Leaking clock capacitor

[Albatross]

The aerogel clock capacitor has started to leak on one of my xboxes. I know a lot of folk simply remove them but I would like to replace it if I can.
I'm not to sure what I can & can't get away with as I know the original capacitor is rated at 1.0F, 2.5V, could I replace it with a capacitor rated at 2.7v like one of these or has it got got to be rated at 2.5v ?

It can be rated 2,5V or higher.

Okay - thankyou, I'm going to give the 2.7V 10F Super Cap a go.

People over forums don't recommend replacing this clock-cap. It could leak again soon, and keeps date for a short time. Better (and cheaper) solution is small NiMh 2,4V battery:

Yes I've read discussion's on replacing the capacitor with a battery but not actually found any posts by anyone thats actually done the swap.

Modern day good quality double layer electrolitic caps dont suffer the same problems of the previous generation of caps and leakage is almost a thing of the past.

I have a 47 farad cap and it keeps the time for a week or two on my xbox.

they expected the xbox to out last the shelf life of a common cr2025 battery so they installed areogel caps also because of rohs and reach regulation in the uk as ni-cd batterys have harmfull heavy metal cadmium.

I noticed a an old leak on one of my mobo's and that the cap was a 3300uf 10v, is this the clock cap ?

[MrMajst3r]

No. Stock clock-cap is 1F 2,5V. It's placed in left bottom corner.

I've soldered there a small NiMh battery, as posted before. It works, but I can't say how long it keeps date, because I often use this console.
