Important Battery Information

First-Time Use and Conditioning:

New Lithium-Ion batteries require proper conditioning to achieve optimal performance:

• New Lithium Ion batteries must be FULLY CHARGED and FULLY DISCHARGED 2 to 3 times before being FULLY CONDITIONED 

• When you use the battery for the first time, it will first consume the virtual energy that comes with the battery when it comes out of the factory 

• After it discharges, charge it for 6-8 minutes, being careful not to overcharge so as not to damage the battery cells and affect the service life 

• Fully activate the battery after 3-4 cycles to achieve the best possible effect 

• Please remember that a new Lithium-Ion battery's full performance and longevity is only achieved after 2 to 3 complete charge and discharge cycles 

• After you go through 2 to 3 cycles, you'll never have to condition your battery again! 

Installation Requirements:

• Professional installation is recommended 

• Instruction not included. If you need to install by yourself, you can watch some installation videos on YouTube 

• These videos can help you better complete the installation 

Proper Charging Habits:

• Use the original charger that came with your device for best performance 

• It is compulsory that after receiving the battery, put it into your phone and plug into charge for 3-5 hours continuous charge in switch off mode for first time—not less than and not more than that 

• To prolong battery lifespan, charge when the level drops to 20-30% rather than letting it drain completely to 0%

Warranty Information:

• Some premium batteries come with up to 3 months warranty 

• Warranty covers manufacturing defects only 

• Note that swollen and burnt batteries are typically not covered under warranty 

Swollen Battery Warning:

If your old battery is swollen, handle with extreme caution. Do not puncture, crush, or apply heat—this can cause fire or explosion. Properly dispose of swollen batteries at authorised recycling centres.

Proper Disposal:

Never throw lithium-ion batteries in household trash. Always recycle through authorised electronic waste recycling centres. Tape over the terminals before disposal to prevent short circuits.

Installation Tips

• Before installation, carefully inspect the items for any visible damage and test functionality

• Make sure that the connector is properly connected to your device during installation

• Check if there is any dust in the connector or if any pin is broken

• Clean the connector using IPA or swabs if necessary
