I have an outdoor thermometer that had been working for about 4.5 years before the battery finally died. I replaced it, and after a few days we had some colder weather that seems to have killed the battery, as the sensor is no longer transmitting the temperature. Do different types of batteries (or battery chemistry) work better in the cold than others?
In: Chemistry
Look for lithium AA batteries, rather than the typical alkaline batteries. The lithium ones cost a bit more, but they can withstand much-colder temps than alkalines.
The answer is: yes, chemistry. This is a big part of how battery companies compete.
Pick your favorite characteristics of batteries:
* cold temperature performance
* longevity
* power (aka the ability to support high bursts of power)
* rechargeability
* reliability (as in, not prone to leaking, spontaneously combusting, etc.)
* price
You get two, maybe three…..if you get four, buy that battery. That’s the battery market, they have different goals, and if you add in the profit motive of the manufacturer, that’s basically the landscape you are dealing with. Like so many things in life, there are tradeoffs.
