I was talking to a tech support person about one of my weather stations that was not working. I told them that I had put lithium batteries in the outdoor sensors for winter. The tech person said, in so many words, that using lithium AA batteries in the weather sensors was not recommended unless it gets very cold in your area.
Like sub zero cold more than a few times a winter.
Of course I can't remember the exact reason, but the voltage levels of AA lithium batteries can affect the electronics in a not good way.
So the not working weather station is on its way back to the company that makes them. And I've taken the lithium batteries out of my outdoor weather sensors.
BTW, this indoor outdoor temp display works pretty well. I have yet to find the best one ever, but I have three of them and they work.
From what I can tell from various forums, lithium AA batteries work best in flashlights and other high power drawing devices. Weather station sensors are the opposite, just sending a bit of data ever minute.
Could you fill in the blanks on how lithium batteries affect electronics?
