Charging the Battery Pack
Use the following procedures to charge the battery pack the first time you use the camera or when the "Change the battery pack" message displays.
Battery charger model names and types vary by region.
- Insert the battery pack into the battery charger. Align the
on the battery pack and battery charger and insert it correctly.
- Align the battery pack correctly with the arrows on it and the charger.
- Battery charger model names and types vary by region.
(For CB-2LV) Plug the battery charger into a power outlet.
(For CB-2LVE) Attach the power cord to the battery charger and plug it into a power outlet.
- The charge indicator will light red while the battery pack is charging. It will change to green when the charge is complete.
- After charging, unplug the battery charger and remove the battery pack.
 To protect the battery pack and prolong its life, do not charge it for longer than 24 hours continuously. |
- Since this is a lithium-ion battery pack, you need not completely discharge it before recharging. It can be recharged at any point. However, since the maximum number of charge cycles is approximately 300 times (battery life based on Canon's testing standards), you are recommended to charge the battery pack after having discharged it completely to prolong battery life.
- It takes approximately 95 minutes to fully charge the battery pack from a fully discharged state (based on Canon's testing standard). Charging it within a temperature range of 5o to 40o C (41o to 104o F) is recommended.
- Charge times may vary according to the ambient temperature and the battery pack's charge state.
- You may hear a noise during charging. This is not a malfunction.

Battery Pack Handling Precautions
- Keep the battery pack terminals (
 ) clean at all times. Dirty terminals may cause poor contact between the battery pack and camera. Polish the terminals with a soft cotton swab before charging or using the battery pack.
- Do not rapidly overturn or wave the battery charger around when it contains the battery pack. The battery pack could fly out.
- At low temperatures, battery pack performance may be reduced and the low battery icon may appear earlier than usual. Under these conditions, resuscitate the battery pack 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 holder, etc.
- Do not place anything, such as tablecloths, carpets, bedding or cushions, on top of the battery charger while it is charging. Heat will build up and could result in a fire.
- Do not charge batteries other than Battery Pack NB-4L in this charger.
- The battery pack continues to discharge a minimal portion of its power while installed in the camera, even with the power off, or in the charger. This will shorten battery life.
- Do not allow any metal objects such as key rings to touch the - and + terminals (Fig. A), as this can damage the battery pack. To carry the battery pack or store it during periods of disuse, always replace the terminal cover (Fig. B).
- Even charged battery packs continue to discharge naturally. You are advised to charge the battery on the day of use, or one day before, to ensure a full charge.
- Since storing a fully charged battery pack for long periods of time (about one year) may shorten its life cycle or affect its performance, 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 to 30o C (32 to 86o F). If you do not use the battery pack for long periods of time, charge it fully and discharge it fully in the camera about once a year before returning it to storage.
- If the performance of the battery pack diminishes substantially even when it is fully charged, its life has been exceeded and it should be replaced.
