Re: How often to change smoke detector batteries

said by TheMG:

Our smoke detectors which are wirelessly connected to our monitored alarm system have lithium batteries that are supposed to be good for 7 years.
...

Lithium batteries (9v) have a shelf-life of 7-10years. But in use, it maybe less than half. Which, is still 3-5x longer than regular 9v.
I may try that option.

Which brings me too, how does one dispose of the lithium battery? Do you trash them, or take to recycler or disposal at home depot/lowes/Rshack?
