Question Garmin Minimum temp rating

Does anyone know if Garmin Edge have a minimum temp rating mine turned itself off and wont turn back on?
.
thanks if you know the answer to this dilemma

they like to turn themselves off, it's one of their favorite things to do. My favorite trick is when you try to start them up and everything looks normal until they just turn off again.

It might just be a sign of a weak battery. Lithium batteries don't have very good capacity at cold temperatures. Put it on a charger for a while and then press all the buttons at once. Or whatever the reset sequence is for your particular model. On my edge 800, you push the two buttons on the front and then the power button.

What temperature did it get down to on your ride? I generally keep mine on an external battery, but I have had no problems on long rides in the mid-20F temperature range. Going to test this whole theory on a ride on Saturday, temps at the start look to be in the mid-teens.

According to the manual for my Edge Explore the operating range is -4 to 140 F (-20 TO 60 C) and can be charged from 32 to 113 F (0 to 45 C) I don't know if they are all the same but would think they should be close.

I think this is universal for edge products. BUT when its cold the battery drains super fast.

huh, so I shouldn't be charging mine on the bike. I think I will continue to ignore that specification.

For reasons that I do not understand, battery manufacturers often recommend against charging Li Ion batteries in sub freezing temperatures. Do an internet search and you find that it is a hotly debated topic amongst battery experts.

I think some liquid crystal displays don't work as well in cold weather, but a GPS that is intended to be used outdoors should have a display that has a wide temperature rating.

well, the garmins are lipoly, I'm pretty sure. But I imagine the charging problem is similar.

The "resistance" heating from charging below freezing might be sufficient to keep the battery warm enough for the unit to function. Since it ain't blowed up yet, I'd keep doing it.

Brought I home and put it on the charger. It did not turn on all day.
I just tried to do a reset and the second time it turned on and asked me if I wanted to save my activity.

So it might be back in business again. I think. 🤞

Yea...IRL Garmin LCDs get laggy and the display non-functional a good bit above zero. I want to say 10F or so.

The computer still records data...but liquid crystal displays have problems doing their thing.

I assumed it would, it usually takes some patience to get them restarted after they spontaneously turn off. But I always feel some trepidation until I see the logo displayed.

14F is really cold. I have ridden in as low as -24F, but mid-teens is too cold for me nowadays. Which is why I'm hoping to ride 200km starting at 15F tomorrow. What is wrong with me?

Absolutely nothing - that sounds awesome. I wish I lived closer to the Twin Cities, as there are folks that do that kind of thing pretty regularly, and I'm too lazy to ride solo distances in the cold.

One of those folks in the Twin Cities had a picture of a Garmin 1030 running at -21F. It sounds like it was fine other than the very rapid battery drain.

my ride was cancelled because it snowed today. That's a bit annoying. It's going to be really slippery tomorrow until at least the afternoon. Sunday should be much better and then Monday, Tuesday and Wednesday we are going to have a heat wave.

yeah i guess when really cold like that i should put it in my pocket vs letting it hang out on the front of my bike with the wind and cold temps. Plus I will make sure to charge the battery up.

The "minimum" temperature is going to be for the display and for the batteries. Everything else is probably more worried about the "maximum" temperature.

The display probably won't get hurt at all by the cold. It's just going to get really slow and laggy. It may stop working but the computer will probably think it's still working. The main problem is going to be the batteries. Li-ion batteries do pretty well in the cold and hold their capacity better than other chemistries but you don't want to freeze them solid (freeze is a bad word, no water in there - but deep cold eventually causes the voltage to drop too low). If you do that, they can just die. Generally, unless very deep cold, Li-ion batteries won't freeze if they are being used. Prudence would dictate keeping the battery from freezing. IIRC, the freezing can cause a permanent capacity loss but the real danger is if you try and charge them when very cold with a charger that isn't smart enough to deal with it.

Really cold is REALLY COLD for most people. I've used my Garmin Edge 1000 on a front mount on my fatbike down to near 0F and ti was fine.
