Increase Laptop Battery Life

Turn Off or Disconnect External Plug & Play devices which are connected to your Laptop computer like the External Monitor, Headphones, External Hard Disk Drive, USB Modems, Optical Drives, External Mouse etc which continiously use your DELL J414N battery powered laptop and reduce the backup time.

Disable Bluetooth & Wi-fi – When you dont need any of these 2 options, its recommended to disable them because both of these keep searching for other bluetooth users or wifi routers to connect and this takes up a good amount of your battery life. Once disabled you can find a good increase in your DELL J415N battery life.

Use your Laptops Power saving features under Power Options by visiting Control Panel > Power Options and selecting the option ‘Turn off monitor’ to 1 minute when running on DELL J399N battery because this can save your laptops battery life when you are not using your laptop for few minutes by turning off the laptop’s LCD monitor.

Try to keep your Laptop in a cooler area because the Laptop batteries discharge very quickly if placed in a hot area and if the DELL D608H battery is hot then expect quick discharge and less backup overall

Keep running your laptop on backup mode every few days to make sure that its completely discharged and empty and refilled for better life cycle of the DELL RU586 Battery
