I have an old UPS Model # BK200C that was never used after purchase 10 years ago. When I plug the power cord into an outlet then flip the power switch the I/O switch light is lit. Does that mean the unit and battery is still operable? Can the unit still operate as a decent surge suppressor if I remove the battery without replacing?

Your batteries would have been weak from 5 years of use. The Lightening could of blew out one of your batteries. The UPS did it's job but at a price. I would replace the batteries first then see how it works
Go into the control panel and find the device manager. Then locate the UPS unit and right click and update driver. Then pick roll-back driver. This should install the prevous driver that was working properly. Then when you do windows update make sure to set it to hide that update so you don't re-install it again.
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.
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
Try turning the unit off for a little while, unplug it from the source even. afer about 5 minutes plug it back in and try it again. You may have a bad battery, how old is the unit. UPS batteries should be changed out every 3 year's, max every 5 year's if you want good reliability. At 5 years you are taking a chance.
