The density of the electrolyte poured into the battery is directly dependent on the temperature. The lower the degree of its heating, the lower the density of the electrolyte. And the lower the specified parameter, the lower the battery capacity. Therefore, reducing the heat loss of the electrolyte helps to conserve the charging energy of the starter battery.
Necessary
polyurethane foam - 1 cylinder

Step 1
Starting the engine on a frosty winter morning is much easier if the battery is removed from the car at night and placed in a warm room. In cases where such a measure was not taken by the owner, and he left the battery to spend the night in the car, and in the morning the starter did not have enough energy to successfully start the engine, it is enough to remove the battery from the car and immerse it in a container of hot water. Within an hour, a seemingly extremely discharged battery will be able to release so much energy to the starter that it will rotate the engine crankshaft with frantic force.
Step 2
The listed facts suggest that for successful operation in winter, much more attention should be paid to the issue of battery insulation than is commonly believed.
Step 3
The best option for thermal insulation of the specified power unit would be to cover the walls of the battery socket with polyurethane foam, which is sold in aerosol stores in hardware stores. When applying foam on the bottom and walls of a niche intended for a battery, it must be borne in mind that when solidifying, the volume of the applied chemical increases threefold.
Step 4
After about two hours of time, the excess of solidified polyurethane foam is cut off with a knife, after which the battery takes its regular place, and on top it is closed with a cover made of foam. The creation of such a "coat" will help keep the electrolyte in the battery warm for 8-10 hours. That will allow you to start the car engine, regardless of the ambient temperature.
