But just as heat speeds up chemical reactions,
cold temperatures slow them down
. That's why you might feel your battery can become sluggish in winter, even though its state of charge may remain unchanged. At colder temperatures, the battery's ability to provide sufficient power to start and run a vehicle is diminished.
How cold is too cold for batteries?
A fully charged battery can resist incredibly cold temperatures. (The thermometer has to read
-80 F
to freeze a fully charged battery.) But that strength disappears if your battery wears down enough. If your battery is only half-charged, it could turn to a block of ice at -10 F overnight.
Is cold Temperature bad for phone batteries?
Phones and cold weather generally don't get along too well.
Low temperatures can rapidly drain your phone's battery life
, and — as you've probably experienced — cause your phone to shut down altogether.
Is cold or heat worse for batteries?

high summertime temperatures
pose a greater threat to battery longevity than wintertime lows. That's because, while battery capacity is higher in the heat, high temperatures shorten overall battery life.
How do I stop my battery from draining in cold weather?
- Keep the phone in your pocket as much as possible. Your body heat will keep the device warm.

anything below 32 degrees
– its performance will likely suffer. Frigid temperatures can cause your touch screen to become unresponsive, the battery to drain more quickly and your phone can shut down unexpectedly.
What temperature is bad for batteries?
The standard rating for batteries is at room temperature 25 degrees C (
about 77 F
). At approximately -22 degrees F (-30 C), battery Ah capacity drops to 50%. At freezing, capacity is reduced by 20%. Capacity is increased at higher temperatures – at 122 degrees F, battery capacity would be about 12% higher.
At what temperature do car batteries fail?
Cold weather slows everything down, especially the chemical reaction happening inside your car battery. In fact, at
32°F
, a car's battery loses about 35% of its strength. And at 0°F, it loses up to 60% of its strength—but your engine requires nearly twice as much power to start!
Is heat hard on car batteries?
Most people think about their car battery in the winter, but
warm temperatures are actually your battery's worst enemy
. Hot weather means high temperatures under the hood, which accelerates corrosion inside the battery.
At what temperature do AA batteries freeze?
According to Sanyo's datasheet (PDF), basic AA Eneloops are only rated down to
0°C/32°F.
Any colder than that and you can probably expect to see greatly reduced performance in medium and high-drain flashlights and devices. Lithium batteries, on the other hand, perform quite well when it's cold out.
Why do phones lose battery in the cold?
When lithium-ion batteries are exposed to cold temperatures, their performance suffers. When cold, a phone
battery can drain faster than normal

– its performance will likely suffer. Frigid temperatures can cause your touch screen to become unresponsive, the battery to drain more quickly and your phone can shut down unexpectedly.
What is the optimal temperature for charging a battery?
Batteries can be discharged over a large temperature range, but the charge temperature is limited. For best results, charge
between 10°C and 30°C (50°F and 86°F)
. Lower the charge current when cold.
