No I took the battery out of an old UPS that quit.
I cut the cigarette plug off of the cord for the DC adapter
and hooked it to the old battery.
You could also get a small lawn tractor battery and do the same thing.
I can charge it with my car battery charger in the 2 amp mode for a short while.
HMM....Better not fool with it myself.
With my luck I would electrocute myself or set my tv on fire.
I would be better off having a UPS that I can just plug the little TV adapter into.
Wanda: Power out...UPS kicks in and supplies PC with power. Some as little as 5 minutes, some as long as 40 minutes...depends on equipment and power of battery. The battery units discharge and recharge repeatedly but eventually they get weak/die. My last one lasted 3 years and finally had to be replaced. They often go on sale at office supply stores.
Example search for them h**p://www.officedepot.com/textSearch.do?uniqueSearchFlag=true&Ntt=upsTo buy one, you need to know your equipment. Most people only plug in Monitor and CPU. But you may need to plug in an external drive or something else too. Usually people put printers/scanners into the SURGE protection only plugs on the UPS so they have some protection from surges and spikes but no backup battery time.
Stronger/higher rating gives you EITHER:
longer time to close safely OR supports power hungary equipment OR support more less powerful pieces.
I have weak equipment so I get a strong UPS to give me more TIME.
With Windows operation system, having a few minutes to safely shutdown your computer
when the power goes out is important.
Even better a short interruption won't cause a data loss.
Lots of small Windows corruptions are caused by sudden hard shut downs that occur at inopportune moments!
We have the UPS units on every machine at the office and I am THANKFUL for it!!!
I have a strong UPS because we have tons of tiny 1-4 second brown-outs in my area. While working in the pc on bright sunny days or clear evenings at least twice per week, my power gets interrupted enough to shut down tvs, dvds, etc but the UPS backup battery allows me to keep working. Having a battery unit on my computer is a MUST.
