There is a Kiddie fire extinguisher recall which involves 134 models manufactured between Jan 1 1973 and August 15 2017. Check the kidde website if yours is affected. http://www.kidde.com They will send you a replacement extinguisher free of charge.
Interesting that you posted this on KIDDE - Fire Extinguishers. Was told two weeks by my mother and the details. I was surprised that the time period in question is over four decades long.
To be noted....that this includes KIDDE - Fire Extinguishers that many private vessel owners (along with For-Hire) may have upon their vessels.... CHECK THE LIST on the site I posted below since this is this on CPSC.GOV (This is the Government - Consumer Products Safety website):
Units: About 37.8 million (in addition, 2.7 million in Canada)
