Notes on using the battery pack

• Be sure to use only genuine Sony brand battery packs.
• The correct remaining battery indicator may not be displayed under some operating or environmental conditions.
• Do not expose the battery pack to water. The battery pack is not water-resistant.
• Do not leave the battery pack in extremely hot places, such as in a car or under direct sunlight.

Notes on charging the battery pack

• Charge the battery pack (supplied) before using the product for the first time.
• The charged battery pack will discharge little by little even if you do not use it. Charge the battery pack each time before you use the product so that you do not miss any opportunities to shoot images.
• Do not charge battery packs except battery packs specified for this product. Doing so can result in leaks, overheating, explosions, electric shocks, burns, or injuries.
• When you use a completely new battery pack or a battery pack that has not been used for a long time, the charge lamp (CHARGE) may flash quickly when the battery is charged. If this happens, remove the battery pack and then re-insert it to recharge.
• We recommend charging the battery pack in an ambient temperature of between 10 °C and 30 °C (50 °F and 86 °F). The battery pack may not be correctly charged in temperatures outside this range.
• Operation cannot be guaranteed with all external power supplies.
• After charging is finished, disconnect the charger from the wall outlet (wall socket) if charging with a charger, or disconnect the USB cable from the camera if charging the battery pack while it is inserted into the camera. Not doing so may result in a shorter battery life.
• Do not continuously or repeatedly charge the battery pack without using it if it is already fully charged or close to fully charged. Doing so may cause a deterioration in battery performance.
• If the product's charge lamp flashes while charging, remove the battery pack being charged, and then insert the same battery pack firmly back into the product. If the charge lamp flashes again, this may indicate a faulty battery or that a battery pack other than the specified type has been inserted. Check that the battery pack is the specified type.
  If the battery pack is the specified type, remove the battery pack, replace it with a new or different one and check that the newly inserted battery is charging correctly. If the newly inserted battery is charging correctly, the previously inserted battery may be faulty.
• If the charge lamp flashes while charging the battery pack inside the camera, this indicates that charging has stopped temporarily and is on standby. Charging stops and enters standby status automatically when the temperature is outside of the recommended operating temperature. When the temperature returns to the appropriate range, charging resumes and the charge lamp lights up again.

Remaining battery indicator

• The remaining battery indicator appears on the screen. It takes about one minute for the correct remaining battery indicator to appear.
• The correct remaining battery indicator may not be displayed under some operating or environmental conditions.
• If the remaining battery indicator does not appear on the screen, press the DISP (Display Setting) button to display it.

Effective use of the battery pack

• Battery performance decreases in low temperature environments. So in cold places, the operational time of the battery pack is shorter. To ensure longer battery pack use, we recommend putting the battery pack in your pocket close to your body to warm it up, and insert it in the product immediately before you start shooting. If there are any metal objects such as keys in your pocket, be careful of causing a short-circuit.
• The battery pack will run down quickly if you use the flash or continuous shooting function frequently, turn the power on/off frequently, or set the monitor very bright.
• We recommend preparing spare battery packs and taking trial shots before taking the actual shots.
• If the battery terminal is dirty, you may not be able to turn on the product or the battery pack may not be properly charged. In that case, clean the battery by lightly wiping off any dust using a soft cloth or a cotton swab.

How to store the battery pack

To maintain the battery pack’s function, charge the battery pack and then fully discharge it in the camera at least once a year before storing it. Store the battery in a cool, dry place after removing it from the camera.

On battery life

• The battery life is limited. If you use the same battery repeatedly, or use the same battery for a long period, the battery capacity decreases gradually. If the available time of the battery is shortened significantly, it is probably time to replace the battery pack with a new one.
• The battery life varies according to how the battery pack is stored and the operating conditions and environment in which each battery pack is used.
