FAQ about battery
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 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.
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.
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.
