The diffrence 9cell and and 6cell dell xps m1530 battery

Should I buy the 9 cell dell xps m1530 battery ? or buy the 6cell?

The 6 cell dell xps m1530 battery lasts about 2 hours. It comes included in the laptop and fits well. I recommend this because if you get the 9 cell dell xps m1530 battery , with additional charge, it sticks out the back of the laptop so it can’t sit flat.
Someone also said the 9 cell XPS M1530 battery is so hot that eat off the touch pad and where I place my left hand when typing,I

had to return it and buy the 6 Cell,

However, it may be good because it can last up to 5 hours. So, depending on where and how long you use your laptop, both have

their benefits.
