Finally, you can check whether the battery you find is compatible with your laptop or not on the "Compatibility" table (for example, Lenovo ThinkPad P72). If you don't know how to find the right battery for your laptop, you can click "How to find one correct battery for my laptop?" for more details. Moreover, you can click the link "Contact Us" on the bottom of this page to ask us.

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.
It is important to check the dimensions and weight in addition to the capacity because sometimes higher capacity batteries can be larger in size, making them impractical for some uses even though they are compatible.

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 www.secure-battery.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 'volume' 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 & 3.7 volts. (3.6V & 3.7V are used interchangeably and refer to the same amount of voltage.), each battery cell has a capacity of 2000 ~ 2200mAh.

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

How to calculate battery cells?

e.g. a laptop battery is 10.8V/4400mAh,
3 x 3.6V = 10.8V
2 x 2200mAh = 4400mAh
3 x 2 = 6 cell battery

e.g. a laptop battery is 10.8V/6600mAh,
3 x 3.6V = 10.8V
3 x 2200mAh = 6600mAh
3 x 3 = 9 cell battery

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.

Tips:

  1. It is recommended that you do one full drain and charge every three months to maintain calibration of your battery.
  2. Turn the screen light down as far as you can and still see, this will make your battery last longer.
  3. Turn off any hardware and programs that you are not using. If you do not need them on, then turn them off.
  4. Turn your power setting down to portable/ laptop or power saver to keep your battery running longer.
  5. Add more RAM so that there is a minimum of hard drive access.
  6. After storing a laptop battery and re-charging, it may only re-charge for 10-15 minutes and then claim the notebook battery is fully charged, this is a common phenomenon in rechargeable laptop batteries, to overcome this simply remove the laptop battery and then re-insert it to initiate the charging process again.

Warnings:

  1. Having your computer automatically run updates means that there are things continuously running when you don't need them to be.
  2. Running CDs and DVDs while your battery is not on the charger will drain faster.
  3. Don't play games on your computer when the battery is off the charger, it has to work harder to run all the graphics and other necessary programs.
  4. Never connect a laptop to an automotive power supply adapter as a substitute for running on the laptop battery. You likely will damage or destroy your laptop.
  5. Lithium Ions can be ruined if the voltage drops below a certain level, avoid letting your notebook battery drain completely and repeatedly.
  6. If you plan on not-using the notebook battery for a month or longer then fully charge the laptop battery, then store it in a cool place. The laptop battery will lose its charge while stored and will need to be re-charged before you begin using it again.

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.
It is important to check the dimensions and weight in addition to the capacity because sometimes higher capacity batteries can be larger in size, making them impractical for some uses even though they are compatible.

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 www.secure-battery.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 'volume' 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 & 3.7 volts. (3.6V & 3.7V are used interchangeably and refer to the same amount of voltage.), each battery cell has a capacity of 2000 ~ 2200mAh.

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

How to calculate battery cells?

e.g. a laptop battery is 10.8V/4400mAh,
3 x 3.6V = 10.8V
2 x 2200mAh = 4400mAh
3 x 2 = 6 cell battery

e.g. a laptop battery is 10.8V/6600mAh,
3 x 3.6V = 10.8V
3 x 2200mAh = 6600mAh
3 x 3 = 9 cell battery

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.

Tips:

  1. It is recommended that you do one full drain and charge every three months to maintain calibration of your battery.
  2. Turn the screen light down as far as you can and still see, this will make your battery last longer.
  3. Turn off any hardware and programs that you are not using. If you do not need them on, then turn them off.
  4. Turn your power setting down to portable/ laptop or power saver to keep your battery running longer.
  5. Add more RAM so that there is a minimum of hard drive access.
  6. After storing a laptop battery and re-charging, it may only re-charge for 10-15 minutes and then claim the notebook battery is fully charged, this is a common phenomenon in rechargeable laptop batteries, to overcome this simply remove the laptop battery and then re-insert it to initiate the charging process again.

Warnings:

  1. Having your computer automatically run updates means that there are things continuously running when you don't need them to be.
  2. Running CDs and DVDs while your battery is not on the charger will drain faster.
  3. Don't play games on your computer when the battery is off the charger, it has to work harder to run all the graphics and other necessary programs.
  4. Never connect a laptop to an automotive power supply adapter as a substitute for running on the laptop battery. You likely will damage or destroy your laptop.
  5. Lithium Ions can be ruined if the voltage drops below a certain level, avoid letting your notebook battery drain completely and repeatedly.
  6. If you plan on not-using the notebook battery for a month or longer then fully charge the laptop battery, then store it in a cool place. The laptop battery will lose its charge while stored and will need to be re-charged before you begin using it again.
