Attention: The engine must not be run with the battery disconnected, as Otherwise, parts of the electrical equipment may be damaged.
Precautions: never bridge the positive and negative battery terminals. If a short circuit occurs, the battery will heat up and may crack. Do not use open flame near the battery. Battery electrolyte is very corrosive. It must not come into contact with eyes, skin or clothing and, if necessary, wash off the electrolyte with water.
The battery is also charged in the installed state, but both wires must first be disconnected.
Attention: This will erase data from the injection system control unit, as well as codes and settings from the radio transmitter.
Before charging, check the electrolyte level and, if necessary, top up with distilled water.
Frozen batteries must be thawed before charging. A charged battery freezes at about -65°C, a half-charged battery freezes at about -30°C, and a discharged battery freezes at about -12°C.
♦ Remove the battery plugs or pry them off with a small screwdriver and place the plugs over the holes to prevent electrolyte splashes on the paint during charging.
Charge the battery only in a well ventilated area. When charging the installed battery, keep the hood open.
Connect the charger wires to the battery terminals, observing the polarity.
The temperature of the electrolyte during charging should not exceed 55°C, if necessary, stop charging or reduce the charging current. If the battery has been discharged for too long, it can no longer be fully charged, and sometimes not at all. In these cases, it is necessary to charge the battery for a very long time with a low current and, finally, check the density of the electrolyte.
♦ During normal charging, the charging current is approximately 10% of the battery capacity (for a 50 Ah battery - about 5 A). Charging time will be approximately 10 hours.
♦ Charging continues until all cans are gassy (hydrogen) and inside will not be strong «boiling», and during three consecutive measurements with an interval of 1 hour between them, the density of the electrolyte and the voltage of the battery will not increase.
♦ After charging, check the electrolyte level and, if necessary, top up with distilled water.
♦ Check electrolyte density. If in one of the jars the density value is noticeably lower than in others (for example, in 5 jars - 1.26 g / ml, and in one - 1.118 g / ml), the battery is defective and must be replaced.
♦ Wait 20 minutes for all gases to escape from the battery, then replace the plugs.
