Ask Sterling: How Long the Honeywell 5811 Battery Lasts

This week, Josh from Connecticut had a pretty standard question a lot of us have before purchasing any wireless products: how long will the battery last?

Specifically, he wanted to know how long the battery in the Honeywell 5811 last. The Honeywell 5811 is a wafer thin door and window sensor that isn't as clunky as its counterpart, the 5816. It's button battery may be small, but it is very very effective.

While the answer to this question is obviously based on usage, I tried my best to answer Josh with a general estimate based on Honeywell specifications and average lifespans on Honeywell CR2032 3V lithium batteries as well as our personal experience with these sensors.
