6 months. Our inventory turns rapidly and you will always receive a freshly manufactured battery.
How to care for your PA5209U-1BRS battery.
You can extend the life of your 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 battery
has a full charge the next time you use your laptop. It is probably
fully charged within 5 hours.
- A brand new notebook 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 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 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 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 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 PA5209U-1BRS battery run time?
You can extend your battery run time by minimizing the power
drain on your battery. Even longer times can be achieved by minimizing the
power consumption of your laptop. Here are the top ways to reduce your
power consumption to prolong the PA5209U-1BRS battery run time.
- Reduce the brightness of your 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.
