Had need to replace the button battery in the Car key ring. Accessing the battery, despite a 17year old design requires tools and skills that might defy many adults. And an unusual profile star or Phillips head jewellers screw driver, in two sizes.
The new battery package was definitely adult resistant requiring two goes with the scissors to outwit the double sealed encapsulation. Must be in anticipation of the new standard.
That just leaves safe disposal of the used cells to manage. Perhaps the battery suppliers can offer a small child resistant jar with locking screw top or one way slot in the lid. Or a sealable pocket in the packaging especially for the used one. One way adhesive to secure the battery to the package and permanently seal the opening.
The risk remains of all the legacy toys and devices that hold these button cells, and pop open easily. Perhaps the improved security of the packaging will help increase awareness and everyday consumers will think about replacing the devices with insecure battery compartments. Hope I’ve been double guessed and such advice might make it onto the battery packaging.
