Important Battery Information

First-Time Use:
For optimal performance, condition your new battery properly :

• New Lithium Ion batteries achieve full performance and longevity after 2 to 3 complete charge and discharge cycles

• After these initial cycles, the battery will be fully conditioned and ready for normal use

• For optimal performance, calibrate your newly installed battery after completing the installation

Battery Calibration:
For the phone's software to accurately read the new battery's capacity, follow this procedure:

1. After installation, charge the battery to 100% and continue charging for at least 2 more hours

2. Use the device until it shuts off due to low battery

3. Charge it to 100% uninterrupted

4. This helps the phone's software accurately read the new battery's capacity

Storage and Care:

• Do not expose the battery to flame or excessive heat

• Keep the battery dry and avoid immersion in or exposure to water

• Discontinue use immediately if you notice any change in the battery, such as discoloration or deformation

• To maintain battery health, charge when the level drops to 15-25% rather than letting it drain completely to 0%

Swollen Battery Warning:
If your old battery is swollen, take appropriate safety measures. Handle with extreme caution and avoid applying pressure. Do not puncture, deform, heat, or throw batteries into fire .

Proper Disposal:
Lithium-Ion batteries should never be incinerated or thrown into household trash. Always recycle old batteries through authorised electronic waste recycling centres.
