Note: The following procedure is a recommendation. Always follow the manufacturer's instructions.
13. This type of battery takes longer to fully charge than the normal type. The time depends on the degree of discharge of the battery, but can last up to three days.
14. A constant voltage charger with an output voltage of 13.9 to 14.9 volts and a charging current of up to 25 amps is required. Using this method, you can charge the battery to 12.5 volts in three hours, but this only applies to partially discharged batteries. A full charge takes much longer.
15. If the battery is to be charged from a completely discharged state (voltage at terminals below 12.2 V), entrust this task to workshop specialists, since it is necessary to constantly measure the charge level.
