To protect the battery and prevent a decline in performance, do not charge it
continuously for more than 24 hours.
• This is a lithium ion battery pack so there is no need to completely use
or discharge it before recharging.
• It can be charged at any charge state.
• It takes approximately 2 hours 30 minutes to bring a depleted battery
pack to a full charge state (based on standard Canon testing criteria).
• Charge it within a temperature range of 5 to 40 °C (41 to 104 °F).
• The charging time varies according to the ambient temperature and
charge state.
• You are advised to charge the battery on the day of use, or one day
before, to ensure a full charge.
• Even charged battery packs continue to discharge naturally.
• The battery life should be considered over when the usable time is
severely limited even after the prescribed charging time.
• Replace it with a new battery.
