Appendix 207You may be able to check the charge state depending upon how theterminal cover is attached (Fig. C, D).z You are recommended to use it in the camera until it isdepleted and to store it in an indoor location with low relativehumidity and between the temperatures of 0 – 30 °C (32 – 86°F).Storing a fully charged battery for long periods of time (about oneyear) may shorten its life cycle or affect its performance. If you donot use the battery for long periods of time, charge it fully anddischarge it in the camera about once a year before returning it tostorage.Charging the Batteryz Since this is a lithium-ion battery, you need not discharge itbefore recharging.z It takes approximately 2 hours 5 minutes to fully charge thebattery from a depleted state (based on Canon’s testingstandards).• •Charging it within a temperature range of 5 – 40 °C (41 – 104 °F)is recommended.• Charge times may vary according to the ambient temperature andthe battery's charge state.z You are advised to charge the battery on the day of use, or oneday before, to ensure a full charge.• Even charged batteries continue to discharge naturally.z If the performance of the battery diminishes substantially evenwhen it is fully charged, its life has been exceeded and itshould be replaced.Fig. CCharged BatteryFig. DSpent BatteryAttach it so the Sis visibleAttach it the oppositeway to Fig. C.EC231CUG-E.book Page 207 Thursday, June 7, 2007 10:22 AM
