The Laptop Battery Capacity Explanation

The battery capacity will be better with lower drain currents

. To determine the laptop battery life, divide the capacity by the actual load current to get the hours of life. A circuit that draws 10 ma powered by a 9 volt rectangular battery will operate about 50 hours: 500 mAh /10 mA = 50 hours The cell voltage of alkaline cells steadily drops with usage from 1.54 volts to about 1 volt when discharged.

Laptop batteries are rated by, Voltage (V) and Milliamp-hours (mAh). Voltage is the rate at which energy is extracted from the battery and Milliamp-hours represents the capacity of the battery. The milliamp-hour rating corresponds to the runtime of the HP Pavilion dv4 Battery .

Batteries with different Milliamp-hours can be used in the same laptop provided the voltage is the same. The voltage must match the original HP Pavilion dv5 Battery or as recommended by the computer manual. Using a battery with a different voltage setting can seriously damage the laptop.

The power specifications of most compatible / replacement batteries are higher than the original battery manufacturers. This will not damage your laptop, in fact, simply means that in many cases these Dell Latitude D830 battery last longer than the original battery manufacturers. Ask the experts as

PowerUp on compatible replacement laptop batteries.

The runtime of a laptop battery will vary on individual notebook computers, based on the applications being used (ie high graphics, games), the number of times something is saved or retrieved from the hard drive and / or CD Rom, memory notebook, and chemistry and HP 510 battery capacity. A realistic average runtime of a battery is 1.5 to 3 hours. Using devices like a wireless adapter on the laptop also drains the battery considerably.

The life of a HP 530 battery under normal conditions is about 500 to 900 charge-discharge cycles. This is a year and a half to three years of battery life for the average user. As the rechargeable battery begins to fail, the duration of the battery begins to decrease.
