My Xbox doesn't keep time and date when it is unplugged for couple of days. It is annoying for me. Is there a possibility to mount an additional battery (like in PC) to keep time and date?

Yes, but it's far easier to set up your dash to get the time from an NTP server on the Internet every time it boots.

But when I have not access to the Internet? Where should I place the battery? And what about voltage?

depends on motherboard revizion. and the batteries arent a great idea. you really need to wire them in so they dont get re charged, so you have to keep replacing them..

but basically you replace the cap with a battery coin slot. There should be a tutorial some where around here.

I have motherboard 1.1 and 1.4
I searched, but I didn't find any tutorials.

Btw, which server (IP and port) do you suggest to use in UnleashX for time-updating?

139.143.5.30

Which capacitors are for keeping time? I have different 1.6 mobo, which doesn't keep time at all.
