I have a ST Presence sensor on my key-ring. About 6 weeks ago I changed the battery on it. But now 6 weeks on it’s reporting the battery is already at 25% this seems like a ridiculously fast discharge rate. The original battery also lasted about 8 weeks or so. Is something wrong?
sadly it is normal. Workaround has been to solder a large battery to it, or wire car power to it, which works well.
That’s a shame. Is there any better presence sensors that have longer lasting batteries? I guess now that I know the battery doesn’t last as long, I could buy a big pack of batteries
around 20th of July I replaced the battery with a duracell 2032 battery. here is a pic of the battery i bought
Will try Panasonic next and see how that goes
