The average laptop user needs to use his machine unplugged on a regular basis. Programs are becoming increasingly resource heavy and therefore drain battery life faster. Upgrading a laptop's battery is a matter of availability. If there is no improved and compatible battery manufactured for your laptop's model, you're out of luck.
Number of Cells
Nine-cell batteries are bulkier than six-cell batteries, but obviously have a higher charge potential. A person looking to upgrade his battery should identify the number of cells the current battery has. The most common setups use four- and six-cell batteries. Consumer laptop batteries can have up to 16 cells.
All recently manufactured batteries are composed of lithium ion cells. The old standard was nickel, but any upgrade from such a battery is investing in a new system. Therefore, it is more important to look at the number of cells and milliamp-hour (mAH) rating.
Milliamp-hour (mAH) Rating
A laptop battery with a higher mAH rating denotes one with a larger energy storage capacity. Aftermarket and non-original manufacturer batteries often provide compatible batteries that have higher mAH ratings than original batteries.
Buying an Upgrade/Replacement
The most affordable route in finding an upgrade is through a non-original manufacturer merchant. Non OEM batteries are similar in quality to OEM batteries. They are also easier to order and less expensive. They generally come with one -ear manufacturer guarantees.
Installing a New Battery
Installing a replacement battery is as simple as removing the old one and inserting the new. However, new batteries have certain procedures to follow. See the reference "Laptop Battery Tips" below.
