    Use of the battery in a laptop?

    Hi,

    To keep the battery for a longer life what is the best:

    1. using the mainpower : removing the battery and performing regularly a
    decharging and recharging?
    2. using the mainpower : keeping the battery into the PC and performing
    regularly a decharging and recharging?
    3. only working with the battery and of course performing the charging when
    needed?

    This depends on the battery technology used in the device. Most newer
    batteries are Lithium-Ion type batteries which don't suffer from normal
    "memory" issues but do lose capacity if overheated or charged at too high a
    voltage. I personally would check the owner's manual that came with the
    device as most do have usage/charging advice.

    Re: Use of the battery in a laptop?

    Hi,
    Thanks for the reply.
    I am using a Li-Ion battery (HP-laptop) and the documentation says
    decharging and recharging regularly but this is not for a longer live of the
    battery but only for a correcter indication of status of the battery on the
    PC.
    I did use the battery constantly in together with the mainpower bur after
    1,5 year i can only 1 minutes on the battery alone.
    From their my question what is the best general use of a battery in a
    laptop.

    Can overheating take place when battery is in the PC and mainpower
    constantly used?
    Charged to high is suppose will be under control?

    Regards
    Huib

    LI batteries are better in most ways than the Ni Cad batteries.
    However-- discharging beyond about 80% can reduce capacity, or "kill" the
    battery.
    Overcharging or too rapid discharge can damage the battery, or even cause a
    fire. Some batteries have circuitry inside the battery case that is intended
    to reduce the chances of overcharging, over discharging and high discharge
    rates or % of capacity.
    Full capacity "may" be regained by going through a charge/discharge cycle,
    usually thought to be 3 to 5 cycles.
    Apple currently has a bit of a problem with iPods and the LI batteries.
    (~800 documented problems/complaints, at least that's what the Feds seem to
    be saying)
    I really hope that the "A123" type makes it into laptop use. Currently, it
    seems to be going into power tools, and under priority development for
    electric vehicles.

    The real problem with laptops and batteries boils down to an unrealistic use
    time rating.
    If this isn't bad enough, part of the charge circuitry is in the battery,
    and the rest in the laptop.
    This supposedly allow the battery mfr greater control of the
    charge/discharge process.
    However, the battery mfr also has a vested interest in supplying replacement
    batteries.

    I use LI Po batteries for RC electric powered aircraft, and have a fairly
    complex and programmable battery charger/balancer/cycler.
    (Ni Cad, Li, Li-Po, Lead Acid, and A123 batteries.)
    I recently used this unit to recover a laptop battery that was unchargable
    using an Acer "netbook". Seems the problem is known, and peculiar to one
    battery maker.
    The netbook battery was usable after recovery, but had a reduced capacity.
    Since it was under warrenty, it was replaced.

    Re: Use of the battery in a laptop?

    Hi, Roger & Chuck
    Thanks both for the technical details and the clear information.

    I can indicate in my Vista (HP DV9285ea) when an indication is required at a
    certain level but i have no means to controle the charging level.
    So in my case is the best to remove the battery (only working on the
    mainpower and regular e.g. once / per month checking of the charging level
    is between 40% - 80%.

    Sorry Roger to mention it also into the other forum, but battery is HW and
    not Vista related so i played on two horses ...but you are wright.

    Regards
    Huib

    I have a 4-year-old Dell laptop that still works with its original
    battery pack. Other than removing the battery when I don't plan on using
    the unit for a month or two, I have not paid much attention to the
    charge/discharge status of the battery.

    Obviously the battery is shot if you only get a minute's use out of it.
    How old is this laptop?

    Hi,
    Only 2 years, i am daily using my PC using the mainpower with the battery
    always 100% loaded.
    I recently dedected the problem after i forgot to connect the mainpower and
    the battery when already after 1 minute to 10%.
    I am intended to bye a new battery but i want first to some technical
    details which i did receive on the forum with thanks to all.
    regards
    Huib

    When I purchased a new battery for an old Dell Inspiron 5150 the
    instructions stated to only charge the battery when it was almost dead and
    to charge it till it's fully charged. Also, if you use your laptop mostly on
    AC power, to take the battery out. This isn't an observation from me. It's
    directly from the battery manufacturer. Some batteries can be revived using
    this procedure. Run it till it's dead, then give it a full charge. This
    may have to be done multiple times. In your case, though, "it's dead, Jim!"

    For best battery life, leave it out of the laptop 40% charged and only
    charge it when you need to use it.

    Unfortunately for most of us, that's an inconvenient way to work and
    if there's a power failure you crash.

    Thanks , Michael i wil give it a try...
    Also thanks to Bob indeed meanwhile i learned indeed that it is best leaving
    it out of the PC but than the security.
    If charging / decharging doesn't help i think i will keep the pld one into
    the PC and handle with care the new one on a storage place to use it when no
    AC power is available.
