It can range from 5 to 25 milli- OPERATION If a vehicle will not be operated for approximately a 20 days, the IOD fuse should be pulled to eliminate CHARGING TIME REQUIRED DESCRIPTION WARNING: NEVER EXCEED 20 AMPS WHEN CHARGING A BATTERY WITH A TEMPERATURE The time required to charge a battery will vary depending upon the following factors. SIZE OF BATTERY A completely discharged large heavy-duty battery may require more recharging time than a completely OPEN CIRCUIT VOLTAGE CHARGING 5 AMPS 10 AMPS 20 AMPS 12.25 TO 12.49 6.0 HOURS 3.0 HOURS 1.5 HOURS 12.00 TO 12.24 10.0 HOURS 5.0 HOURS 2.5 HOURS 10.00 TO 11.99 14.0 HOURS 7.0 HOURS 3.5 HOURS BELOW 10.00 (Refer to 9 Charging A Completely Discharged Battery”) 18.0 HOURS 9.0 HOURS 4.5 HOURS * Charging voltage not to exceed 16.0 volts TEMPERATURE A longer time will be needed to charge a battery at -18°C (0°F) than at 27°C (80°F). When a fast charger CHARGER CAPACITY A charger which can supply only five amperes will require a much longer period of charging than a STATE OF CHARGE A completely discharged battery requires more charging time than a partially charged battery.
