Batteryeshop.Com Tips&Blogs

  • Achieve Maximum Laptop Battery Performance on the Road
  • Laptop batteries are crucial when working on the road. To get maximum performance from your laptop battery, fully optimize the laptop's power management features prior to use. However, there is a trade off when setting your laptop power management. You will achieve better power conservation in exchange for lesser computing performance. The power management system conserves the laptop battery power by setting the processor to run at a slower speed, dimming the laptop screen, slowing down the hard drive when it's not in use and causing the machine to go into sleep or suspend mode when it is inactive. Your laptop user's guide will provide information relating to specific power management features.
  • Increase your Laptop Battery Life
  • Did you know that detaching your main laptop battery from your laptop would increase your laptop's battery life up to 75%? Our experience and testing have shown that even when you are plugged in with your laptop ac adapter and your battery is fully charged, the laptop will still use the laptop battery resources in small increments. This will put unnecessary charge cycles to your battery. Since typical li-ion laptop batteries have 375 charge cycles, having a fully charged battery inserted will put unnecessary charge cycles. The downside to removing your laptop battery maybe a loss of power when the ac adapter is accidentally unplugged or when there is a power outage.
