This will be interesting. I have not added a battery to my 3801. Have the same issue annoying but in general not enough to get me to do something.
But believe it may be as simple as taking a cr3026 lithium as an example and holder. Slap it on the back and change the battery every so often. Doing something with recharge-ables and super caps adds a lot of complexity. Using the disposable battery should make this a ground and battery connection. Do not believe a diode is required. But this approach only works if the almanac memory and such draws very very low current. Might guess in the 1-10 ua. If its a pig you could always use 2 AA alkalines.
