Checking the electrolyte level in the battery
The electrolyte level should be between the MAX and MIN marks on the outside of the battery case (Fig. 1.5). Add only distilled water as needed.
Fig. 1.5. Location of MAX and MIN marks on the battery case
The battery is divided into several cans inside. Unscrew the plug from each can and add water to the MAX mark. Do not allow the electrolyte level to overflow above the MAX mark, as it may leak out during driving and cause damage. Check the electrolyte level depending on the operating conditions of the car, but not less than once every four weeks.
If the battery is not used (the car is not driven), it will discharge itself over time. Check the battery charge every four weeks and, if necessary, charge it with a weak current.
In winter, the battery is under particularly heavy load. In addition, at low temperatures, the battery only gives off a portion of the power it has at positive temperatures when starting the engine. Therefore, it is recommended to check the battery before the winter season and recharge it if necessary.
Disconnecting and connecting wires to the battery
Before disconnecting the wires from the battery terminals, turn off the engine, then first disconnect the wire from the negative battery terminal, and then from the positive. When connecting the battery, first connect the wire to the positive terminal, and then to the negative.
Warnings
(1) Do not smoke near the battery and do not allow an open flame to be near it, as this may ignite explosive gas (electrolyte vapors generated by the battery).
(2) Battery electrolyte is extremely harmful and poisonous. Avoid contact with eyes, skin, clothing, or painted surfaces of the vehicle. Spilled electrolyte must be washed off immediately with plenty of water. If electrolyte gets into your eyes or on your skin, seek medical attention immediately.
Notes
(1) Do not disconnect the wires from the battery terminals when the ignition switch is in the ON position. This may damage the vehicle's electrical equipment.
(2) Keep the battery terminals clean. After connecting the wires to the battery terminals, apply special protective grease to the terminals. Use warm water to clean the terminals.
(3) If the vehicle is not going to be used for a long period of time, remove the battery and store it in a place where the electrolyte will not freeze. The battery must be stored only in a fully charged state.
