Best Practices to Maintain your Laptop Battery

Today we discuss the best practices to maintain your Laptop Battery.
What is the point in carrying a laptop with you somewhere if the laptop battery will only last for 15 minutes and you will end up plugging it in anyway?
More and more laptops are being released with high capacity batteries as an add on option (which I think is money well spent for any one who expects to travel with their laptop) but the battery you get with your laptop may only last a couple hours at best. In addition to this, over time your laptop battery life will depreciate as you charge and discharge it.
It’s not all bad news though, there are a number of best practices that you should consider that will keep your laptop battery healthy for longer, here are a few of the key ones:
  1. Fully charge new batteries before use.
  2. A laptop battery’s health deteriorates the more you charge and discharge it, running it from a power source will make your battery remain in a state of charge/recharge. Instead, when your battery gets to near 100% charged, unplug it from the power and plug it in again when it is low.
  3. Heat will dramatically affect battery life for both batteries in your laptop and spare batteries you have stored. Keep spare batteries in a cool place and try to make sure that your laptop has plenty of ventilation so that the battery does not get too warm. Keeping the laptop cool will also reduce the need for your fan to run which also uses more battery power.
  4. If you are using your laptop as a desktop replacement, consider removing the battery and just running the laptop directly from the power source.
  5. Store spare batteries with approximately 40% charge, batteries even when stored will discharge over time.
  6. Adding more RAM to your laptop will actually decrease battery consumption as RAM will be used rather than your hard drive to run resource intensive processes. Your hard drive is a mechanical device and is a significant power hog.
  7. Try to minimize CD/DVD drive use. As with your hard drive, your optical drives are a mechanical device that will consume a lot of power when in use.
  8. Try using ReviverSoft’s Battery Optimizer to manage your laptop’s devices that can be turned off to maximize battery life.

We hope that you found these tips useful, some of these best practices for maintaining battery life are difficult to follow for some but just knowing them is valuable for you so that you can follow them when possible.

  • I’m interested by this post, I wanted to read it to check I was doing the right things to prolong my batteries lifetime and capacity as I’ve often advised others on this in one way or another. The points about temperature and battery storage are spot on.

    I’m pondering the second point though – it seems a bit contradictory. You say “A laptop battery’s health deteriorates the more you charge and discharge it” which I’d agree with. There are a finite number of discharge/charge cycles a battery will give so surely then you would want to avoid unnecessary cycles? However you seem to be recommending that the battery be discharged (even if power source is available) until it needs charging and then recharged. Wouldn’t that be one unnecessary cycle?

    For example if I’m using my laptop in the office all day (say 8hrs) then this would be about 3 discharge/charge cycles whereas if it was plugged in all day surely this would only be a max of 1 cycle as it was brought up to full charge.

    Can you explain your thinking?

  • Great question and yes you are correct about each battery having a expected lifetime of charge/discharge cycles. Typically most batteries have an expected life of somewhere between 500-2000 charge/discharge cycles before the battery needs replacing. For most people this will mean that their battery will last 2-3 years.
    Now in regards to your example, please refer to tip number 4 in this case. The problem with keeping your laptop plugged in all day is that it will remain in a constant state of charge/discharge which will speed up the deterioration of the battery. The best way to manage a full day in the office using your laptop would be to remove your battery so that you use no charge cycles during that day. This may not be practical for come people so we would recommend unplugging the battery when it is fully charged and then plugging it in when it is getting low.

    How do you currently manage your battery when using your laptop all day?

    Personally, when I used to use my laptop at the office in a docking station with the battery installed it only took a year before my battery life went from originally lasting 3 hours to only lasting 40 minutes.

    Interested to hear your thoughts, especially with your testing background.

    I was doing the wrong – all day charging and discharging. The problem is when the power supply goes out, you might loose very thing. Will you have to get a UPS in case you have to get your laptop battery out in order to save your information while working and the power source goes out?

    go et vive lamour merci!

  • Great question! Yes a UPS would be a very good idea to protect yourself from data loss. This generally a best practice whether on a laptop or desktop. As always, saving your work every 5 minutes can save you a lot of frustration later on!
