Compaq Laptop Batteries

Founded in 1982, Compaq's name is a portmanteau of the words ‘compatibility and quality.’ Historically, the Compaq Portable was one of the earliest laptop computers that was IBM-compatible. Compaq merged with Hewlett-Packard in 2002, with Compaq laptop batteries and laptops now marketed as a brand name under the HP company.

Compaq Laptop Models

A number of Compaq laptop models and corresponding laptop batteries are currently on the market, including the 300, 400, 500 and 600 series; Compaq Presario; the Compaq NX series; Compaq tablets; Compaq Armada; Compaq 2210b, 2230s, 2510p, 2710p series; and the Compaq Evo laptop series. Compaq laptop batteries vary between different laptop models, making it essential to be clear about the specific model of Compaq laptop you have before you choose Compaq laptop batteries.

Types of Compaq Laptop Batteries

Compaq laptop batteries tend to look very similar from the outside, but inside they can vary quite considerably. With the most common being 6-cell Compaq laptop batteries and 8-cell Compaq laptop batteries, Compaq laptop batteries are also available in 12-cell and higher. It is a common misunderstanding that laptop batteries are made from a single cell, presumably because the battery looks solid from the outside. This is not the case, with the various cell arranged in a specific order inside the metal casing to provide optimal performance.

Compaq's Lithium-Ion Batteries

While a variety of cell configuration are available, the majority of Compaq laptop batteries are 6 cell lithium-ion. With an optimal power-to-weight ratio, lithium-ion batteries are a common choice for laptop manufacturers as they are high powered without being needlessly heavy. One of the most important advantages of lithium-ion batteries is that they do not suffer from the ‘memory effect’ that some other types of batteries do. The ‘memory effect’ refers to a defect in earlier battery technology that required batteries to be fully charged and completely discharged at least once a month, otherwise the battery would lose some of its power capacity and battery life. Compaq laptop batteries are lithium-ion batteries and do not suffer from the memory effect, although it is always good practice to fully discharge and then completely recharge your laptop battery for optimal battery performance.
