How to charge your new FOSA laptop battery?
Your new laptop battery comes in a discharged condition and must be
charged before use (refer to your computer manual for charging instructions).
Upon initial use (or after a prolonged storage period) the battery may require
three to four charge/discharge cycles before achieving maximum capacity.
When charging the battery for the first time your computer may indicate that
charging is complete after just 10 or 15 minutes. This is a normal phenomenon
with rechargeable batteries. Simply remove the battery from the computer and
repeat the charging procedure.
It is important to condition (fully discharge and then fully charge) the
battery every two to three weeks. Failure to do so may significantly shorten
the battery's life (this does not apply to Li-ion batteries, which do not require
To discharge, simply run your device under the battery's power
until it shuts down or until you get a low battery warning. Then recharge the
battery as instructed in your user's manual.
If the battery will not be in use for a month or longer, it is recommended that
it be removed from the device and stored in a cool, dry, clean place.
It is normal for a battery to become warm during charging and discharging.
A charged battery will eventually lose its charge if unused. It may therefore
be necessary to recharge the battery after a storage period.
The milliamp-hour (mAH) rating of the BatteryOnline.org.uk batteries will
often be higher than the one on your original battery. A higher mAH rating is
indicative of a longer lasting (higher capacity) battery and will not cause any
An BatteryOnline.org.uk battery will, in most cases, outperform
the original by 30% to 50%.
Actual battery run-time depends upon the power demands made by the equipment.
In the case of notebook computers, the use of the monitor, the hard drive and
other peripherals results in an additional drain upon the battery, effectively
reducing the battery's run-time.
The total run-time of the battery is also heavily
dependent upon the design of the equipment. To ensure maximum performance of
the battery, optimize your computer's power management features. Refer to your
computer manual for further instructions.
How Can I Maximize My FOSA Laptop Battery
There are several steps you can take to insure that you get maximum
performance from your laptop battery:
Breaking In New Batteries - new batteries come in a discharged condition and
must be fully charged before use. It is recommended that you fully charge and
discharge your new battery two to four times to allow it to reach its maximum
Preventing the Memory Effect - Keep your 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 Your Batteries 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 your portable device.
Exercise Your Battery - Do not leave your battery dormant for long periods of
time. We recommend using the battery at least once every two to three weeks.
If a 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 battery for a month or more, we recommend storing 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 break them in before use. Sealed
Lead Acid (SLA) batteries must be kept at full charge during storage. This is
usually achieved by using special trickle chargers.
If you do not have a trickle
charger, do not attempt to store SLA batteries for more than three months.
For Notebook Users - To get maximum performance from your battery, fully optimize
the notebook's power management features prior to use.
Power management is a
trade off: better power conservation in exchange for lesser computer performance.
The power management system conserves battery power by setting the processor
to run at a slower speed, dimming the screen, spinning down the hard drive when
it's not in use and causing the machine to go into sleep mode when inactive.
