Is the government going to step in and do some thing now?
Yeppir, that would be the ticket. Make them redesign the battery so the terminals are on opposite ends. Then they would be incompatible with all your 9V stuff, but who cares, you'll be that much safer and think how much China would benefit from everybody having to buy new stuff that will work with the new battery.
But hey, it could happen, if one or two more incidents pop up like this, the safety police will be working overtime to save us all.
