Help me choose: Battery

 

Dell’s Lithium-ion (Li-ion) batteries offer fast charging and long life to help keep you mobile and productive when you are on the go. For extended battery life, choose a primary battery that can keep your system powered longer when it is unplugged from an electrical outlet.  

Battery 
The actual life of your battery will vary depending on a number of factors, including battery size, system configuration, individual usage, number of batteries and manufacturing variability.

If you spend extended periods away from an AC outlet, Dell recommends adding a secondary battery when you configure your system. In addition, you can conserve your battery charge when you are not mobile by using an AC adapter.
Battery life and battery lifecycle.

Battery life is how long your battery will last between charges. Battery pack lifecycle is how often a battery can be recharged before its charge capacity starts to degrade (for example, when a fully charged battery is reduced to 60 percent of the original battery charge capacity). This reduction of charge capacity in turn leads to a significantly reduced battery life. The reduction in charge capacity is normal on all rechargeable batteries.

Extending battery life

The easiest way to get the best battery life out of your Dell laptop is to select one of the pre-configured power plans, such as Power Saver or Balanced by right clicking on the battery symbol in the bottom right corner (aka system tray). The preconfigured power plans automatically adjust key settings that can have a significant impact on battery life, such as reducing screen brightness or dimming the display when you are not actively using your laptop.

For those who need to extend battery life as long a possible there are a few additional steps you can take that will help extend battery life, such as:

  • Turn off wireless — The F2 key is the quickest way to toggle wireless on and off. If you don’t need to be connected, then turning off wireless will help extend battery life
  • Limit workload — If you limit the number or applications you have running, or the number of windows or tabs you have open, this can help extend battery life.
  • Selective usage — Batteries will last a lot longer if you are reading emails and editing documents than if you are watching a movie or playing a video game.

Extending battery lifecycle

For select laptops introduced in 2012, Dell has taken steps to extend the battery pack lifecycles of user replaceable and built-in battery packs. Dell has battery packs designed to last up to 600 full discharge/recharge cycles.* Purchasing a laptop with a 600 cycle battery pack may reduce the number of battery packs you need to purchase (and discard) and may help reduce your contribution of hazardous waste to landfills.
