How to find one correct battery for my laptop?

How to find one correct battery for my laptop?

  1. Must match your old battery part number.
  2. Must match your laptop computer model name, the exact model name of your laptop.
  3. Must match your old battery's rating (voltage).
    Please Note:
    1. 7.2V and 7.4V are compatible, they are in common use.
    2. 10.8V and 11.1V are compatible, they are in common use.
    3. 14.8V and 14.4V are compatible, they are in common use.
    ( for example if your old battery's rating is 10.8V, but our is 11.1V, don't worry, our 11.1V battery is compatible with your laptop, it won't damage your laptop. But you can't choose the 7.4V(7.2V) and 14.8V(14.4V) battery, since 7.4V(7.2V) and 14.8V(14.4V) not compatible with 10.8V.)
  4. Don't worry about the difference capacity, high capacity just means the battery can last longer. But please note most high capacity batteries with a bigger size(shape), since them need extra spaces for the battery cells.
    ( for example the 6600mAh,7800mAh,8800mAh batteries are the high capacity batteries,usually they are with bigger shape(size) then the standard batteries. But the high capacity batteries are fit for your laptop,just will extend out(from bottom/side) about 1 inch. )
