EnerWave ZWN-BDS Battery Life

Hey all,

Thought I would share a bit of information I got today from Enerwave regarding their door/window contact sensor and battery life

I contacted them since the battery is still showing 100% after 3 months of use on my front door

Here is their response, “According to our the response I got from China. Apparently, the ZWN-BDS uses extremely tiny bit of power each time it was used, plus the lithium battery provided is supposed to last more than 5 years.”

That’s pretty fantastic if it holds true
Have fun

Well… what I found in this case is my device is defective, it reports 100% with any battery I put in, regardless of the actual level.

Service is going to replace it for me

I can’t speak to how battery friendly the device is just yet
