Gee Ken, I hope you don't park your car/s in your garage attached to or forming a part of your house......... I'm not sure where you are located. In most places in the US (and I'm certain of Maine and NH), building code requires fire-resistant construction around an attached garage. --ron |

And of course, like Ken said, who wants a lead acid battery in the house? John Wrong John. How do you think UPS systems work? How exactly do *you* think that it works? If you think that you can run a computer on 12 volts DC current, and if you think that you can charge UPS batteries with a 12 volt car battery then you don't know how things work. Unless specially built, the input requirements for almost all UPS systems is standard household current. John |

The UPS uses household voltage and it has a charger in it that keeps the battery in the UPS charged up. When you have a power failure, the UPS uses the battery inside to supply power to the computer (of coures it must be changed to 115-120v).. The bigger the battery, the longer the power will last during a power failure. This is what must be replaced in an UPS every 3-6 yrs. So, I was just thinking that if the battery inside is 12v then you could probably use a sealed marine battery or similar and not only would it be cheaper, it would supply power much longer during a power failure. Of course you would have to do a little soldering, etc. |

Think John, think. What is the purpose of the UPS? Supposing you lost your
AC power, where would you get the AC power for the UPS? "John John (MVP)" wrote in message ...

Why do you need it?

What are the consequences of loosing power to a computer (XP Home, SP3) when it is operating normally and when in the Standby state? from personal experience the $150 or so investment in a ups is much better than a fried pc / hd / whathaveyou. i recommend a ups for all sensitive equipment, and surge protectors on all other electronic equipment. |

Oh for crying out loud! If you insist on running your computer off deep
cycle batteries then design your power supply solution around that, don't try to mickey mouse a factory UPS to use batteries it wasn't designed to use! John Unknown wrote: Think John, think.

John I think it's feasible and I was just asking. Saving around $100 for a longer lasting UPS (how long it supplies power after the main power is off) is still quite a bit of money for me. Since I recieved no helpful replies, I consider it closed. Thanks |

John To make the UPS supply power last longer during a black-out and because of the software supplied with the UPS. But never mind, I think we are talking about two different things. Bye PS: It's the size (capacity) of the battery in the UPS that LIMITS the time it can supply power to the PC during a power failure. |

John I think it's feasible and I was just asking. The battery charger inside a $100 UPS is designed to charge the 5 to 10-amp hour battery that it is designed to use, do you seriously think that it will be sufficient to properly charge a 100-amp hour or more deep cycle battery? Do you think that you can properly charge a 100-amp hour deep cycle battery with a 1 or 2 amp trickle charge? John |

Bye PS: It's the size (capacity) of the battery in the UPS that LIMITS the time it can supply power to the PC during a power failure. Yes, we all know that the size of the battery will determine how long the UPS can supply power. What you don't understand is that almost everything in a cheap $100 UPS is woefully inadequate to properly charge and maintain a 100+ amp hour deep cycle battery. John |
