Appendix Battery Handling Battery Status Indications The following icons or messages indicate the battery status on the LCD monitor. Battery charge is low. Recharge it as soon as possible if it will be used for an extended period. Change the battery pack Battery charge is insufficient to operate the camera. Replace the battery immediately. Battery Performance (p. 139) Battery Handling Precaution ‹ This is a rechargeable lithium ion battery pack so there is no need to completely use or discharge it before recharging. It can be recharged at any time. ‹ It takes approximately 90 minutes to bring a fully discharged battery pack to full charge (based on Canon's testing standard). Charging it 11 within a temperature range of 5 - 40 °C (41 - 104 °F) is recommended. Appendix Charge times may vary according to the ambient temperature and the battery's charge state. ‹ The use of the separately sold AC Adapter Kit ACK-DC20 is recommended to power the camera during long usage sessions (p. 128). z Keep the battery terminals clean at all times. Dirty terminals may cause poor contact between the battery and camera. Polish the terminals with a soft cotton swab before charging or using the battery. z Do not shake or place the battery charger upside down once the camera battery is in it, as this may cause the battery to fall, damaging it. z Although the battery pack's maximum operating range is 0 to 40 °C (32 to 104 °F), the optimal range is 10 to 30 °C (50 to 86 °F). At cold temperatures, such as those experienced when skiing, performance will temporarily decline, reducing the usable time before recharging. Under these conditions, revive the battery by warming it in a pocket immediately before use. However, ensure that there are no metallic items in the pocket that could cause a short circuit, such as a key ring, etc. 125
