Brought up a question bothering me: How can one tell if FE is still OK?
Mine is a very old Kidde, big red puppy; A.B.C. Indicator is still in the green, albeit leaning toward the left (recharge).
Has never been used(thank goodness!)
However, I don't want to find out the hard way that it is over the hill.
Can I squeeze the lever a little, to see if it works? Don't hit me; I'm just ignorant!
The new ones that size range from $40+ on up. I'm not trying to nickel & dime my home's safety; just want to know if there's a way to test this. If the test shows it's still good, fine. If it shows no good, at least I know what to do, $$ notwithstanding.
Any help appreciated.
