Battery Backup Guide

Karl asked:


It says battery backup and has a spot for a 9 volt. Will it run on just battery with no electricity for very long?

. asked:


I am wanting to get a battery backup system for my house at night time. The batteries will be recharged by solar panels during the day.

mtm asked:


I thought that you need a physical contact between the charger and the battery so the electricity actually arrives inside the battery.
Now my new electrical toothbrush seems to work differently. It has a battery, the manual confirms. It also has a charger. But all I need to do is to put the toothbrush on the charger.

How does that work? Both parts are plastic covered.
Yes, a Sonicare product.

Andrew B asked:


I have never heard of anybody having their electronics damaged by a surge of electricity. Up until computers came in, nobody used them. Are computers really that sensitive to surges? Do you know anybody who has had a problem because they didn’t use the surge protector? Maybe its just a scam to sell them.

Your Highness asked:


I recently got a desktop, i’ve been using a laptop for the past few years.

I am already sick of the electricity flickering for like one second and shutting off my computer in the process while i’m in the middle of something.

Is there some sort of battery I can buy that’ll keep my computer from turning off during these 1 second power outages? If there is, what’s it called and where can I get one?

jessica9874 asked:


My husband and I just bought a new LCD television, with a “special” surge protector to cut down on “bad electricity” which is supposed to prolong the life of our tv. Any ways, the “special” surge protector has three prongs and our wall outlet only has two prongs. I have another surge protector that will work in a two prong outlet; so I plugged that one in and plugged my “special” surge protector into it. I only plan on plugging in about 5 things so I know I will not over load the outlet, but am I going to hurt my tv? Also does this defeat the purpose of the “special” surge protector?

chasnr asked:


In my basement I have three smoke detectors that are all hardwired to the electricity with battery backups. One of the detectors was chirping, so, I replaced the battery and put it back up. Well, it still chirps, but, it’s not the actul detector chirping, but from the ceiling hardwire. I have taken down the detector, and you can still here the chirp coming from the wired area where the detector was. I have even put the detector in another room to make sure. No other detector in the house chiprs nor carbon monoxide detector. It really is coming from the ceiling where the detector was. ?????

Lilly Belle asked:


My electricity was really bad, No one could figure out for months I had surge protection,battery backup,dedicated plug still had problem with OS and all drivers corrupted. After a long battle I got SDG&E to finally put a monitor on meter to check after 3 tests for 1 week each problem bad neutral and really bad subpanel. Now I have elec. fixed but PC wont recover. Did a recovery,reinstall tried eveything.It ’s going back to HP for bench repair but I have done this many times before & it is still corruptedwhen I get it back. Now that elec. is fixed can it be repaired by HP and ever really completely work fine? I have had to replace 14 PC’s,2 monitors,TV’s,VCR’s,DVD players, a new refrigerator,digital camera,2 cell phones,3 sets of speakers,1000’s of lightbulbs,my nerves and now 2 PC’s are going in for bench repair. Will they need replacing? or are they fixable? Dont tell me how stupid I am because I already know that .I just couldnt find anybody to believe me.

Joyful asked:


They’re coming to install soon. They offered us the battery back up for $40. I understand that if the electricity goes out the batter will cover from 5-8 hours of phone usage. We definately need it, cause the electric goes out alot.

But my question is this…what if the cable goes out? Sometimes it goes out all by itself. Other times, when the electric goes out, the cable goes with it. Will this battery backup work even if the cable goes out?

THANKS
I usually use a corded phone when the power goes out. And in my area, it happens alot. The cable doesn’t go out as often, but the last two times the power went out, the cable did too.
I tried explaining this question to the guy on the phone, but i dont think he quite understood.
