How to read the battery specification

In order to find a correct laptop battery for your computer there are some technical terms you need to understand.

There are two important figures to consider in reading and understanding a battery pack’s specifications. First is the voltage of the battery pack in terms of Volt or V. Second is the capacity rating in terms of Ampere-hours (Ah) or milliamp-hours (mAh: 1mAh=0.001Ah). The voltage of the new battery pack should always match the voltage of the original battery. The higher the Ah or mAh capacity rating of the battery pack means the longer runtime and does not mean incompatibilities. Most of our battery packs have higher Ah or mAh readings than the original, yet are manufactured up to original equipment manufacturer (OEM) standards.

The Chemistry type of the battery package is important too. The most common types of chemical used in notebook battery are Li-ion and NiMH. Make sure the chemistry type is supported by your laptop computer.
