9 Cell Replacement Battery for Asus U20 U30 U50 U50F U80 series laptops

This brand new Asus Extended run replacement laptop battery features lithium-ion cells. Li-ion battery technology provides longer run times with less weight. This battery is physically larger than the original. If your laptop's display screen rolls over the hinged end of your laptop chassis, you will not be able to use this battery. This extended run battery protrudes to the rear of the laptop about 1 inch. If your laptop screen rolls over behind the laptop chassis, the battery pack will prevent your screen from opening to it's full potential. If you have one of these models you will need to use the standard 6 cell battery which does not extend beyond the chassis. A link to the standard size battery is listed below. This laptop battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 2 Year warranty.

How to care for your ASUS U20 U30 U50 U50F U80 battery battery.

You can extend the life of your ASUS U20 U30 U50 U50F U80 laptop battery significantly through the proper care and handling of your battery.

  • Any new laptop battery should first be fully charged by leaving it plugged in overnight. Once a computer battery is fully charged it will no longer accept any more power. It is a common practice to leave laptops plugged in after they have been turned off so that the Asus battery has a full charge the next time you use your laptop. It is probably fully charged within 5 hours.
  • A brand new notebook Asus battery is in a weakened condition since it has not been conditioned yet. Condition and break in your new battery by performing 5 partial discharge and recharge cycles the first week you receive your new battery.
  • Run on battery power without the AC adapter cord at least once a week to keep the battery cells active and at their peak potential. When your laptop is plugged into the power adapter the battery goes to "standby mode" while your laptop runs directly on electricity from the wall outlet.
  • Even though your Asus battery indicates it is fully charged, your battery will return to a weakened state again in a few months if it does not get some exercise through partial discharge and recharge cycles while running on battery power alone.
  • If your Asus battery has not been actively used 2 months or more, condition your battery again with 5 partial discharge & recharge cycles to increase the batteries capacity and run time.
  • Don't run your battery all the way to empty. Your battery will have a longer service life if it receives shallow discharge and recharge cycles. Research has shown that the useful life of the Asus battery will be much longer if you begin to recharge the battery any time before reaching 20% of the remaining power capacity. Recharging the battery even after 10 minutes will not reduce the battery's life span as lithium batteries do not have the memory effect which was found in older NiCad battery technology. NiCad batteries have never been used in laptops, even the earliest models.
  • Never run your Asus battery below the 2% critically low warning point. If your battery is run below this point it may not have enough energy to even recharge. This may effectively "kill" your battery.

How can I extend my ASUS U20 U30 U50 U50F U80 battery run time?

You can extend your ASUS U20 U30 U50 U50F U80 battery run time by minimizing the power drain on your battery. A 6 cell battery will run approximately 2 to 2-1/2 hours when the battery is new. Even longer times can be achieved by minimizing the power consumption of your laptop. Here are the top ways to reduce your power consumption.

  • Reduce the brightness of your Asus U50A laptop screen. This is the number drain on your battery by far.
  • Avoid using the CD or DVD drive as the motor consumes a fair amount of power.
  • Turn off your wireless finder if you are not using the internet.
  • Remove any devices plugged into your USB ports or other ports.
  • Close out programs you are not using. By minimizing the load on your CPU, sometimes you can avoid having the cooling fan turn to its high speed mode.
  • Increase your memory to 4 Gigabytes. This creates less work for your hard drive. Data is temporarily written to your hard drive when your memory is not sufficient to hold all the data on the many pages you may be accessing.
