Cheap Laptop Batteries

An important factor to consider is how much battery life you’ll need on your laptop. No matter how much cheap laptop batteries have, using your built-in DVD drive a lot and having a 17″ screen will drain it faster. Battery technology–just like any technology–is improving all the time. It doesn't matter if you bought a Dell, Sony, Apple, Toshiba, Gateway, or a Sanyo computer, at some point your cheap laptop batteries pack is going to get old and not hold a solid charge anymore. Before you decide you need to buy a new battery for your notebook you might try running your battery all the way down (to the point that the computer won't even turn on) and then try to give it a full charge.
When selecting cheap laptop batteries, manufacturers will often list an amount of “cells,” where each cell has a certain capacity; thus a 9 cell has 50% more capacity than an equal model 6-cell battery. That is useful for comparing directly, but the story is more complex if you wanted to compare different batteries on different laptops. Batteries have a voltage rating (V) and milli-Amp hours (mAH), which, if multiplied together, give you milliwatt hours. For example, 14.8 V cheap laptop batteries with 4460 mAH gives you 66,000 milliwatt hours (66 watt-hours). You can compare batteries this way, but also keep in mind that different cheap laptop batteries have very different power requirements that vary based on the components and how well the operating system manages power consumption. Typically, bigger, heavier batteries will give you a higher watt-hour rating. A 6-cell battery may be the same form factor as a 9-cell, but the 6-cell will weigh less since there’s less chemical in it to hold onto that charge.
