2. Safety Information and Warnings
Failure to follow these safety instructions may result in fire, electric shock, injury, or damage to the battery and connected devices.
- Polarity Check: Before connecting, always verify the battery's positive (+) and negative (-) polarity against your device's requirements. The red wire is positive (+), and the black wire is negative (-). Incorrect polarity will damage your equipment.
- Connector Compatibility: Ensure the JST PH2.0mm connector matches your device. If the connector does not match, you may need to replace it, paying strict attention to polarity during soldering.
- Avoid Short Circuits: Never allow the red and black wires to touch each other. This will cause a short circuit and can lead to fire or explosion.
- Non-Power Battery: This Lithium Polymer battery is designed for general electronic applications and is NOT a high-power battery. It is unsuitable for devices requiring high current, such as UAVs, model aircraft, electric toys, or power tools.
- Charging: Use only compatible chargers designed for Lithium Polymer batteries. Adhere to the specified charging voltage (4.25V maximum) and temperature range (0°C to 45°C).
- Storage: Do not leave the battery discharged for extended periods. Charge it regularly to maintain its health and capacity. Store in a cool, dry place.
- Physical Damage: Do not puncture, crush, or expose the battery to extreme temperatures or direct sunlight. Discontinue use if the battery shows signs of swelling, leakage, or damage.
- Disposal: Dispose of batteries according to local regulations. Do not dispose of in general waste.
