  • Claims of fast charging a Li-ion Acer travelmate 291 laptop battery pack in one hour or less usually results in lower charge levels.
    Such a charger simply eliminates stage two and goes directly into 'ready' once the voltage threshold is reached at
    the end of stage one. The charge level at this point is about 70%. The topping charge typically takes twice as long
    as the initial charge.
    Depending on the charger and the self discharge of the Acer travelmate 291 battery, a topping charge may be implemented once
    every 500 hours or 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05 volts per cell
    and turns off when it reaches 4.20V/cell.
    No trickle charge is applied because the Li-ion laptop battery pack for Acer travelmate 291 laptop is unable to absorb overcharge.
    Trickle charge could cause plating of metallic lithium, a condition makes the cell unstable. Instead, a brief topping
    charge is applied to compensate for small amount of self-discharge Acer travelmate 291 battery and its protective circuit consume.

    Upgrade my Acer laptop battery from Ni-MH to Li-ion

    Ni-Cd, Ni-MH and Li-ion Acer notebook battery are all fundamentally different from one another and cannot be substituted unless the Laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry.
    Please refer to your manual to find out which rechargeable battery types the Laptop device supports or use our Acer battery Finder above to find all the compatible Laptop Battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run times.

    For example, if your Laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion Laptop Battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.

    Example:

    Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
    Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
    The Li-ion is stronger and has longer run time.

    How can I maximize the performance of my Acer laptop battery?

    There are several steps you can take to help you get maximum performance from your Laptop Batteries:

    Prevent the Memory Effect - Keep the battery healthy by fully charging and then fully discharging it at least once every two
    to three weeks. Exceptions to the rule are Li-ion batteries which do not suffer from the memory effect.

    Keep the Acer laptop battery pack clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol.
    This helps maintain a good connection between the battery and portable device.

    Exercise the battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a Laptop Battery has not been used for a long period of time, perform the new battery break in procedure described above.

    Battery Storage - If you don't plan on using the Laptop Battery for a month or more, store it in a clean, dry, cool place
    away from heat and metal objects. Ni-Cd, Ni-MH and Li-ion batteries will self-discharge during storage; remember to
    recharge the batteries before use.

    What is the run time of batteries-company.com's Laptop Battery?

    Acer laptop battery have two main ratings on them: Volts and Amperes. Because size and weight of Laptop Battery is
    limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most
    Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by
    multiplying the Volts and the Amperes together. For example:

    14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).

    14.4 x 4.0 = 57.60 Watt-Hours

    Watt-Hours signifies the energy needed to power one watt for one hour. This Acer laptop battery can power 57.60 watts
    for one hour. If your Laptop runs at 20.50 watts, this Laptop Battery could power your Laptop for 2.8 hours.
