Yes. The capacity of a battery does not affect its compatibility in anyway. A higher capacity battery will simply power your device for longer before you need to charge it. However, in order to house the extra battery cells, most higher capacity batteries will be physically larger and may lift or stick out of the back of the laptop.
Note: When used under the same conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
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.
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
All of our batteries are brand new. We do not sell old, used or refurbished battery cells. We use only the best battery cells, grades and components in all of our batteries for you safety and value.
No. We use the same quality components as laptop manufacturer's use in their batteries. The only difference is that our batteries are not labeled or branded.
Even the Leading Name Brand Laptop Batteries Are Manufactured Using Components From Third Parties.
Consumers often view OEM laptop batteries from brands such as Apple, Dell, Toshiba, HP, and others as being superior simply because of the name-brand. The truth is that name brand laptop batteries are manufactured using various components from other companies. Samsung, LG, and Texas Instruments are world renowned for the quality, safety, and lifespan of their battery components and are used in the assembly of most laptop batteries.
We specialized only in laptop batteries and work closely with the manufacturer to produce only the highest quality batteries. Only name brand battery cells and circuit boards are used in our batteries. Our prices are so much lower than OEM batteries because we manufacture our own casings and cut out the costs to brand or label our batteries, which in turn reduces any additional cost to our customers.

In general, a laptop battery will provide between 400-800 life cycles depending on usage and battery quality. Lower quality or poorly manufactured batteries will provide fewer cycles, and a shorter overall lifespan.

  1. Highest Quality Batteries (Grade A Cells) - 12-18 months
  2. Medium Quality Batteries (Grade B Cells) - 10-15 months
  3. Low Quality Batteries (Grade C Cells) - 5-10 months ensures that our world class batteries will perform as well or better than name brand OEM batteries, and will provide you with the longest lifespan and highest performance possible at the lowest prices anywhere.
Actual battery run-time depends upon the power demands made by the equipment such as the applications you are running and your laptop settings. Our replacement batteries will last the same or longer than the original battery which came with the laptop when it was brand new (at the same capacity). Generally, a standard 4400 mAh will last between 45-90 minutes. You can calculate how long a higher capacity battery will last based on the mAh difference. A 7200 mAh battery will give you 64% more run-time, and a 10400 mAh will give you 136% more run-time than the 4400 mAh on a single charge.
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new laptop battery when the run time does not meet your needs.
Every battery has three ratings which are watt hours, volts and milliamp-hours.
Watt Hours (wHr) is a unit of energy equal to the work done by one watt acting for one hour and equivalent to 3,600 joules. The wHr is a calculation of voltage and mAh.
Milliamperes (mAh) is a unit of measure electric power over time. It represents the total amount of energy store in your battery. The mAh rating is also a measure of the number of hours a battery may last. The higher a battery's amp hour rating is, the longer the battery's run-time will be. It is not uncommon for some of our batteries to have higher or lower amp ratings. This will not cause any incompatibilities.
Voltage (V) is the amount of electricity that is delivered to your computer. The amount of energy from your wall outlet is greater than what your laptop needs to operate. Therefore a power adapter contains a box like bar that will decrease the energy lowering the 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. While the voltage of the Hi-Capacity battery may not be identical to the original battery, the voltages must be within a reasonable range. Any replacement laptop battery should always be within +/- 1V. Anything above that range may cause incompatibilities.

While not required, it is recommended to fully charge your battery.
No, with current lithium ion batteries this practice does not improve the runtime of the battery. This practice is a holdover from the days in which NiMH batteries were used.
Usually NO. New batteries come in a discharged condition and it is best to 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.
No, the battery has built in controls which stop the charging process when the battery is full.
There are several things you can do to make your battery last longer :
  1. Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
  2. Dim your screen(The screen is one of the most power-hungry parts of the laptop).
  3. Use the notebook's power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
  4. Using USB peripherals can put a big drain on your system, because your motherboard has to power them, so unplugging everything saves juice.
  5. Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
  6. All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new laptop battery.
