Recharging The Battery; Charging - Canon EOS 1D Mark III Instruction Manual

Recharging the Battery

The charger cannot charge any battery other than Battery Pack LP-E4.
Battery Pack LP-E4 is dedicated to Canon only. Using it with a non-Canon battery charger
or product may result in malfunction or accidents for which Canon cannot be held liable.
For battery calibration (p.28), 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 about 12 hours to
complete the calibration (power discharge) and the battery recharging (approx. 10
hours to discharge, and approx. 2 hours to fully recharge).

It takes about 2 hours to fully recharge a
completely exhausted battery. The time
required to recharge the battery depends on the
ambient temperature and battery's charge level.
When two battery packs are attached to the
charger, the battery attached first will be charged
first, then the other battery will be charged.
