The charging time is approximately 150 minutes using the battery charger (supplied).
The above charging time applies when charging a fully depleted battery pack at a temperature of 25 °C (77 °F). Charging may
take longer depending on conditions of use and circumstances.
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.
