Operating Precautions
Before you use the battery pack for the first
time, charge it fully.
Full Charging Time: Approx. 90 minutes
(Based on Canon’s standard testing method with
the Compact Power Adapter CA-PS100E. )
➤ Charge times will vary with ambient tempera-
tures and battery charge states.
➤ To prolong the life of the battery pack and
prevent deterioration of performance, do not
charge for more than 24 hours at a time.
• Recharging before the battery pack is fully
discharged may diminish the capacity of the
battery. If this should occur, you may restore
it by fully charging and discharging it.
• The capacity of battery packs left unused
for long periods (more than 1 year) will be
shorter than normal immediately after use
is resumed.
Appendix A continued....2/4
The capacity can be restored by fully
charging and discharging the battery
pack several times.
• Replace a battery pack if it repeatedly fails to
record the rated number of images after being
charged the specified length of time.
