What needs to be done with the battery for a stable start in the cold?
Every year, with the onset of cold weather, car owners have massive problems starting a car in frost. The reason is a frozen battery, which prevents the starter from starting the engine. What to do to exclude such situations, the AvtoVzglyad portal will tell you.

First of all, you should know: if you do not plan to drive the car for a long time, it is better to de-energize it. Simply put, remove the battery and store it in a dry place. Indeed, in a few weeks of cold weather, a car’s energy consumers, such as an alarm and the same audio system, will tighten the battery. And a battery that has dropped to zero may not even help revive even the “donor”, not to mention mobile starter chargers. Therefore, as mentioned earlier, it is better to prevent than to “treat” later.

With a strong temperature drop in the battery, a delay in chemical processes occurs, which can easily turn into a so-called sleep mode for the battery, when the electrical properties are actually halved. Therefore, experts recommend forcibly activating the energy consumers before starting the engine. The easiest way is to turn on the marker lights, which contribute to the resumption of electrochemical processes, or simply give the battery a power “kick”, after which it is already possible to start the car.

Short trips in the cold season are also not in your favor. The fact is that short trips mean that the generator cannot compensate for the energy loss from the battery, which is certainly not a slow but certain loss of capacity. In addition, the battery with a “minus” overboard never charges more than 80% due to the slow current from the highly electrochemical processes we talked about above. That is why it is better to drive more often and for longer.

As you already understood, almost all problems with a cold start arise from the negligence of the car owners themselves. You should constantly monitor the battery charge, and also do not ignore the possible leakage of power and failure of electrical equipment in the car. As an additional protection against the discharge of the “drive”, you can use a special thermal cover. True, even at a very low temperature or its sudden changes, it will not save the battery from “freezing” and the car from the risk of not starting.
