3.2 Installation Steps (General Guidance):
- Power Off Device: Ensure your Zeblaze Thor 5 smartwatch is completely powered off before beginning.
- Disassembly: Carefully open the smartwatch casing using the provided tools. Refer to specific disassembly guides for the Zeblaze Thor 5 model if available, as procedures can vary.
- Disconnect Old Battery: Gently disconnect the old battery connector from the smartwatch's mainboard. Avoid pulling on the wires.
- Remove Old Battery: Carefully remove the old battery. It may be secured with adhesive.
- Install New Battery: Place the new replacement battery into position and connect its connector to the mainboard.
- Reassembly: Carefully reassemble the smartwatch casing, ensuring all components are properly seated and secured.
3.3 Initial Battery Activation:
After replacing the battery, follow these steps to activate its properties for optimal performance:
- Full Discharge: Use the smartwatch until the battery is completely depleted and the device powers off.
- First Charge: Connect the smartwatch to its original charger and charge it continuously for 8 hours, even if the device indicates a full charge sooner.
- Cycle Repetition: Repeat the full discharge and 8-hour charge cycle 3-5 times. This process helps to calibrate the new battery and achieve its best use effect.
4. Operating Guidelines
Proper charging practices are crucial for the longevity and safety of your battery.
- Use Original Charger: Always use the original charger and data cable provided with your Zeblaze Thor 5 smartwatch. Using inferior or incompatible chargers can damage the battery and compromise safety.
- Optimal Charging Range: For best battery health, it is recommended to keep the battery level within the range of 20% to 80%. Avoid consistently depleting the battery to 0% or charging it to 100% for extended periods.
- Avoid Simultaneous Use: Do not use your smartwatch or other devices while charging. This can lead to increased heat, reduced battery life, and potential safety risks.
- Automatic Cut-off: The battery features intelligent fast charging technology that automatically cuts off power when fully charged to prevent overcharging and swelling.
5. Maintenance and Battery Life Extension
Follow these suggestions to maximize the lifespan and performance of your battery:
- Prevent Over-Discharge: Do not allow the battery to over-discharge or remain idle for long periods at very low charge levels, as this can lead to expansion.
- Regular Charging: If the battery level drops below 20%, charge it promptly. Avoid keeping the battery in a low state for extended durations.
- Temperature Control: Avoid exposing the battery to extremely low temperatures, as this can cause battery swelling or damage.
- Charger Quality: Only use high-quality, compatible chargers. Inferior chargers can harm the battery.
- Remove from Charger: Do not leave the battery connected to the charger for excessively long periods after it has reached full charge.
- No Disassembly: Do not attempt to disassemble or modify the battery structure.
- Maintain Label Integrity: Do not tear off the battery label, as it contains important safety and product information.
6. Safety Information and Warnings
Your battery is equipped with multiple safety features, but adherence to these warnings is crucial for preventing hazards:
- Do Not Open/Disassemble: Never attempt to open, disassemble, or service the battery yourself. This can lead to short circuits, fire, or explosion.
- Temperature Exposure: Do not expose the battery to temperatures above 60℃ (140℉). High temperatures can cause the battery to swell, leak, or explode.
- Disposal: Recycle or dispose of the battery properly according to local regulations. Do not dispose of it in household waste or by incineration.
- Impact: Avoid dropping or subjecting the battery to severe impacts.
- Puncture: Do not puncture the battery with any sharp objects.
