Buying A Replacement Laptop Battery
Finding a replacement battery can be a time consuming ordeal, especially when you try to buy your battery online. Online battery stores are usually cheaper, but you run the risk of purchasing the incorrect battery model that does not meet your laptop power specifications. This can result in a painful return/refund chain of events at best, wasted time and money if the online vendor does not respond, or even worse, buying a battery that you did not need to begin with. (see below)
Another option would be to buy a replacement battery directly from your laptop manufacturer. But this can deliver a painful punch to your wallet

Correctly Identifying the Problem:
By bringing in not only your old battery, but your laptop as well, you can eliminate the risks and guesswork associated in buying a replacement laptop battery.
We test your power adapter to confirm that it's working properly, and is not the source of the problem (i.e. your battery not charging).
Often times we discover it's not your battery that needs changing but the connector in your laptop (or power jack) that your power adapter connects to. If the power jack malfunctions, the battery cannot receive the power to charge. We will identify this problem and offer our on-the-spot repair services that will replace the power jack.
Knowing that your power adapter and the power jack are fine, we then check your laptop for the correct power specifications, install the new battery, and power it on.
Bingo... you have purchased a power solution instead of a battery.
If however, your laptop's power system still has issues, it could be your power circuits on the main board that have been damaged. This would require you to leave your laptop for further diagnostics.
Bottom line, when your laptop beams, and we see a smile on your face, we let the cash registers ring and join in the smiling.
It is strongly recommended that you bring your laptop and, preferrably, your old battery and laptop AC adapter. This enables us to do a 2-minute check to verify that you actually need your battery to be replaced.
Common Laptop Battery Questions:
Your laptop is an incredible device, but it needs power to run. You can run your laptop connected by a charger to a wall socket, or you can charge your battery and then use your laptop untethered, as a mobile device when traveling or when unable to access a power socket.
New laptops come with batteries that when fully charged typically allow your laptop to work for between 2 and 4 hours. Depending on usage patterns, over 2 to 3 years, as the battery is frequently charged, the power of a fully charged battery dissipates, until it just turns into a heavy paper weight and provides no power.
Time for a new battery.
Can I specifically calculate my battery run time?
You can determine your laptops run time when you know how many watts your laptop computer uses and the total power capacity your notebook battery has. Here is how you can calculate this yourself.
Battery capacity can also be measured in Watt-Hours. Watt-Hours are calculated by multiplying Volts x Milliamperes. Here is an example:
14.8 Volts X 4060mAh (4000mAh is equal to 4.06 Amperes).
Is also equivalent to:
14.8 x 4.06 = 60.09 Watt-Hours
Watt-Hours measure the energy which powers one watt for one hour. If your laptop runs at 20 watts, your run time will be: 3.004 hours (60.09 Watt-Hours / 20.0 watts Laptop pc power use)
Will a higher milliamp (mAh) rating on my battery damage my laptop?
No. Higher mAh ratings indicate that your battery will last longer. Although the milliamps may be higher, the voltage will always remain the same. If you have received a laptop battery that has a completely different voltage than your original laptop battery, please contact us immediately.
How can I extend my laptop battery run time?
Your new laptop battery will have an average run time of 1 1/2 hours to 3 1/2 hours depending on what applications you are running. Functions that require more power will deplete your battery faster. You can extend your battery run time by minimizing the main power draws on your battery - the LCD brightness levels and the use of your CD or DVD drive. Also some notebooks simply use more power than others.
You can prolong your laptop battery life by adjusting the power management selections within your operating system software. If you are a Windows user, you can go to the control Panel and select power options. In this area you can choose when & how you can maximize your laptop battery settings
What do the power ratings mean - mAh, Volts, and Watts?
MAh (Milliamperes) represents the amount of stored energy in your battery. 1000 Milliamperes = 1 Ampere. The more mAh capacity - the longer your battery will last. Several batteries from LaptopBatteryExpress.com have higher mAh ratings than your original battery brand. This does not mean that the battery is not the correct replacement, but rather it is a longer lasting battery. Voltage in a battery refers to the ìvolumeî of electricity that is delivered to your computer. The amount of energy that comes from your wall outlet is far in excess of what you need to operate the tiny circuits of a computer. Hence your power adapter contains a brick or bar like box that decreases the energy to a much lower voltage rating. Each computer manufacturer designs their computers for the appropriate voltage requirement. Your battery pack will then be engineered to match the voltage of the power AC adapter. Laptop battery packs are composed of several battery cells that are wired together in series. By combining the cells in this fashion, higher volumes of energy can be delivered to your laptop computer. For laptop computers, each battery cell has a voltage rating of 3.6 to 3.7 volts. (3.6V & 3.7V are used interchangeably and refer to the same amount of voltage.)
