Connecting the charger
Connect the positive wire clamps to the positive terminal of the battery, the negative wire clamps to the negative terminal.
The battery wires do not need to be removed if a do-it-yourself charger is available.
Battery plugs can not be turned out. The gas generated during charging can escape through the vents that are in the plugs.
The charging current should initially be about 10% of the battery capacity (e.g. 6.3 A for a battery with 63 Ah). During the charging process, the current automatically decreases.
The battery is considered fully charged if the density of the acid does not increase further within two hours.
When the battery is charged, the electrolyte partly decomposes. Hydrogen bubbles are formed, which, when mixed with air, forms an explosive detonating gas.
It is necessary to take care of good ventilation of the room if the battery is charged with a large electric current.
When the battery is charging, do not smoke nearby. It is not allowed to have an open flame near the battery.
The explosive gas can ignite even sparks that appear when disconnecting or connecting the terminals of the charger or battery cables.
Fast battery charging
If someone is in a hurry, can quickly charge the battery in the workshop. In an hour, the battery will be ready. Pay attention to the following:
- An older battery due to fast charging can permanently fail. Then a new battery is urgently needed.
- Both battery cables must be removed. Due to the high charging current, very sensitive electronic components of the vehicle may be damaged.
- Unscrew the battery plugs, as the battery releases a significant amount of gas during rapid charging.
