Battery Maintenance Tips

To ensure that your NP-90 battery lasts as long as possible, consider the following maintenance tips:

• Store Properly: If you’re not using your camera for an extended period, store the battery in a cool, dry place where it won’t be exposed to moisture.
• Regularly Inspect: Check the battery for any signs of swelling, leakage, or corrosion, as these can indicate failure.
• Calibrate Periodically: Every few months, allow the battery to fully discharge and then recharge it completely. This process helps maintain its capacity.

Common Issues and Troubleshooting

Despite its reliability, users may encounter some issues with the NP-90 battery. Here are common problems and how to troubleshoot them:

1. The Battery Doesn’t Charge

If your NP-90 isn’t charging, check the charger and its connections. Ensure that you’re using a compatible charger and that the battery contacts are clean.

2. Short Battery Life

If the battery life seems less than advertised, ensure that no power-intensive features are running and consider recalibrating the battery.

3. Overheating

If your battery overheats, stop using it immediately and allow it to cool before attempting to charge or use it again.
