Suggestion
1.For use a new battery, you'd better try a few cycles of discharging to 5%, then charging up to 95%.
2.Do not always run out of a battery to 0%, this would make it damage or usage life shortened.
3.Do not put away a battery for a long time (more than 2 months), this would cause cells inside of a battery losing balance.
The battery will not be charged up again or its lasting time shortens, so do charge a battery at least one time within two months.
4.Do not disassemble, crush or puncture; Do not dispose of in fire or water.
5.Choose correct laptop adapter, if a replacement battery is not charged, perhaps your adapter can not be compatible with it.
