How long a laptop battery should last after each charge?

Laptop battery

After the laptop has gone through a full single charge and the power adapter is unplugged, the average life of a laptop battery can be anywhere between one and six hours. This time is dependent on the battery, its capacity (mAH), what's being done on the laptop, and how old the battery is. Over time, the laptop battery's capacity decreases, which means the battery will not last as long as it did when you first got the laptop and will continue to decrease over time.(cliquez ici pour suivre le lien)">Dell Precision m3800 Battery

The more software programs that are open and running on your laptop, the less time you get from the battery. When more programs are open, it requires more power for the laptop to keep the programs running. Other factors that affect the battery life include the brightness of the screen, an active WiFi connection for Internet service, and if you are consuming media. Each of these will also reduce battery life.(cliquez ici pour suivre le lien)">Dell Precision m6700 Battery

What's the overall life of a laptop battery?

A laptop computer battery should last between two and four years, or around 1,000 full charges. The total lifetime of a battery is dependent on several factors. These factors include battery type (NiCad, NiMH, or Li-ion), how often the battery is used, and its age.Akku HP Elitebook 6930p

A battery is a hardware component that supplies power to a device, enabling that device to work without a power cord. Batteries are often capable of powering a laptop computer for several hours depending on how much power it requires. Today, many high-end devices such as computer laptops and cell phones use rechargeable batteries that allow a user to recharge the battery once depleted of energy. The picture below is an example of a removed laptop battery with a close-up of the battery rating.

Computer batteries

There are three computer batteries types used with computers. First, is the backup battery, which is commonly referred to as the CMOS battery that holds your computer's settings, such as the time and date. Without a CMOS battery you would have to reset the time, date, and other system settings each time the computer starts.

Next, the bridge battery is only found in portable computers as a temporary backup for the main battery. A bridge battery allows you to remove the main battery and replace it with a good battery without having to turn off the computer.Akku HP Elitebook 8440w

Finally, the main battery in portable computers is an alternate source of energy for when the computer is not connected to a wall outlet.
