6. Safety Information
Observe the following safety precautions to prevent damage to the product or injury:
- Use Only Specified Charger: Charge batteries only with the BM Premium Dual Bay USB Digital Charger provided or a compatible charger designed for LI-90B/LI-92B batteries.
- Avoid Short Circuits: Do not short circuit battery terminals.
- Do Not Dispose in Fire: Batteries may explode if disposed of in fire.
- Temperature: Do not expose batteries or charger to high temperatures.
- Circuit Protection: The charger is built with multiple circuit protections including over-charging, short-circuit, high-temperature, and surge protection.
- Memory Effect: The Li-ion batteries are memory-free, allowing you to charge them at any time without reducing performance.
- Storage: Store batteries in a cool, dry place when not in use.
- Disposal: Dispose of used batteries according to local regulations.
7. Troubleshooting
- Charger Not Working / Indicator Lights Flashing Red:
This often indicates insufficient power input. Ensure your USB power source (wall adapter, car charger, power bank) provides a minimum of 2.1A at 5VDC. Standard computer USB ports or older phone chargers may not supply enough current.
- Batteries Not Charging:
Verify that batteries are inserted correctly with contacts aligned. Check the power source as described above. If the issue persists, try charging one battery at a time to isolate the problem.
- Short Battery Life:
Ensure batteries are fully charged before use (LED turns green). Battery performance can degrade over time with repeated charge cycles. Extreme temperatures can also affect battery life.
8. Maintenance
- Keep the charger and batteries clean and dry.
- Avoid dropping or subjecting the charger and batteries to strong impacts.
- Do not attempt to disassemble the charger or batteries.
