The business case for these things is very strong but to add longevity to the alarm I would go ahead and use 9v lithium batteries, the same type that I now use in smoke detectors.

I'd like to try to reduce the effects of zero maintenance during this period and implement an ongoing maintenance program for appliance longevity.

Nearly indestructibleIn terms of longevity there isn't a crazy difference but I prefer quartz.

I was googling around to see what others' experiences have been in terms of longevity and wear and tear.
