Consider reversing a flashlight battery, the easiest one to get to and turn around, to cut the electrical circuit during storage.
Bare in mind that when you try to use the torch, it won't work. You'll have to remember what you did, which may be difficult if several years have gone by ....
Recall is not difficult if last-battery-reversal is your invariable habit - and the non-working "torch" should be a reminder. Switching the last battery around should not normally be a big challenge, though I concede if an emergency has disabled one hand-arm you now have two problems.
I reverse battery my secondary line of flashlights, the ones that are placed around the house for urgent need. I do a single wrap of blue painters tape around the lens or tube & write on it that the batterys have been reversed for power savings. Especially good when little tykes like to play with flashlights.
Whole family recognizes the meaning and when needed, rips off tape and batterys around for use.