Cells Voltage/Cell Formula Nominal Voltage
1 cell 3.6V or 3.7V 1 cell x 3.6 or 3.7V 3.6V or 3.7V
2 cells 3.6V or 3.7V 2 cells x 3.6V or 3.7V 7.2V or 7.4V
3 cells 3.6V or 3.7V 3 cells x 3.6V or 3.7V 10.8V or 11.1V
4 cells 3.6V or 3.7V 4 cells x 3.6V or 3.7V 14.4V or 14.8V
Watts measure the amount of energy a device uses. This is a rating that will be found on your monitor and laptop PC, - not your battery.
NiCad and NiMH?
NiCad (nickel Cadmium) batteries are best known as the battery type that has the ìmemory effectî. In order for these batteries to work efficiently, the battery must be completely discharged before recharging. If you recharge these batteries while there is still power stored in the cells, your battery will ìresetî itself so that it now only holds the amount of power stored from the last recharge. Many electric tooth brushes, power tools and other consumer items still utilize NiCad battery chemistry. If you have devices with NiCad batteries, you will save yourself some aggravation and money by having a fully charged spare battery to insert while you recharge your depleted battery. NiCad batteries are the least expensive to produce, but because of the memory effect problem, these type of batteries are slowly being phased out with other improved battery materials.
NiMH batteries are less prone to develop this problem and thus require less maintenance and conditioning. In addition, NiMH batteries can store about twice as much energy as NiCad batteries without adding any additional weight. NiMH batteries are also environmentally friendlier than NiCad batteries since they do not contain heavy metals (which present serious landfill problems). Note: Not all devices can accept both NiCad and NiMH batteries.
Lithium Ion:
Lithium-Ion (Li-Ion) has become the new standard for portable power in consumer devices and laptop batteries. Li-Ion batteries produce the same energy as NiMH battery but weigh approximately 20%-35% less. This can make a noticeable difference in devices such as cellular phones, camcorders or notebook computers where the battery makes up a significant portion of the total weight. Another reason Li-Ion batteries have become so popular is that they do not suffer from the "memory effect" at all. They are also environmentally friendly because they don't contain toxic materials such as Cadmium or Mercury.
What is the difference between NiCad, NiMH and Lithium-ion laptop batteries?
Batteries in laptops, camcorder and cell phones are typically made using one of three battery chemistries: Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-Ion) battery cell chemistry.
How long will my laptop battery run?
Average run time is 1 1/2 hours to 3 1/2 hours depending on what applications you are running. Functions that require more power will deplete your laptop battery faster. Viewing a DVD or using your CD player to play and record music are power intensive functions and will consume power at a faster rate. Also different notebooks use more power than others. Most laptops have a power management control panel where power use can be reduced while on battery power, such as reducing the brightness of your LCD screen. External batteries can also be purchased to provided extended power.
How to check laptop battery life.
You can check your computerís remaining battery life by clicking your battery icon or accessing the ìPower Optionsî section within your computerís control panel. Your laptop battery life depends on the power capacity of your laptop battery and the amount of energy your computer draws.
How can I minimize the power my laptop uses?
Your laptop battery life depends on the power capacity of your laptop battery and the amount of energy your computer draws. You can maximize your laptop battery life by changing the amount of power your computer draws while in battery mode. If you are a Windows user, within your Control Panel section you will find Power Options. In this section you can change power use and low power alerts. Windows Vista users will be able to lower the brightness of the LCD panel and extend the battery life considerably. You can also extend your battery life between charges by minimizing the use of your CD and DVD drive operation.
Why does my laptop battery lose power over time?
Over time, laptop batteries lose their ability to hold a charge. This is a normal occurrence and is common to all rechargeable laptop batteries. Most notebook batteries today are made with advanced materials that hold their charge much longer than earlier technologies used just a few years ago. Even so, the life of a laptop battery today will be approximately 500 recharges. For most users, 2- 3 years is a typical life expectancy of a laptop battery.
Is it normal for a battery to produce heat while it is being used and while charging?
It is normal for notebook batteries to produce heat when they are being charged and also when you are running on battery power. As energy is transfered within your battery cells, heat is a natural byproduct.
