The following FAQs are some of the most common questions our customers meet before purchasing a product. Please contact our customer service department if you have other questions.
How long will the new battery power my laptop?
The best way to determine how long a new battery will last is to follow these steps:
Find the capacity of your current battery.
e.g. 1000 mAh.
Think back to when your current battery was brand new. How long did it used to last in minutes? It's important to think when it was new as all batteries deteriorate with age.
e.g. about 60 minutes.
Divide the total minutes (Step 2) by the capacity of your current battery (Step 1)
e.g. 60/1000 = 0.06
Multiply the results from Step 3 by the capacity of the battery you are looking to purchase.
e.g. if the new battery was 1200 mAh you would calculate as follows 0.06 x 1200 = 72 minutes
Your battery has a different voltage to my battery, can I use it?
When replacing your laptop battery, you should always choose a battery with the same voltage as your original. There are however a couple of exceptions to this rule; For example voltages from the same pairs below, are compatible:
3.6V / 3.7V
7.2V / 7.4V
10.8V / 11.1V
14.4V / 14.8V
21.6V / 22.2V
I have seen different battery cell types like 6, 9, and even 12 cells, what are they?
This number indicates the number of individual cells used to make up the laptop battery. The more cells, the higher the capacity of the battery. Generally, the battery with the lowest number of cells is the standard battery that came with your laptop. The 9-cell or 12-cell batteries are the extended, higher capacity batteries that will provide you much longer run-time on a single charge. Before purchasing a battery with more cells, you need to weigh up the benefits vs the extra size and weight, especially if you carry your laptop around with you all day.
My new battery isn't charging. Is it defective?
Usually NO. New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity.
It is generally recommend an overnight charge (approximately twelve hours). It is normal for a battery to become warm to the touch during charging and discharging.
When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not “broken in”. Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.
The Do's and Don'ts of Battery Use
Fully charge/discharge battery up to 3 cycles before achieving full capacity of a new battery.
Fully discharge and then fully charge the battery every two to three weeks for battery conditions.
Run the 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 the user's manual.
Remove from the device and stored in a cool, dry, clean place if the battery will not be in use for a month or longer,Recharge the battery after a storage period.
Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.
Do not short-circuit. A short-circuit may cause severe damage to the battery.
Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
Do not expose the battery to moisture or rain.
Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.
My laptop battery won't charge when plugged in
Laptop computers are designed to recharge the battery while the laptop is plugged into the AC adapter "brick." After a period of time, however, the battery may begin to fail to recharge fully, may seem to have a shorter charge-life or may no longer charge at all. This is quite common: Laptop battery technology just isn’t in place yet to guarantee long battery life and flawless performance.
Unfortunately, there may be little you can do to revive a really dead battery except to replace it.
Remove the battery from the laptop. Look at the sides of the battery. You may find a small panel with three or four LED lights or some kind of labeling referring to battery life. Depress the button or part of the panel that appears to light the LED lights. If your battery is functioning normally, you will see one, two or three “light bars” indicating the amount of charge left in the battery. If none of the lights appear when you test the battery, chances are the battery is dead and can no longer take or hold a charge.
Place the battery back into the laptop. Turn it on, using AC adapter power. When the desktop boots, look for the battery indicator icon in the lower right hand corner of the screen, down near the clock. You should see a battery picture. Hover your mouse over this icon to see how much power is left in the battery. Windows should tell you that the battery is now charging. If there is a red X over the battery, the battery has no charge at all and is probably dead.
Go to “Start,” “Control Panel” and “Power Options.” Check the battery recharging tab. If the battery is able to take a charge, there will be an indicator that charging is happening now. If the battery can no longer take a charge, there will probably be a red X over the battery icon. Shut down your laptop.
Remove the battery and place it in a plastic bag with a zipper lock. Place the battery in the freezer compartment of your refrigerator for 24 hours. At the end of the 24 hours, remove the battery from the freezer and let it “thaw” for two hours. Put the battery back into the laptop (being certain that it is completely dry first). If you’re lucky this freezing may bring the battery back to life—at least for a short time. If the battery is still dead, your diagnosis is over.
Replace the battery if all else fails. Visit the site of your computer's manufacturer for the exact replacement battery for your make and model of laptop. Buy only new batteries.
How can I maximize the performance of my battery?
There are several steps you can take to help you get maximum performance from your battery:
Prevent the Memory Effect - Keep the 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 the 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 the portable device.
Exercise the Battery - Do not leave the 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, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.
