You are recommended to use it in the camera until it is completely discharged and to store it in an indoor location with low relative humidity and between the temperatures of 0 – 30 °C (32 – 86 °F).

Storing a fully charged battery for long periods of time (about one year) may shorten its life cycle or affect its performance. If you do not use the battery for long periods of time, charge it fully and discharge it fully in the camera about once a year before returning it to storage.

Charging the Battery

Use the supplied camera station and compact power adapter or Battery Charger CB-2LV/CB-2LVE (sold separately) to recharge Battery Pack NB-4L.

Since this is a lithium-ion battery, you need not completely discharge it before recharging.

It takes approximately 1 hour 30 minutes to fully charge the battery from a depleted state (based on Canon’s testing standards).

•Charging it within a temperature range of 5 – 40 °C (41 – 104 °F) is recommended.

•Charge times may vary according to the ambient temperature and the battery's 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 batteries continue to discharge naturally.

If the performance of the battery diminishes substantially even when it is fully charged, its life has been exceeded and it should be replaced.
