I recently purchased a laptop to replace my destop and have a question about a power strip. I was wondering if I could plug a plain power strip (no surge protection) into the battery backup just to have an outlet closer to the laptop to be able to plug in more conveniently. I wouldn't be plugging anything else into it but just using it as an outlet closer to the laptop. I know you arent supposed to do this in some cases. What do you think?
Considering the low draw of power you intend for the UPS it will work well. I have two monitors on a strip plugged into UPS along with desktop, routers and modems, UPS handles all well, it's just shortens battery backup times. Have had to power down from outages several times without any probs.

Yes it will work just fine make sure that the outlets you are plugging into the 3 are surge protected. Thanks for using FixYa! Most battery backups and backup modules are surge protected on-board. John
Yes, it can. I have replaced more than a couple of poorly made Chinese gel-cells after fairly brief service.
Also, you can extend your UPS's service time before the battery is depleted by turning off the monitor and settings the Power Management settings to power-down hard drives after 10-20 minutes.
In my experience, the ratings on UPS systems is wildly optimistic regarding their backup capabilities.
Also; the protection against lines surges caused by even distant lightning strikes is fairly minimal.
If this is in your home, you might consider installing a 'whole house' surge arrester.
Depending on the maker, they offer up to $10,000 in damage insurance to cover any losses not prevented by their devices.
The plug-in strips with 'surge protection' have a 50 cent component in them to clamp spikes to ~200VAC and these even get tired with repeated surges and eventually become totally ineffective.
If the battery checks out OK, the circuitry responsible for switching from AC line to backup mode may have already been damaged during the storm.
Switching to the 'surge protector' mode really only provides mildly conditioned AC line and involves no active electronics.
clear and simple. the batteries are bad.
they last about 3-5 years usually.
"batteries plus" in your area will usually replace them and dispose of the old batteries.
In the past I have replaced the batteries myself and taken the old ones to a battery surplus house and gotten a few dollars for the old ones (battery core).
