How many AAA batteries is it possible to need? How many non-rechargeable ones is it possible to need?
For myself, I don’t like the waste and expense of batteries that can only be used once. I use rechargeable ones wherever possible. When I’m in the supermarket and see packets of 16 AAA batteries, my usual reaction is “What sort of wasteful person buys 16 of those all at once?”
But of course you can’t sensibly use rechargeable cells in everything. In particular, they’re not suitable for anything that uses a tiny amount of power and takes months to run them down.
Well, a few weeks ago everything of that kind in the house ran down at once, and I had the unexpected experience of needing to buy a packet of 16 of the things.
However, the strangeness of finding myself buying them was nothing to the strangeness of what I found on the box.
So there you go. I suppose it makes sense: microwaving the batteries seems likely to destroy both them and the microwave, but at least if you follow the instructions you’ll still have an intact, non-microwaved security tag afterwards. Maybe you can sell it on eBay or frame it.
I decided to go one better though, by not following the instructions at all. In fact I didn’t even microwave the batteries.
