Medicine may or may not be a "bitter" pill or spoonful to swallow.  That can always be fixed by adding "flavors" to make them more "chuggable" or "tasty".

Enjoying one should be encouraged or a pleasant experience.

Not so with batteries.  They should never be consumed.  That's an insignificant problem without a solution.

So every "remote control" or "small device" should be readily opened by children.  Making them otherwise only hinders adults or those "on a couch".

Backward or "sour 'coating' on a battery".
