Canon EOS-1D Mark IV - Manual (Page 31)

Charging the Battery
7 All Three Charge Level Indicators Blink
• If all three Charge level indicators blink in green, it means that the
battery's internai temperature is not within 0°C - 40°C / 32°F -104°F.
The battery will start recharging when the internai temperature is
within 0°C - 40°C / 32'=F - 104°F.
• If all the Calibration (discharge) status indicators blink in red or if all
the lamps blink in red and green (including the <CAUCHARGE>
lamp), remove the battery from the charger and take it to your dealer
or to nearest Canon Service Center.
• Also, if a battery other than Battery Pack LP-E4 is attached to the
charger, the lamps will blink in red and green (including the <CAL/
CHARGE> lamp) and the battery cannot be recharged.
»
The charger cannot charge any battery other than Battery Pack LP-E4.
Battery Pack LP-E4 is dedicated to Canon products only. Using it with a
non-Canon battery charger or product may result in malfunction or
accidents for which Canon cannot be held liable.
1^ • When two battery packs are attached to the charger, the battery attached
first will be charged first, then the other battery will be charged.
Although one battery can be recharged and another calibrated at the same
time, two batteries cannot be recharged or calibrated at the same time.
• For battery calibration, it is best to do it after the battery is nearly
exhausted. If you do the calibration with a fully charged battery, it will
take approx. 12 hours to complete the calibration and the battery
recharging (approx. 10 hours to discharge, and approx. 2 hours to fully
recharge).
