Can You Upgrade to a More Powerful Laptop Battery?


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.

Battery Composition

  • 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.
