cold weather performance? how well do these AA batteries hold up in colder temps (around 8*F at night) compared to alkaline batteries?

I am using Rayovac Rechargeable Hybrid NiMH Batteries in my La Crosse Technology TX29U-IT 915 MHz Wireless Temperature Sensor. They gave absolutely no problems over the past three winters. Last week the outdoor temperature was aound 0 degree F (-18 degree C) at night. NiMH cells have much better performance than alkaline cells at cold (below 0 C). Most NiMH manufacturers spec their discharge temperature range down to -10 C. Sanyo Eneloop are spec'd down to -20 C. That does not mean they will fail at -21 C, just that performance will suffer more at lower temperature.

I used this battery at about 25F. Battery was in an outside pocket, so it was cold. Seemed like instead of 5 to 8 hours of shooting, I got only 4. I searched literature, and I found a guy who did some engineered tests. At temperatures in the range of 20-32F, he measured a 15% drop in number of shots. The battery should be brought up to a more normal temperature and recharged. Place in inside pocket next to body heat.

To tell the truth, I have used both rechargeable and regular name brand batteries. We've got cold weather here for at least half the year, and the rechargeables didn't last as long. We use it on our outside porch. I bring it in when it's going to be cold, and that saves either kind of battery. I love this product!

Yes they work well for me and they do not get too warm when the light is set on High, heat shortens the life of rechargeables. Rechargeables are also less likey to cause corrosion than alkalines when they are drained.

We had a mild winter here in NW Wisconsin, but my camera worked fine. We were down to 0 degrees with no problems and the same batteries were in it all winter.

All of the batteries are still connected and installed in the various vehicles. I've been using it for about two months in fairly cold weather without any issues. Works as stated--so far, so good.

I have had mine for over a year now and they are still fine.A lithium-Ion battery shouldn't really go bad.Thay don't have a charge memory where they loose capacity every time you use them..Just don't leave them out in the cold and not charged because that does seem like it can mess them up and don't recharge until they have cooled off..

Can't speak for MI as I live in CO but it gets pretty cold here and batteries seem to last about 3-4 months in winter and longer in other quarters so I end up changing them twice a year on average.

they're just like other lead-acid batteries and will lose their charge quicker in the cold and also sustain damage. i suggest you find a warmer indoor place for your battery. if you're using it at a ski chalet you can either hook a heater up to keep it warm when you're not there, or just transport it around with you. remember tho it's quite heavy

According to Panasonic these cells will work up to -4F. Hard to say whether it will work in your trail camera at those temps as cold weather is hard for any battery. Another option is to use lithium cells but don't know if the higher voltage is safe for your camera.

I have owned 3 of these radios and I just use a good quality battery like "Energizer" or Duracell and it seems to work fine. Some people like "Phillips" batteries from Europe but I have not noticed any change in performance by using different batteries. An alkaline battery will probably give you longer life, but it plays for a long time on any battery.I play mine mostly on AC.This radio is well worth the money since it does not cost very much to begin with. I only paid $30 from Amazon Prime.Jim Wilder, Bradenton, Florida

I don't think ambient temperature has any effect on performance of Battery Tender. I like to plug my daily driver in to the Battery Tender after I'm done using the car for the day, especially if I don't expect to use the car for several days. I believe this will/may increase my battery's longevity, and I have no battery concerns when the winter temperature dips low.

It worked in 30F weather today. The only reason it wouldn't work in really cold weather would be if the battery freezes.

I have 4 of them in operation irunning in a solar garden light and Tikki bar light set up. The batteries have worked flawlessly even with extremes of temperature ranging from 15F to 120F. The oldest battery I have is 2 years and is performing the same as it was on day 1. I am very happy with these batteries.

It has worked fine in the cold and I'm in North Idaho. Battery life is reduced, but that would be the case for anything that uses batteries. As far as water resistance goes, I've tried to keep it sheltered so I can't tell you.

Double A work great. I bought Lithium AA's due to fact the transmitters are across street from my house, in a building w no power; and more durable in cold weather.

I am using two units on my RV, one for the coach batteries and another for the chassis batteries. The RV is outside and our temps got down to +14 deg F last week. There does not seem to be any problem with them operating at least down to that temp.
