Why the battery in the cold is discharged faster?

When it’s cold on the street, the technique can bring in the most inopportune moment. Fully charged gadget battery suddenly turns out almost at zero. The reason in the electrolyte is a substance that conducts electric current.

The battery consists of electrodes immersed in electrolyte. There is a reversible chemical reaction between the electrodes, which results in an electromotive force that causes the battery to work. At low temperatures, the electrolyte is thick and can crystallize, which reduces the area of ​​its contact with the electrodes. Therefore, the rate of chemical reactions of oxidation and recovery decreases. The battery controller recognizes it as a decrease in capacity and displays its discharge. However, it is not necessary to think that in the cold the battery will immediately sit down. Just cut the duration of her work.

Why the battery in the cold is discharged faster

If the battery with the minimum, it would seem, to transfer the charge from the cold to heat, it will still work for a while. But charging the battery in the cold can lead to what it fails. This time com.

The temperature is optimal for the device, depends on which its battery is made. So, for the lithium-ion work zone ranges from +2 to +25 ° C, for lithium-polymer – from -20 to +35 ° C, but such batteries are more expensive.
