In cold weather, motorists are often faced with the fact that the car cannot be started due to a dead battery. If this situation repeats constantly, you need to check the battery for performance.
Car batteries are serviceable and maintenance-free. What is their difference. Serviced batteries can be refilled with fluid. In the warm season, it is better to fill the battery with distilled water. Cold - electrolyte (sold in spare parts stores).
How to understand that there is enough liquid in the battery? You can measure the density of a liquid using a special device - a hydrometer. It is because of the low density of the electrolyte that the serviced battery freezes in winter. If this happens, remove the battery from the car, take it to a warm place, add electrolyte to the required level and connect it to the charger.
If these measures do not help, check the date of manufacture of the battery. The service life of the battery being serviced is no more than 5 years with gentle operation. If the car has a high mileage, the battery life is almost halved.
The maintenance-free battery lasts much longer - up to 8 years. But you cannot pour liquid into it. If in cold weather it began to "junk", this suggests that it is time to change it to a new one. A maintenance-free battery can be identified visually - there are no special screw caps on it, it is tightly sealed.
