COMPLETION OF CHARGING: Charge
completion is indicated by the CHARGED (green) LED; when lit, the charger has stopped charging and switched to the Maintain Mode of operation.
MAINTAIN MODE: When the CHARGED (green) LED is lit, the charger has started Maintain Mode. This mode of operation is also known as
GENERAL CHARGING NOTES:
The unit is designed to control its cooling fan for efficient operation. Consequently, it is normal for the fan to start and stop when maintaining a fully charged battery. The fan does not run in Tester Mode.
If the charge mode is changed after charging has started (by pressing the CHARGE RATE or BATTERY TYPE button), the charging process will be restarted.
The voltage displayed during charging is the charging voltage and usually will be higher than the battery’s resting voltage.
CHARGING TIPS
Read this entire manual before using your charger. The tips below serve only as a guide for specific situations.
If your vehicle won’t start: You don’t need to fully charge a battery to start your vehicle. If the charger won’t start your vehicle using the 70A START rate, try charging the battery using the 20A rate for 10 or 15 minutes. That should charge the battery enough to allow the 70A START rate to start the vehicle. If the vehicle will then be operated continuously for an extended period (such as a long drive), the vehicle could charge the battery back to normal during that period. If the vehicle will only be operated for a short period (short drive), the battery might need to be charged again before it could start the vehicle again.
Reviving your battery: If you only wish to charge your battery enough to operate your vehicle, you don’t need to wait for the entire charging process to be completed. When the charger displays a battery % of 77 or more (see page 14), the battery has usually been charged enough for the vehicle to start and operate normally.
Completing an interrupted charge: If the charging process has been inter- rupted and restarted after the charger displays a battery % of 85 or more, the charger could go straight to Maintain Mode (see top of this page). However, if the original charge was started using 20A, the charge can often be completed using the 2A rate.
