How many let you hot swap a battery? Surely that's a requirement, to be able to change an aging component, without having to power down the computer that it's supply. It is supposed to be an *uninterrupted* power supply. But out of the small number of consumer aimed UPSs that I've actually been able to see, they're virtually a sealed box. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
