I use some sort of power strip for the two.

Tonya asked:


I recently had a home inspection and was told that I can’t have my freezer hooked to a utility surge protector that ran through a hole in my drywall to the outer wall socket. They told me it was setup well, but that the power cord could cause an “electrical drywall fire”, I can’t find anything on the net about this. Any suggestions on this or thoughts. The house complex is the ones who drilled the hole, fire people says no????

Should you unplug the surge protector from the wall outlet during a storm?
