I don't think putting volts on a capacitor stops it drying out! I also have a unit in storage.
Storage of spares is a tricky subject.
These days batteries in equipment are the biggest problem for storage, especially if they're rechargeable. Lithium Ion batteries are permanently damaged if you let them go dead flat in storage, you should aim to keep them around 50% charged (fully charged is bad for them too). Some other types of rechargeable batteries eventually eat through their casing and then start eating through the PCB with acidic or alkali chemicals that come out of them. Newer gear isn't so bad for this, backup batteries in consumer goods appear to be falling by the wayside thankfully in favour of Flash or EEPROM and clocks that simply lose their time on power loss and then get it over the air or Internet when power comes back. Supercaps for backup also seem to be less of a problem.
After that it's electrolytic capacitors drying out, but that takes quite a lot of years.
Corrosion can also be an issue.
Storage locations should be cool and dry if possible. My HDR Fox T2 stash is in the loft, not the best place but better than the garage which is damp due to being a seperate building.
