Laptop Battery Guide

The best part of having a laptop is the mobility, which of course requires battery power. There used to be different battery types used for laptops but these days laptops come with a Lithium Ion battery. (also known as Li Ion or LiON)
Unfortunately there is a stigma surrounding rechargeable batteries which do not apply to Lithium Ion, most notably concerning the "memory effect". The memory effect is now widely used to explain why any battery doesn't deliver its full capacity, to counter this people have charged their batteries in certain ways to avoid or try to fix it.
Lithium Ion batteries do not suffer from "memory effect", a poor performing laptop battery may be caused by damage or age which means time for a new one. (doh!)
Some would have you believe you need to fully discharge a laptop battery before you recharge it, which you should NOT do. Lithium Ion laptop batteries have a limited amount of charge cycles(cycle = fully discharged and then fully charged) so if you fully discharge your battery every time before charging then you greatly shorten the life of the pack.
Fully discharging a battery through actual use of the laptop is not a problem because you're actually using the power. Discharging fully just for the sake of keeping your lithium ion battery "healthy" is detrimental.

Does "limited charge cycles" have you worrying about replacing batteries often? Lithium Ion batteries have anywhere from 300-600 charge cycles which is 2-4 years of use for the average user.
To get maximum use out of your lithium ion laptop battery there are a few things to keep in mind.
You should consider buying a spare pack only if you find yourself running out of battery power often, don't buy one to have "just in case". Lithium Ion packs start to age as soon as they're produced and can irreversibly lose around 20% capacity per year even when unused. (note storage tip above to minimize this)
