Lithium Battery Usage Guidelines

1. Always use a standard lithium battery charger (4.2V) for charging.

2. Avoid high-current discharge (protected by the built-in protection circuit).

3. Prevent over-discharge. The voltage of a single cell should not drop below 2.5V (protected by the built-in protection circuit).

4. Never disassemble or short-circuit the battery, as this may cause short-circuiting and fire.

5. Operating temperature range: -20°C to 60°C.

Charging Instructions

• Charging voltage limit: 4.25±0.05V

• Cut-off voltage: 2.75V

• Standard charging current: 0.5C

• Maximum charging current: 1C

• Standard discharge current: 0.2C

• Maximum continuous discharge current: 2C

For optimal battery lifespan and performance, complete full charge-discharge cycles during use. Do not disconnect the battery during charging. If storing the battery long-term, fully charge it, ensure it is insulated, and recharge periodically.

Precautions

1. Over-discharge is strictly prohibited for rechargeable batteries.

2. For unprotected batteries (without a protection board), immediately charge if voltage drops below 2.75V. Do not continue use (to prevent over-discharge).

3. For unprotected batteries, remove them once fully charged to avoid overcharging.

4. Always use a certified charger for charging.
