FAQ’s (and answers) regarding notebook computer batteries

Q: What is the ‘run-time’ of this battery? How long will my notebook computer stay ‘powered’ with this battery?

A: Run-times vary based on the individual notebook computer, the applications being used (ie: high graphic games), number of times something is saved or retrieved from the hard drive and/or CD ROM drive/floppy drive. The average runtime for a ‘healthy’ battery is 2.5 hours.

Q: What is the life expectancy of a notebook computer battery?

A: A battery typically lasts between 12 and 18 months. The life of a battery is measured in charge/discharge cycles; NiMH & LiIon average 400 cycles.

Q: Why does the battery power my computer for only 5 to 10 minutes?

A: If this a NEW battery, it needs to be ‘conditioned’. A new battery must be charged and discharged (drained) three to four times before it will reach its highest potential.

*** If the battery is over 12 months old, it is time to replace the battery.

Q: Why doesn’t the battery charge overnight in my notebook computer?

A: Make sure the notebook computer is receiving power. (Is the cord plugged in correctly?). When the battery is installed in the computer and it is properly plugged in to an AC outlet, check to see if the ‘fuel gauge’ is showing a charging sign. If this does not fix the problem, the battery, the power source in the notebook or the AC power cord may be defective.

Q: Why won’t my computer start-up (wake-up) with the battery inserted?

A: Make sure the battery is inserted correctly. Make sure that the battery has a charge. If this does not work, consult your computer manual.

Q: Should I leave the battery in the notebook computer if it is going to be plugged in for long periods of time?

A: To increase the lifetime of the battery, it is best to remove it from the computer if the computer will be plugged in for long periods of time. If the battery remains in the computer, it will constantly be charging, which reduces its lifecycle.

*** By removing the battery, you will be eliminating the automatic battery back-up. It is only recommended to use the computer without a battery if the computer will be plugged into an Uninterruptible Power Supply (UPS) in case of power fluctuations or blackouts.

FAQ’s (and answers) regarding notebook computer batteries

Q: Why won’t the battery charge in the external charger that charges the original battery that came with my notebook computer?

A: If the battery will charge in the notebook computer but will not charge in the external charge, then the battery and the charger are not compatible. If the battery will not charge in the external charger AND it will not charge in the notebook computer, then the battery is most likely defective.

Q: The battery will run my computer but the ‘fuel gauge’ does not register anything or it shows a ‘question mark’. What is wrong?

A: You may need a ‘Smart’ battery which will interface with the computer’s software. Not all batteries have a ‘Smart’ option. If there is a fuel gauge, then there is a ‘Smart’ battery available. Most newer notebook computer batteries are ‘Smart’ which means that they have internal microprocessors that will allow the battery and the computer to communicate.

Q: Why does the battery get hot in my notebook computer?

A: The battery may have a defect. Take the battery out and let it cool. If it continues to get hot when it is put back into the computer, it needs to be replaced.

Q: How can I charge my battery?

A: Install the battery into the computer and keep it plugged in for 4 to 8 hours, or it can be charged by an external battery charger that is specifically designed for that battery.

Q: What is the warranty?

A: All BTI Notebook Batteries include a warranty of one year (12 months) from date of purchase.

Q: Will a BTI Notebook Battery void my equipment's warranty?

A: Under the Magnuson-Moss Warranty Act, a manufacturer may not require the use of any brand of replacement part (including their own brand) unless the manufacturer provides the item free of charge under the terms of their warranty.

*** Apple, Compaq, Dell, HP, Lenovo IBM, Sony, Toshiba and most other OEM’s sell replacement batteries for their notebooks.
