Connecting a home charger
1. Connect the positive wire of the charger to the positive of the battery, the negative wire to the negative of the battery.
2. When charging, the battery can remain installed in the car.
3. If the home charger is weak, then the battery wires can not be disconnected.
4. Battery caps may remain screwed on. The gas generated during battery charging can be vented through the vents in the plugs.
5. The charging current should be approximately 10% of the battery capacity at the beginning (e.g. 7 A with a 70 Ah battery) and automatically decrease while the battery is charging.
6. The battery is considered fully charged if the density of the acid in it does not increase within two hours.
7. During battery charging, distilled water partially decomposes. Gas bubbles are formed from hydrogen and oxygen - an explosive gas with a high explosive ability.
8. Therefore, you need to take care of good ventilation of the room, especially if the battery is charged with a powerful current.
9. When charging the battery, do not smoke near it and use open fire.
10. The oxyhydrogen gas can also be ignited by sparks generated by connecting and disconnecting the charger or wires.
