Setup and Compatibility

Battery Identification

These are 18500 batteries. It is crucial to verify that your device is compatible with 18500 batteries. These batteries are not 18650 batteries and are shorter in length. They cannot be used in devices requiring 18650 batteries due to size differences.

Initial Charging

Before first use, it is recommended to fully charge the batteries using a compatible Li-ion battery charger. Ensure the charger is designed for 3.7V Li-ion cells.

Insertion into Device

Insert the battery into your device according to the polarity markings (+ and -). The button top of the battery typically corresponds to the positive (+) terminal.

Maintenance and Storage

Charging

Always use a dedicated Li-ion battery charger. Avoid overcharging or deep discharging, as this can reduce battery lifespan. Remove batteries from the charger once fully charged.

Storage

For long-term storage, store batteries in a cool, dry place, ideally at around 50% charge. Avoid storing them fully charged or fully discharged. Keep them in a protective case to prevent short circuits.

Disposal

These batteries are rechargeable and designed for multiple uses. When they reach the end of their life, dispose of them responsibly at a local battery recycling facility. Do not dispose of them in household waste.

Troubleshooting

• Battery not charging:
  • Ensure the charger is compatible with Li-ion 18500 batteries and is functioning correctly.
  • Check for proper battery insertion and contact with charger terminals.
  • Inspect the battery for any visible damage.
• Battery not powering device:
  • Verify that the device requires 18500 batteries and not 18650 or other sizes.
  • Check battery polarity in the device.
  • Ensure the battery is sufficiently charged.
  • Test with another known-good battery if available.
• Reduced runtime:
  • Battery capacity naturally degrades over many charge cycles.
  • Ensure the battery is fully charged before use.
  • Extreme temperatures can affect battery performance.
