Attention: Never close the battery terminals! In the event of a short circuit, the battery heats up and may burst. Do not approach the battery with an open flame During the reactions that occur in the battery, hydrogen is released, which can explode. Electrolyte acid is very caustic, so it should not be allowed to come into contact with eyes, skin, or clothing. If the acid spills, immediately wash it off with plenty of water.
The battery can only be charged in a well-ventilated area. While charging the battery in the car, you need to open the engine hood.
1. Disconnect the wires from the battery.
2. Before charging, check the electrolyte level and, if necessary, top up with distilled water.
3. Defrost a frozen battery before charging.
4. Unscrew the threaded plug from the battery and place it on the hole, so that the gases formed during charging can escape. If the plug is not unscrewed, the battery will crack, as the air and gas removal channel may be clogged in the plug.
5. During normal charging, the charging current is approximately 10% of the battery capacity (with a capacity of 45 A / h, the charging current can be 4.5 A), the charging time is then 10 hours.
Attention: The rectifier must not be connected for longer than 1 day, as otherwise a lot of explosive gases are formed, and water from the electrolyte evaporates.
6. The positive pole of the battery must be connected to the positive pole of the rectifier, and the negative pole of the battery to the negative pole of the rectifier.
7. During the charging period, the temperature of the electrolyte should not exceed 55 * C, otherwise it is necessary to interrupt the charging (wait until the temperature drops and charge again), reduce the charging current.
8. It is necessary to charge until gas is intensively released from all cells, and also until, after three measurements at an interval of 1 km / h, the mass inherent in the electrolyte does not change and the voltage no longer increases.
9. It is allowed to charge the battery using fast charging equipment, but its frequent use is unacceptable.
Batteries in a discharged state that have not been used for a long time, or new ones, should not be charged quickly.
10. After charging is completed, it is necessary to check the electrolyte level, if necessary, top up with distilled water.
11. Check electrolyte density. If the density value measured in one cell is significantly lower than in the others, then the battery is damaged and must be replaced.
12. For about 20 minutes, allow the gas to escape from the battery cells, and then tighten the plugs.
Attention: The engine must not be running with the battery disconnected, otherwise the diodes in the generator may fail.
