Using an External Charger (Recommended)
- Remove the NP-BX1/M8 battery from your camera.
- Insert the battery into a compatible Sony external charger (e.g., Sony BC-TRX, ACC-TRDCX) or a reputable third-party charger.
- Connect the charger to a power source (wall outlet or USB power bank).
- Monitor the charging indicator lights on the charger. Lights typically change color (e.g., red to green) or display progress to indicate charging status.
- Once fully charged, remove the battery from the charger.

In-Camera Charging (Alternative)
If an external charger is not available, you can charge the battery while it is inside the camera:
- Ensure the battery is correctly inserted into the camera.
- Connect the camera to a power source using a compatible USB cable (usually Micro-USB for older models or USB-C for newer models) and a USB AC adapter.
- The camera's indicator light will show charging status.
5. Usage Tips
- Carry Spares: For extended shooting sessions or travel, it is advisable to carry at least two to three fully charged spare batteries.
- Optimal Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Use a protective case to prevent short circuits.
- Avoid Full Discharge: While Lithium-Ion batteries do not suffer from memory effect, avoiding complete discharge can prolong their overall lifespan.
- Temperature Considerations: Battery performance can be affected by extreme cold. Keep batteries warm in cold environments to maximize usage.
