• Cleaning: Keep battery terminals clean and dry. Use a clean, dry cloth to wipe off any dust or debris.
• Disposal: Do not dispose of batteries in household waste. Follow local regulations for proper recycling of lithium-ion batteries.

Safety Warnings:

• May leak, flame, or explode if misused.
• Do not disassemble, short circuit, or expose to high temperatures.
• Keep out of reach of children.
• Do not mix with other battery types or brands.
• If the battery shows signs of damage, swelling, or leakage, discontinue use immediately and dispose of it properly.

5. Troubleshooting

If you encounter issues with your EEMB 9V batteries, consider the following:

Battery not charging:

• Ensure the USB cable is securely connected to both the battery and the power source.
• Try a different USB cable or power source to rule out cable/charger issues.
• Check if the charging indicator light (if present) is active.

Device not powering on or battery life is short:

• Verify that the battery is fully charged.
• Check the battery polarity when inserted into the device.
• Ensure the device itself is functioning correctly with other known good batteries.
• For short battery life, consider the power consumption of the device; some high-drain devices may deplete batteries faster.

Battery feels hot during charging or use:

• A slight warmth is normal, but excessive heat indicates a potential problem. Discontinue use and charging immediately.
• Ensure the battery is not short-circuited or damaged.
