8/14/2023 0 Comments Best aa batteries in cold weatherGenerally speaking, you should go for alkalines for most of your battery needs but opt for lithium's for digital cameras or other high-drain products where you need a reliable high charge for as long as possible.ġ. ![]() The only negative? They’re significantly more expensive. They can also be up to 9g lighter than the equivalent alkaline AA battery, which counts when you have something powered by four AAs. While normal alkaline AAs struggle below 0☌, lithium batteries will operate down to -40☌. They last much longer, have an epic shelf life, don’t discharge as much power when not in use and can cope with extreme temperatures. Lithium: Lithium batteries work even better than alkalines. Technical advances have also seen the major problems – a short shelf life and a propensity to leak – reduced or even fixed. They’re cheap and very easy to find, and last much longer than the old zinc chloride batteries. They’re cheap as chips when bought in bulk and fine for low-drain gadgets such as a remote control, but you’ll go through them quickly on anything more demanding.Īlkaline: The mainstream battery technology for high-drain devices. Zinc chloride: This used to be the general-purpose battery of choice, but alkaline batteries are now so cheap that you don’t often see them. Today’s disposable batteries break down into three basic types: For some purposes – when you’re powering low-drain devices such as a clock or remote control – the differences aren’t that important, but with high-drain devices like a camera, game controller or anything with a lamp, screen or motor, you could see huge differences in lifespan and reliability. Different manufacturers use alternate chemistries and processes to make the batteries, largely affecting how much power the battery can supply, how long it lasts and how fast it loses energy while not in active use. You can also put the player in your glove for faster warming.AA batteries might be cheap and cheerful, but that doesn’t mean they’re all the same. Note where the battery is located on a device and make sure it’s facing your body when you put it in your pocket. While it might be a hassle to fiddle with a device buried under a jacket, your body heat will considerably lengthen battery time. “Get it under a couple layers,” Larsen says. Once you start losing bars, the battery life rapidly deteriorates, Larsen says. It’s importance of get as much charge as possible into the battery, even though it might shorten the overall lifespan of rechargeable units. ![]() Top off the charge before heading out into the cold. Even though they tend to be more expensive, lithium batteries are lighter and will perform better in the cold. Swap out your standard AA or AAA batteries for lithium ones. “It’s a really important part of the trip.” He’s currently training for an unsupported North Pole expedition during which he’ll encounter temperatures around 55 degrees below zero.Īll that said, Larsen’s tips on keeping devices charged in the cold should be more than adequate to get you through another polar vortex. “It’s great to have your head fill up with a sound rather than crunching snow and stress,” Larsen says. Batteries power his music player, which helps him maintain sanity while trudging ten hours a day through the world’s most extreme environments. Larsen carries an SOS and tracking beacon with him at all times, and he needs juice to run his electronics in case of an emergency. The Boulder, Colorado-based adventurer has skied both the North and South Poles and has spent up to 72 days on ice in temperatures that didn’t get warmer than 30 degrees below zero. Polar explorer Eric Larsen is no stranger to extreme cold.
