All batteries will get hot when short circuited, not just re-chargable ones. You could find some power supplies that have circuit breakers or just live with the possibility of having kids ruin batteries from time to time. I doubt that the kids will hurt themselves - they feel the battery and drop it long before any injury occurs.

>I have been told that rechargeable batteries are not suitable for "build a circuit" activities with kids because they can get hot when short circuited and/or dump their entire charge at once.

>But I'd love to get away from using disposable batteries in our school programming, where we have kids building "dexterity testers" (in the style of the game Operation).
