zDo not allow any metal objects such as key rings to touch the and terminals (Fig. A), as this can damage the battery pack.

zEven 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.

zSince 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 30 °C (32 to 86 °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.

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