Battery Backup Guide

tomma0264 asked:


Even though I removed the battery from my PSP, a little while later I put it back in, turned it on and the time was correct - there was no source of power. Does it have like backup power from the battery or something?
Another thing I noticed is when I unplug the computer, even for weeks, it keeps track of the time, internet or no internet (i think)

Ok, so me and my friend like to study at a Denny’s where they got free wi fi, which is like AWESOME. But…. there is nowhere to plug in my laptop, so once battery runs out we gotta go.

So what kinds of things are there that can power my laptop once my battery runs out? Some kinda backup batteries? Power supplies? Where do i find them?

I have gotten three of these back-up batteries to protect my computers and I got them used.So I did not get any set-up software and instruction booklets.I am not even sure if the batteries are any good.I tried looking at the website and I had no such luck.

I work for a hospital and we were given “hand me down” iPAQ pocket PC’s from another department. Some of the units are showing no power in the back up battery. Where in the unit IS this backup battery and how hard would it be to change out?

Fuji_mans asked:


Ok, we all know that UPS are expensive as it is. And every 2-3 years you have to change the battery.

I have an APC BE325 which is a 325VA. The battery is a 12V 3Ah. There is no link to a computer so no software to test the battery or limit the use of different battery.

So I wanted to know is that could I put a car or marine battery in it to increase the backup power since they are both 12V. And is there anything to be concern about before doing that?
Should I worry about overheating if I use a deep cycle battery? Also would there be a problem with a much larger ah battery?

Gardener_SA asked:


The battery is a 12V and the garage motor is 220V. Can I simply connect the battery to a 220Vinverter to convert dc to ac?

Hi, can someone provide a way to calculation how long a 5watt CF bulb would last on a 3000mAh backup battery? Thanks!

don’t steal my idea, this is considered “in writing” and I said it first.

I think it would be a very useful addition to homes since most of our electronics require DC power. Just about anything you plug into the wall that has a big black box on the cord is taking the 120V AC voltage from the electric companies and turning it into a much lower 6V to 24V DC power. This could be avoided by having a self contained power source in the basement with a gas powered generator.
Think about it. with our homes battery powered, a ‘power-out’ could shut down your neighborhood and you still have your DC powered electronics. your laptops, cable modems, routers, etc will still be working.
My home uses a cable modem that also takes care of my phone line. in a blackout, I loose my telephone. But not if it has a battery backup. They already make battery backups but why not have it central to the house. and with gasolene recharging it you have that power in case of emergencies.

Got a battery backup that only has connections for the 20amp type sockets. Is there a converter that will allow me to use this for my regular plugs?
