121nN Precautions > Using the Battery Pack Using the Battery Pack ❑Battery life is shorter in a cold environment. This is due to decreased battery efficiency at low temperatures. ❑Charge battery packs at temperatures between 10°C to 30°C. Lower temperatures require longer charging time. ❑Do not charge the battery pack in any way other than as described in this user guide or as designated by Sony in writing. ❑While the battery pack is in use or being charged, heat builds up in the battery pack. This is normal and is not cause for concern. ❑You do not need to discharge the battery pack before recharging. ❑If the battery pack quickly runs out of power after being fully charged, it may be reaching the end of its life and should be replaced.
