Remove battery when using AC adapter

Would taking out the battery when I am using my laptop while its connected to the AC adapter be wise or not? Would this increase or decrease the life of the battery, or will it not affect anything at all?

 

This is why the battery guide was written.

 

Just read it, thanks. That explains everything

 

in a more simple way, do not remove the battery:

"[edit] Advantages
Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the devices they power.

Li-ion batteries are lighter than other equivalent secondary batteries—often much lighter. The energy is stored in these batteries through the movement of lithium ions. Lithium is the third lightest element, giving a substantial saving in weight compared to batteries using much heavier metals. However, the bulk of the electrodes are effectively "housing" for the ions and add weight, and in addition "dead weight" from the electrolyte, current collectors, casing, electronics and conductivity additives reduce the charge per unit mass to little more than that of other rechargeable batteries. A key advantage of using Li-ion chemistry is the high open circuit voltage that can be obtained in comparison to aqueous batteries (such as lead acid, nickel metal hydride and nickel cadmium). [citation needed]

Li-ion batteries do not suffer from the memory effect. They also have a low self-discharge rate of approximately 5% per month, compared with over 30% per month in nickel metal hydride batteries and 10% per month in nickel cadmium batteries.

According to one manufacturer, Li-ion cells (and, accordingly, "dumb" Li-ion batteries) do not have any self-discharge in the usual meaning of this word.[5] What looks like a self-discharge in these batteries is a permanent loss of capacity, described in more detail below. On the other hand, "smart" Li-ion batteries do self-discharge, due to the small constant drain of the built-in voltage monitoring circuit. This drain is the most important source of self-discharge in these batteries."

"A unique drawback of the Li-ion battery is that its life span is dependent upon aging from time of manufacturing (shelf life) regardless of whether it was charged, and not just on the number of charge/discharge cycles. So an older battery will not last as long as a new battery due solely to its age, unlike other batteries. This drawback is not widely publicised.[6]

At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 degrees Celsius or 77 degrees Fahrenheit will irreversibly lose approximately 20% capacity per year. However, a battery stored inside a poorly ventilated laptop may be subject to a prolonged exposure to much higher temperatures than 25 °C, which will significantly shorten its life. The capacity loss begins from the time the battery was manufactured, and occurs even when the battery is unused. Different storage temperatures produce different loss results: 6% loss at 0 °C(32 °F), 20% at 25 °C(77 °F), and 35% at 40 °C(104 °F). When stored at 40% charge level, these figures are reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively.[7]

Li-ion batteries can even go into a state that is known as deep discharge. At this point, the battery may take a very long time to recharge. For example, a laptop battery that normally charges fully in 3 hours may take up to 42 hours to recharge. Or the deep discharge state may be so severe that the battery will never come back to life. Deep discharging only takes place when products with rechargeable batteries are left unused for extended periods of time (often 2 or more years) or when they are recharged so often that they can no longer hold a charge. This makes Li-ion batteries unsuitable for back-up applications compared to lead-acid batteries, or even to nickel metal hydride batteries.

Because the maximum power that can be continuously drawn from the battery depends on its capacity, in high-powered (relative to C, the battery capacity in A·h) applications, like portable computers and video cameras, rather than showing a gradual shortening of the running time of the equipment, Li-ion batteries may often just abruptly fail.[citation needed]

Low-powered cyclical applications, like mobile phones, can get a much longer lifetime out of a Li-ion battery.[citation needed]

A stand-alone Li-ion cell must never be discharged below a certain voltage to avoid irreversible damage. Therefore all Li-ion battery systems are equipped with a circuit that shuts down the system when the battery is discharged below the predefined threshold.[5] It should thus be impossible to "deep discharge" the battery in a properly designed system during normal use. This is also one of the reasons Li-ion cells are rarely sold as such to consumers, but only as finished batteries designed to fit a particular system.

When the voltage monitoring circuit is built inside the battery (a so-called "smart" battery) rather than the equipment, it continuously draws a small current from the battery even when the battery is not in use; furthermore, the battery must not be stored fully discharged for prolonged periods of time, to avoid damage due to deep discharge.

The g1s battery is away from the heat (GPU and CPU) so do not remove it

 

I think it comes down to personal preference. As the guide says if you want back up power in case of powerloss then leave the battery in. But if Im right then the battery guide and the post above basically says that a li-ion battery will really only last a certain number of cycles.

So in terms of the best method to prolong battery life, take out your battery when using ac power. But make sure its at 40% charge if your storing it.

Leaving your battery in while on ac will cause it to be topped up which will eventually cause wear.

 

I would also say take out the battery. For me I prefer the lesser weight on my lap/stomach while laying down. Prolonging the life of the battery is even better.

Although.. My battery has a year warranty, so it might be nice to wear it out within a year lol!

 

I would always suggest against taking the battery out to conserve it, unless you use it only once in a blue moon (like, 2 months). The advantages of doing so are minimal and far outweighed by the hassle of always taking out and putting in the battery.

If the reason is to keep the notebook light on your belly or something unrelated to battery life, then I have no suggestion, everyone should do what they feel is best for them.
