I have this Panasonic portable VCR and tuner/timer dock from 1984. In the dock I have unfortunately hit a snag with these three capacitors as I don't know what they are as there way bigger then anything I have seen while only being 3.3f at 2.3volts. I have included a picture of the three caps in question. I need to replace them as they are leaking.

I know they're used for memory backup. Other brands used those round disc style snap in batteries.

Yes 3.3 farad capacitor and they're known to backup CMOS memory for months.

Okay thanks. I noticed I made the mistake of calling it 3.3uf instead of 3.3F. I did go back and correct my mistake. Well I ordered some new super caps and along with some other values I needed. In the past on the round disk caps I just removed them instead of replacing them as let's face it I'm not going to be using the timer to record anything as let's face it there's nothing worth watching on TV anymore in my opinion.
