Simliar project:

Presence Sensor battery upgrade

Soooo, I’m supper annoyed with the presence sensor battery life… so this is what I’m doing. Since a CR2032 battery is 3v and ~240mah I figured I could take two AA batteries in series to get 3v and 1900mah capacity. HUGE difference! about 8x the capacity of a 2032 battery setup. I purchased a few battery cases with leads and project boxes. I’ve already made one for my motorcycle and popped it under the seat. So far, so good. I just want it to last more than 3 months! If the increase in compaticence is even a lowly 50% efficiency gain, which I am guessing it’s far more than that… the thing should last more than a year. If the efficiency is closer to 100% then I can probably expect 2 years out of this thing. I plan on making 2 more for my car and my wife’s car. What I do is set up …
