battery in computer

[dingusbird]

is there any danger of damaging the parts in a computer if I have a battery connected to a drive that is no way connected to my power supply??

I don't think so because in older computers there is a battery for a clock inside. I don't think that putting a battery would hurt a computer if its not connected to a power supply.

Maiman1 is right, i think he means the BIOS battery which all computers have, although this is linked to the PSU through the motherboard indirectly, also laptops run on batterys most of the time. Iv never heard of anyone running a drive of a battery though. ~If your concerened about keeping a household battery in a PC case i think it would be OK, although read the label first to check the safe operating temperature and dont go selotaping it to a big source of heat. (HardDrives kick out a lot of heat 50 degrees or so, so watch for that)

Can i ask why you want to run a drive of a battery? (if that is what you intend to do)

All computers still have batteries for their BIOS chip, if you take that batterie it will reset your bios and clock, also can screw up ur motherboard if you dont watch what ur doing.

Im not sure if a battery has some sort of magnet in it or not but if it does then you can have a large chance in screwing up your hard drive and a possibility of screwing up ur monitor as well.

In all honesty, i doubt that's something you need to worry about...

Put a magnet up to your hard drive and see what happens... more than likely it will erase the memory on each of those disks. Also leave a magnet next to your lcd screen for an hour or so and you notice on the corner of the screen it will start fading your colors or start changing slowly greenish/blueish bt after you turn your monitor off and on it goes back to normal.

Truly don't try this I was just giving an example of what happens.

Okay, now try doing the same thing with a battery. Any magnetic power a battery has would be far too weak to do any damage to a hard drive, unless you are using something truly enormous.

Even with a huge battery, the magnetic field is too weak to even cause interferance. I used to install a computer in the same room as a LARGE battery backup unit for card access and video cameras and never had any issues.
