Hello everyone.This is my first post.I want to thank you in advance for reading it. I have a Dell Inspiron 1100 laptop that needa a new battery. My current battery has a 4300mAH number that, I think, refers to the number of cells it has, and thus, the amount of holding (charge) capacity. Can I get the same battery but with a 7300mAH instead? Will it be compatible with my laptop? I appreciate any help I can get; I am looking to purchase a new battery right away.
Thank you all..............

I think, refers to the number of cells

mAH = milliampere-hour

The commonly seen milliampere-hour (mAh or mAh) is one-thousandth of an ampere-hour (i.e., 3.6 coulombs), and is a technical term for how much electrical charge a particular battery will hold. Small batteries, such as those in laptops and digital cameras, are often rated in milliampere-hours. As an example, digital camera batteries with higher mAh values theoretically last longer without requiring a recharge, allowing one to take more photographs before having to replace the batteries.
