The cap is 2.5v with a 1 Farad capacitance.
FYI, that cap is only responsible for keeping the time set in the event that unplug your xbox from the wall outlet, so you don't really need to replace it, unless you have a super old softmod, or no M$dash installed. Simply removing it when it begins to leak it is sufficient.
Thanks a lot! So, yes, it is leaking, and already not working, because the Xbox loses the time as soon as I unplug it. Well, you have saved me from some work, I'll just remove it. Thanks again!
