Attention! When charging a maintenance-free battery, items marked with (, do not need to be performed. SCENIC vehicles are equipped with a completely maintenance-free battery.
- Never short-circuit a battery, i.e. do not connect positive (+) and negative (-) poles. If a short circuit occurs, the battery will heat up and may burst. Do not light it with open fire. The electrolyte is corrosive. Avoid contact with eyes, clothing or skin. Wash it off with plenty of water if necessary.
- Disconnect the power cable terminals from the battery. starting at the wire terminal «masses» (-) before connecting it to the charger.
- Check the electrolyte level before charging the battery. If necessary, add distilled water to the cells.
- Let the battery thaw if it is frozen. A fully charged battery freezes at about -65°C, a half-discharged battery freezes at -30°C, and a fully discharged one freezes already at a temperature of about -12°C.
A discharged battery cannot be fully charged using a conventional charger. In this case, you should use an electronic charger that does not allow the battery to be charged to become very hot.
- Check the open circuit voltage before charging the battery.
Before charging, unscrew the plugs of the battery cells and place them on the holes. In this way, splashing of the electrolyte caused by gases formed during charging is prevented.
- Charge the battery only in a well-ventilated area. When charging an installed but disconnected battery, leave the car hood open.
During normal charging, the charging current should be about 10% of the battery capacity. This means that for a battery with a capacity of 50 Ah, the charging current should be about 5 A. The battery charging time is approximately 10 hours.
- Connect the positive pole of the battery to the positive pole, and the negative pole to the negative pole of the charger.
- The temperature of the electrolyte during charging should not exceed +55°C. If necessary, interrupt charging or reduce the charging current.
.Charge the battery until intense gas formation in all cells stops, and until the increase in electrolyte density and voltage stop. These indicators are compared by measuring the density of the electrolyte three times, performed at an interval of 1 hour.
Check the electrolyte level after charging is complete. Add distilled water if necessary.
Check electrolyte density. If in one or two adjacent cells the density is significantly lower (for example, in 5 cells the density is 1.26 g / ml, and in one - 1.18 g / ml), the battery is defective and must be replaced.
Let the battery stand for about 20 minutes before screwing in the plugs.
Attention! Do not start the engine with the battery disconnected. This will damage the electrical system.
