6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your SMALLRIG VB99 SE battery.
- Storage: Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, ensure the battery is charged to approximately 50-60% capacity.
- Cleaning: Use a soft, dry cloth to clean the battery's exterior. Avoid using harsh chemicals or abrasive materials. Keep the ports free from dust and debris using the provided silicone cover.
- Charging Cycles: While modern lithium-ion batteries do not suffer from a 'memory effect', it is generally good practice to fully discharge and recharge the battery periodically (e.g., every few months) to recalibrate the battery management system.
- Avoid Physical Damage: Protect the battery from drops, impacts, and excessive pressure, which can damage internal components.
7. Troubleshooting
If you encounter issues with your SMALLRIG VB99 SE battery, consider the following:
- Battery Not Charging: Ensure the USB-C cable and charger are functioning correctly and meet the 65W PD 3.0 specification. Check the OLED screen for charging indicators.
- Device Not Powering On: Verify that the battery has sufficient charge. Ensure the correct port is used for the device and the cable is securely connected. Check the device's power requirements against the battery's output capabilities.
- Intermittent Power Supply (with multiple devices): If powering multiple high-wattage devices simultaneously, the total power draw might exceed the battery's maximum output (100W total). This can cause the battery to temporarily stop supplying power to protect itself. Reduce the number of connected devices or use devices with lower power consumption.
- OLED Screen Not Responding: Try a short press of the power button. If unresponsive, the battery might be fully discharged or require a reset (if applicable, refer to specific reset procedures or contact support).
- Overheating: If the battery feels excessively hot, disconnect all devices and allow it to cool down in a well-ventilated area. Overheating can trigger safety mechanisms and temporarily shut down the battery.
