Back UPS Model # BK200C salvageable?

10.3v during test, BAD THIS.
night lite is 1/4watt LED , useless (mostly) as a test use 100watt desk lamp (old skool(sic) not led)
the kind of lamp that burned grandma's hand/ see?

that battery is no good
or was never charged up up but 13.7v proves it was.(kinda)
a battery has many failure mode.
one is dead (0v)
or at 10vdc all the time cell shorted or dead open cell 1 of 6)
or acts like 6 , hearing aid batteries, in series. and 100% end of life and useless now and common after 3 year old or discharged deep 300 times, in your mind imagine old cells , shrinking !
not dead, not good but shrinking and amp/hour is not 7 but 10 times less, called EOL, end of life.
dead
weak
shorted
intermittent
and all are EOL (bat 101 end)


always try new batteries

It is probably a bad battery. They usually don't last much longer than 2-3 years. You could try replacing the battery, but I would suggest just replacing the whole UPS with a new model.

Take the tv back cover apart,check the tv power supply board,that the board where the power a/c cord plug into it.Check all over the power supply board,for dying parts call capacitors.The dying capacitors are alway bulging or puffing ups on it tops.U have all the tools and understanding basic electronic also can do basic soldering?Yes.Repalces all those dying capacitors,with new capacitors with same Micro Ferid but the voltages higher like 5 or 10 voltges for better heat resistance.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

These models were discontinued several years ago and it is possible that the batteries are dead from age.
If it is this model type that you like, you may want to purchase a corded model instead. Corded model simply plug into the wall and run from the cord. You will find this type at shaveroutlet.com. See link below

No power could be a broken wire in the power cord, usually near the plug end. It could also be the switch, or the motor brushes. More rare is a broken wire in the motor or the saw case. Hope this helps!

APC 500VA ups meant for 1 Desktop and one montiro it will have battery backup for 10 to 15 minutes for the above.

Normally, You should make the raw power connected to UPS should be always ON.

The power cables of CPU and Monitor is connected with UPS. When not in use, please press the Button available on the UPS.

The UPS Life is normally 2 to 3 Years only. Now you are getting the sound and Red Light will always blink and not allow to use the system.

Better replace the 12 Vols battery to get some more life for the UPS.

And check for any loose connection of the power cables connected with Raw Power and UPS System.

Yes, but the battery may not be any good, though, and trying to charge it may damage the charger. A new battery is about $20. The surge suppressor will still work without the battery as long as it is connected to a properly grounded 3-wire circuit. If you decide to take a chance and charge the old battery, take precautions like keeping a watch on it should it explode or catch fire. Not trying to scare you, just looking at worst case scenario.

Any UPS monitors the incoming AC level to determine if it is needed or not.  I think the APC unit doesn't know any more when it is needed; it's sick.

If the battery outlets do not work, typically the Dynex TE685AVR UPS (battery backup) just needs a new battery. These batteries usually last 3-5 years.

The model of the battery is a WKA12-7.5F2 and can be purchased at: http://www.replacementupsbattery.com/Product_pages/wka12-75f2.html.

I have the same problem.
It is most likely the battery.
I tested my battery on a Shumacher trickle charger, and the battery wouldn't hold a charge.
This is a common problem with UPS systems that use sealed lead acid batteries.
The longest life that you can expect with these types of batteries is 5 years MAX.
The battery can be replaced with a Radio Shack 12V/7200mAh Lead-Acid Battery
Model: CNB-GP1270F2 | Catalog #: 23-9030
Here is the link for the UPS users manual.

To replace battery, (unplug AC cord), turn the UPS upside down on floor or workbench.
Remove the 6 deeply recessed phillips screws, then pull the bottom off.
Remove the wire leads from the old battery (pull on the connectors, not the wires). Install new battery (red wire to red or + sign) and replace the bottom and screws. Careful, tighten the screws finger tight (plastic strips easily).
Plug in UPS and you should be good to go.
Hope this helps
