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
-
Full performance and longevity is only achieved after 2 to 3 complete charge and discharge cycles
-
If the battery will not be used for a long time, please put it in a dry and cool place and fully charge it every three months
-
After you go through 2 to 3 cycles, you'll never have to condition your battery again!
Proper Charging Habits:
-
Use the original charger that came with your device for best performance
-
To prolong battery lifespan, charge when the level drops to 20-30% rather than letting it drain completely to 0%
Storage Guidelines:
-
Store at approximately 25-50% charge in a cool, dry place
-
Capacity loss is minimal under proper storage conditions
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. Note: In the interim before you get it fixed, do not charge the phone or use it . 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.
