Electrolyte level
As already mentioned, AB is unattended. It is filled with a solution of sulfuric acid and distilled water. Because some of the water may evaporate, then periodically check the electrolyte level and, if necessary, top up with distilled water. The electrolyte level must be between the marks (2) on the AB. To top up, unscrew the caps on the cans and pour distilled water until the electrolyte level is normal.
Charged
To check the charge, a density meter is needed - a hydrometer (1). To check, unscrew the plug and insert the tip of the hydrometer through the rubber overflow protection. Use a rubber bulb to suck up enough electrolyte so that the float can float freely. In accordance with the degree of charge of the battery, the electrolyte has a different density, which is measured with a hydrometer. At a density of 1.28 g/cm3 the battery is fully charged, at a density of 1.12 g/cm3 it is completely discharged. An intermediate value corresponds to a different degree of battery charge.
AB charging
A heavily discharged battery should be filled with distilled water immediately after recharging. When charging, the electrolyte level rises and A B may "boil". The charging current at the beginning of charging should be 10% of the battery capacity. Depending on the design of the charger, the charging current may gradually decrease automatically. The battery is considered fully charged when the density of the electrolyte has not changed during the last two hours.
The stoppers of the cans must be unscrewed and lie freely on the filling holes. In this case, explosive gas can be released, which is formed when hydrogen and oxygen are mixed. Since splashes of electrolyte can splash out during an intensive charge, you need to close the space around the battery with rags. paper or the like. If charging is done indoors, it must be well ventilated. Never use an open flame near a charging battery.
When using a special charger, you can leave the battery in the car. In the case of using a fast charger, both battery wires must be disconnected so as not to damage the generator diodes, receiver, etc.
Removing and installing the battery
The battery is located in the engine compartment and mounted on the console (2), i.e. fixed on one side at the bottom with a bolt (1). Before removing, disconnect both wires from the battery (3, 5). disconnecting the negative wire first (3).
Removal is easy.
Attention: If you have a car radio with a code, you must remember the code in order to start the radio.
When installing the battery, first clean the poles (conclusions) and smear them with Vaseline. Connect the positive wire first. Different wires have terminals of different sizes to avoid confusion during installation.
Starting a car with a discharged battery
The easiest way is to use auxiliary wires, which should have a large cross-section and powerful clamps for supplying current from the auxiliary battery. First you need to connect the positive terminals of both batteries and then connect the negative terminals. On "auxiliary" car, start the engine and leave it running at medium speed so that the generator supplies additional current. Starting by towing, or by pushing the vehicle, are well-known methods of starting an engine with a discharged battery.
