Does the Battery Get Frozen? How is it Affected by Weather Conditions?

Yes, the battery can get frozen.

Freezing degree of a fully charged battery is in the range of -50oC and -70oC. In other words, under normal conditions, a properly charged battery does not get frozen. However, the discharged batteries may even get frozen in the range of 0oC and -10oC depending on to which extent they have discharged. Make sure that the batteries are properly charged particularly on cold days.

Effects of the weather conditions on the battery:

1. In terms of storage:

Store the battery indoor. If you store it outdoors, dust and precipitation will increase discharge. So the battery should be stored in a dry and cool place. Discharge rate of the batteries increases or decreases according to the temperature. In general, in case of each increase of 10 degrees would double the discharge. For these reasons, storage in the temperature range of 10-16 centigrade degrees would be much better than storage in the range of 25-30 centigrade degrees.

2. When battery is on the vehicle:

On hot days, the starting power of the battery increases and, consequently, corrosion on the battery also increases. For this reason, the batteries operating in the hot climate have a less shelf life. On cold days, the starting power of the batteries goes down. Additionally, the starting value of the vehicle engine also increases. As a result, the starting power of the batteries becomes important under cold conditions. On very cold days, the liquid (electrolyte) in battery has risk of getting frozen. While a fully charged battery gets frozen only at -70 centigrade degrees, a discharged battery may get frozen even at -5 centigrade degrees depending on to which extent it has discharged. For this reason, it is very important to keep the battery fully charged on cold days.
