How well does this charger work in extreme cold weather?

Good question! The coldest I have ever used it was maybe, 29°C. I realized it had been awhile since charging, so I plugged it in and it took about 1.5 hours for a complete charge. This is a nice little unit for the battery which Autozone and AAA test and want to replace, and then you re-charge it and it's fine for another 3 years. It is NOT a service station-rated unit. It will re-charge a dead (no spark) battery with a deep cycle in about 3-4 hours.

It doesn't start charging if the temperature is below a certail degree for safety measure. But you can warm the charger in a warm place then take it out and quickly hook it up to batery and plug it in. That way it starts charging even if it's very cold. It's a great charger over all.

Hey there, I left mine plugged in this winter and it completely drained it and it wouldn't hold a charge. The note on the charger clearly says not to keep it plugged in at cold temperatures. So totally my fault. I went to Batteries Express and had it replaced(well there are actually two inside of it), just shy of 120 bucks, but cheaper than buying a whole new unit.

So far I haven't had an issue with the cold. I like in northern North Dakota and it's worked great so far. Battery life is a bit shorter but I get the rechargeable batteries

Well, most of the time high temperatures means way up in the 100s degree, I don't think anybody uses that battery charger in those hot temperatures, and the only reason they say that is because heat decreases the battery life, you are not gonna use that in high temperatures are you?

Agree with Wayne and Brett. I've used mine for years in warn and cold weather. Works great to keep the battery topped up.

Tremendously. To mitigate I make sure everything unnecessary is turned off before charging (reduce internal heat generation) and stick it in front of a fan (works well on the clock since my fans on my night stand.) it stays Pretty chilly naked though something about the distance of the coils and power over inductance more distance more hest/power required to drive the coils.

No, it will stay charged for a for a good 6 weeks without being used in moderate weather. For the first 2 years I owned mine, I left it outside in the cab of the truck during the winter (which I think I should not have done) now this third winter I find it not hold a charge very well left outside during the winter months. It has a charger for the vehicle but that charger will not automatically cut off when fully charged which could overcharge the booster pack -- may hurt the rechargeable batteries; the AC wall charger will automatically cut off when the booster pack fully charged. Now last summer I was able to do 2-3 vehicles before having to recharge the booster pack. I hope I have answered your questions

I have these battery for a few years, it is great, with the purchase got the charger with the adapters. I take long vacations and with two of these battery I have no problem. I found that the regular in cold weather they discharge and after a few pictures you need to change the regular baterries. I hope tis is helpful.

Batteries are problems at low temps as you probably know. This link (http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA239115) tells you more than you would care to know.But electronic devices in general, it seems to me, scoff at low temperatures. So it seems if you don't find someone with actual experience, the odds should favor this device working.

It has worked well in temps below 50 f. I have not run it any colder yet but I feel it should have no problems. It starts instantly.

Not really. Sometimes I have to move/shake the charger pack (were the light that turns green is) so the light actually shows it's charging. Note that the manual says you should charge the battery periodically during the winter and allow it to be completely empty - it can damage it. Think of it like a car's battery - it charges when you run the car and if it goes completely empty you may need a new one

I use the Ctek 7002 to maintain my 2 boat batteries over the winter. I bought it for maintenance and trickle charging as my batteries were not discharged very much when I connected them last fall. I can't speak to charging of a heavily discharged battery, but for my application the charger is slightly warm, but not what I would call hot. It sits on a fabric surface in my basement and has shown no issues.

I live in az... So cold weather for us is 35f.... It does state in the manual not to operate below about 30ishF (I remember reading it).... As far as tripping breakers: it works fine on a 15A 110v circuit witha stereo plugged in as well.... So maybe it pulls 10A peak when it starts at most... Hope this helps...

I have not had an issue with this unit overheating. I have taken it from NYC to London, to Sri Lanka to Malaysia, and no problems. It works fine and charges my phone over and over again before having to recharge the Universal External Unit.

It seems to. I leave it charging overnight and to my knowledge nothing wrong happens. What I don't like is the charger remains warm, maybe 100-110 deg F, when it is disconnected from the battery , but still plugged into the wall outlet.

Should be no problem. I have the Battery Tender Junior .75A charger and the folks at BT said it would be fine. Since I live in Texas I get to ride a lot during the winter but those days or weeks when I can't, it works fine. If you want to be sure just call the folks at BT (Battery Tender).
