How can I maximize the discharge time of the IBM laptop battery?

The discharge time will vary by user. It depends on the features you are using in your notebook PC during the time you are using the battery. For example, if you are playing a movie from DVD and you are connected to a wireless network, your battery life will be shorter than normal. If you are just reading or editing a file or answering email on a wired network connection, you will experience maximum battery life. Please note that your maximum discharge time will shorten as the storage capacity decays.

Tips for maximizing discharge time:
1.Lower the brightness on the display.
2.Check the Power Management settings are set to "Max Acer Battery".
3.Remove the battery from the notebook PC when it is not being used or charged for a long period
4.Purchase another battery to extend the overall operating time on battery.
5.Store the battery in a cool dry location.

Will the battery performance degrade over time?
The storage capacity of a notebook PC will degrade over time based upon notebook usage. Degradation is a normal condition of all rechargeable Acer battery and is not limited to notebook PCs or other products. If the notebook is used on battery power often, requiring one or more recharges per day, the battery will experience a high degree of degradation and will need to be replaced sooner than a battery that is used occasionally. Also, temperature and humidity impact the storage capacity of a battery for Acer laptop . It is best to store the battery and notebook in a cool dry place.

Under normal operating conditions, a battery should perform well for over a year, but it will hold less of a charge every time it is recharged. The Battery Check utility validates that every battery is operating normally by checking the condition of the cells of the Acer laptop battery. The Health status will change to " Replace " if the cells are not functioning normally.

NOTE: As with all IBM laptop battery, the maximum capacity of this battery will decrease with time or use. Loss of battery capacity will vary depending on the product configuration and usage, including but not limited to: product model, applications running, power management settings, and product features. The battery warranty does not cover natural deterioration of battery capacity. Your battery is only warranted from defects in materials or workmanship resulting in failure, to determine if your battery has had a warranted failure you may be required to run an HP diagnostic.
