    when connected to power supply and using it (gaming, working, etc..), not charging it obviously, is it ok to leave the battery on? is alienware's battery "smart" if i may call it like that.. or i need to take it off

    i'm asking this as i broked my ex laptop's battery by keeping it inside and it broked pretty fast, now it only lasts about 5 minutes top

    i hope you understand what i'm referring to, sorry if i am unclear, as i must practice my english more

    Leaving a battery in a system while using the system will not hurt the battery. The new Lithium ion batterys do not have the memory problems that older battery's have.

    I had similar questions as I wanted the battery to have as long of a lifetime as possible. Here is what I found online.

    Simple Guidelines


    Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.


    Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.


    Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.


    Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)


    Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.


    If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.
