Battery Charge Duration
9.6.2 Battery Charge Duration
A fully discharged battery can take up to 4 hours to charge. The quad battery charger
stops applying power to the battery when it is fully charged
– there is no risk of
overcharge if the battery remains in the charge well. The 75% charge indicator is
handy if you need a quick recharge
– a quick charge often takes less than one hour.
9.6.3 Charge Indicators–The LEDs
Each battery charge well is equipped with an LED to indicate the charge status of
the battery. When a battery is inserted in the charger, the colour and behaviour of the
LED associated with the charge well in use indicates the status of the charge. Refer
to Table 9.3 on page 290 for details.
9.6.4 Troubleshooting
9.6.4.1 Excessive Charge Duration
The charger is equipped with a recalibration function – a function that fully
discharges and then fully recharges the battery. This process is necessary to
recalibrate the battery capacity gauge internal to the battery. The charger attempts
recalibration when:
• the battery capacity is at less than 30%, and
• the battery has undergone more than 40 partial charge cycles since the last
full discharge.
The recalibration function extends the charge time by up to 2 hours.
9.6.4.2 Indicator Flashing Red
If the indicator flashes red:
• Remove all batteries and disconnect the mains power cable.
• Wait at least 20 seconds, and then plug the cable in again.
If any of the charge well LEDs continue to flash red, the charger is defective and
requires service. If all indicators are flashing red, there is a power supply problem
and the charger requires service.
9.6.4.3 Power LED Does Not Light Up
• Remove all batteries, and unplug the charger.
• Connect another device to the mains outlet to ensure there is power.
• Remove the IEC mains power cable from the charger, and check it for damage.
