The battery of your laptop is one of its most vital components thus one of the most important to keep healthy. Although we mostly tend to think of other hardware first like RAM, screen resolution, and CPU power.

When we talk about laptops, we forget that the battery is the powerhouse of the laptop, and without it, the laptop would be anchored to an AC outlet.

So in this article, we’re going to cover how to keep a laptop battery healthy. Doing so will avoid laptop owners having to replace their batteries sooner than actually needed.

Let’s take a look at the quick answer, thenwe’ll dive into more details…

How to keep a laptop battery healthy? Avoid leaving your laptop plugged in, avoid overheating, avoid draining the battery completely, and adjust power settings for best power use in your settings. Dim the screen and disable wifi and Bluetooth to prolong your battery time and check to make sure your battery isn’t already damaged.

Here are some useful laptop batterycharging tips for people who wish to get the most out of their battery life.

Should you leave your laptop plugged in all the time?

This is a question that laptop owners askquite frequently and the answer to this is a simple no.

In order to get the most life out of yourlaptop battery, keeping it charged somewhere between 40% to 80% has beenobserved as optimum. With newer batteries, however, the charging stops at 100%,but for older batteries, you wouldn’t want to leave your laptop charging allthe time

The new generation of lithium batteriesperform better in full charge cycles, thus not letting the battery drop below40% is a safety measure.

Also, because leaving laptops on charge allthe time could cause the battery to overheat – in some models, which is adanger you should obviously look to avoid.

In many laptop models, once the battery isfully charged, it will automatically cut off the power supply to the battery.Thus keeping it plugged in is unnecessary after that point, however, it won’tlet the battery overheat in most cases.

Should the laptop battery becompletely drained before re-charging?

This is another frequently asked questionwhen it comes to charging the laptop battery. The answer to this is no as well.Most of the newer generation laptop batteries are either lithium-polymer orlithium-ion, and they’re designed to have the ability to withstand repeatedcharge cycles.

As mentioned above, keeping your laptop plugged in at all times wouldn’t necessarily damage your battery, but since laptop batteries do have a limited number of charge-discharge cycles, therefore letting your laptop battery completely discharge is extremely likely to reduce its intended lifespan.

Charging tips for laptops

Not all laptops have in-built removablebatteries for cool-down. Also, internal cooling fans break down after a coupleof years.

Below are some useful battery charging tipsthat will help laptop owners help maximize their laptop battery life:

  • Avoid discharging the laptopcompletely after charging it. The best practice is to try to keep the batterypercentage between 40 to 80 percent. This is especially true for older laptopbatteries.
  • Make sure that your laptop doesn’t overheat and the cooling fan is fully operational. The battery of your laptop is unlikely to overcharge and harm itself because of excessive charging. It has been designed to bypass the charging energy.
  • Batteries that are charged tofull 100% have only 300-500 discharge cycles. Those that are charged up to 80%get nearly quadruple the number of recharging cycles.
  • Performing battery backup,disabling unused ports and devices, and selecting battery saving or eco modewill put your laptop into lower power modes and help prevent unnecessarybattery drainage too.

Of course, these charging tips and thetechniques we’ll provide later for improving your battery’s life will meanlittle if your battery is already on its way out. So it’s helpful to know ifyour battery needs replacing.

How to tell if your batteryneeds replacing!

There are two main ways to diagnose if yourbattery needs replacing.

Battery test – method one

The first way to test your laptop’s batterycan happen right there on your computer. Take the following general steps (obviously,the process will vary slightly, depending on your operating system):

  • Unplug the power cord.
  • Turn off your laptop using the powerbutton.
  • Restart the laptop by pressingthe power button
  • Once powered up, press the Esc key straight away
  • Once the Start-Up menu appears select SystemDiagnostics.
  • A diagnostics list and componenttests should appear – select Batterytest
  • Replug in the power cord
  • Click the Start Battery Test button

Once the battery test has been completed bythe system, you should then be presented with a status message, such as OK, Calibrate, Weak, Very Weak, Replace, No Battery, or Unknown.

In order to further diagnose the system andtake the next action required, you ideally need to then consult the model’smanual that came with the laptop or that is available online.

Battery test – method two

The second method is of greater use if yourlaptop is not performing correctly. It will help understand if any issuesyou’re encountering lie with the battery alone, or beyond that into the laptopinstead.

If your laptop isn’t working properly, weneed to take the battery out of the equation and see what happens, here’s themethod…

  • Carefully remove your laptopbattery
  • Run your laptop using just theAC power outlet adapter
  • A problem is more likely to bewith the battery if your laptop runs perfectly well on just the AC power alone

Note, the removal of your laptop battery may, in some cases, impact yourwarranty status. In order to find this out, you may need to check with thesupplier or manufacturer of your laptop for advice.

Techniques for improving your laptop’s battery lifeDim the Screen

One of the biggest power drains on laptopsis the screen, more specifically, the backlight of the screen. This is whatallows you to see colors on an LCD screen.

Some older laptop models have power-suckingfluorescent backlights. Whereas newer models have LED backlights, however eventhose drain a fair amount of battery.

Dimming the brightness of your screen canadd up to 30 minutes or more to your overall battery life.

Typically all laptops have keyboardshortcuts to adjust brightness levels. To do so one can hold the Fn key and press either one of thefunction keys in the top row of one of the cursor keys.

These keys are found labeled with sunsymbols. The one having the outline of the sun is to be used to make the screendarker.

If your laptop does not have these orthey’re not operational, go to the action center of Windows 10 by pressing the Windows key and hold A. There you’ll find a brightnessslider at the bottom.

If your laptop has an older version ofWindows, then press Win+X. This willautomatically open the Mobility Center from where you can adjust thebrightness.

Disable Wi-Fi and Bluetooth

Disable both, or either of the Wi-Fi and Bluetooth features if you’re not using them. Both these functions drain battery power, therefore it’s sensible to turn them off.

Most laptops out there have a key or switchcombination to disable Wi-Fi, however, Bluetooth might be trickier, for thatyou may need to consult the manual of your particular machine, or search onlinefor the answer.

If your laptop has Windows 10, it’s quitesimple: simply go to the Action Centre bypressing the Windows key and hold A, and then click the Wi-Fi and Bluetooth icons to disable them.

For older laptops, you might find ashortcut, often present in the Start menu, for enabling or disabling Bluetooth.

If still in doubt, you can go to the Control Panel, click the device manager, then scroll through the list of hardware. When you find the Bluetooth adapter, right-click on it and choose Disable. Double-clicking on the icon when it is disabled would enable it again.

Changing the Power Settings

Your laptop is likely to be set to Windows’‘Balanced’ setting rather than the Power Saver mode by default.

To change your power mode settings, you need to Access the Control Panel, and then search for Power Options and see which Power Plan is selected.

Keep in mind that Windows use differentperformance and power settings depending on whether it’s running on battery ormains power.

Find a batterysaver option, then simply select it and close the window. You can alsoclick on ‘Show additional plans’. Ifnothing is still available to be found, then the best option is to customize apower plan by clicking the Change plansettings option.
