MISB Advice

Dear people,
I’d like advice on what’s the best way to maintain my MISBs. Some advise sealing it away, others say you should air it from time to time.
For toys like Leader Prime and Ultimate Bumblebee, am I right to say that it makes sense to remove the batteries since unused batteries leak over time? Also, for toys with electronics, are they like plasma TVs or other electronic gadgets that you really should turn them on from time to time to keep them in working order?
However wouldn’t that necessitate removing the toy from the packaging, cutting the ties, etc?
Any other relevant advice from those of you who have MISBs is much appreciated. Thanks in advance!
