Surface Pro Battery

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 surface pro 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 (4060mAh 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).

• 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.

• 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 surface pro 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 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 to check laptop battery life.
  You can check your computer’s remaining battery life by clicking your battery icon or accessing the “Power Options” section within your computer’s 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 surface pro battery prices 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.
