How To Care For Your Non-Removable Laptop Battery

Andy Betts 23-06-2015

More and more laptops are designed with non-replaceable batteries. MacBooks, Ultrabooks running Windows, and Chromebooks — no matter what the price point or platform, non-removable batteries are becoming the norm.


In some respects, this is a good thing. These laptops are slimmer and sleeker than ever before, and with low-power processors and fanless designs Intel Core M: What's so Great About the Processor?

But it also gives the laptop a limited lifespan, with the prospect that the battery dies when the rest of the hardware is still going strong How to Keep Your Laptop Powered Even When the Battery Dies Have you ever had your work interrupted by a dead laptop battery? Don't let a lack of power put a damper on your productivity. Read More .

So what precautions should you take to ensure your non-removable laptop battery last for as long as possible?

Watch The Heat

One of the main factors that affects the life of a laptop battery is temperature. Cold temperatures can be an issue if you live in a cold climate, but high temperatures are a bigger concern.


Not only are ambient conditions at work — including things like leaving your laptop in a hot car — heat is also naturally generated by the computer’s processor and other components.

It’s often recommended that users remove the batteries from their laptops Should I Remove My Laptop Battery To Increase its Life? Does running your laptop on AC power damage the battery? Should you remove the battery to increase its lifetime? You've probably wondered about this. Find out the answer now! Read More when playing high-end games, editing video, or performing any other resource intensive tasks. However this isn’t possible for models where the battery isn’t removable.

Many of these use lower power components, such as the Intel Core M processor, which are designed to generate less heat. You should also make sure air can circulate around the laptop, keeping any vents clear and not resting it on a cushion. Try and keep it under 35 degrees Celsius.

Charge and Discharge


A common question about laptops is whether it’s better to use them on battery power, or leave them plugged in all the time Should You Leave Your Laptop Plugged in All the Time? Is it better to keep your laptop plugged in, or use it on battery power? Turns out, the answer isn't entirely straightforward. Read More .

The short answer is, a bit of both. Unibody Apple MacBooks all have sealed batteries, and the company recommends switching between the two on an occasional basis. If you mostly use your laptop in the office, for example, then leaving it plugged in is fine, though you should make a point of running it off the battery every now and then.


Batteries cannot be overcharged, so won’t be damaged directly, but it’s important to remember that charging is yet another source of heat.

Don’t Let It Run Down

If you’re running your laptop off battery power, you should ideally avoid fully discharging it — or even getting below around 20% — on a regular basis.

Tests from show that it can take as few as 300 complete discharges to reduce a laptop battery’s capacity to 70%. This compares to as many as 1500 discharges to a level of 50% before the battery’s lifespan is reduced equally.

That said, many manufacturers do recommend that you perform a full discharge every few months to help keep the battery properly calibrated and to ensure the stats it reports are accurate.

In Windows, you can explicitly prevent the battery from dropping below a certain level. It’s well-hidden, but go to Control Panel > System Maintenance > Power Options > Select a power plan and click Change plan settings. Choose the Advanced settings, then battery, and under Low battery level and Critical battery level change the values to a percentage that you want.

Keep It Charged

The charge level of your battery is also important even when you’re not using your laptop.

HP recommends that batteries should be stored with 50-70% charge at temperatures between 20-25 degrees Celsius. If you won’t be using your laptop for a while, try and keep it in as close to these conditions as possible.

How Long Will Your Laptop Battery Last?

It’s an unavoidable fact that the capacity of a laptop battery declines a little every single time it is charged.

ASUS states that its batteries have a lifespan of between 300 and 500 charge cycles (which is typically measured as using the full capacity of a battery — so a single 100% charge, or two 50% top-ups), after which the capacity will have dropped to 80%.

It isn’t necessarily a bad thing, you just need to be a little more aware of how you look after the battery than you may have done in the past.

There are no major steps to take. A few common sense precautions and being aware of the factors that can shorten a laptop battery’s life will ensure your battery lives a long and healthy life.

    This article is not specifically for non- removable batteries. I was finding when tips about non-removable batteries come and the article ends without having them. Even I'm surprised this article is ranking good in Google search engine.

    Can you still open your laptop with built in battery even if it is damage and still insert inside the laptop?

    This article is a perfect example of useless, poorly researched drivel morons copy and paste into blogs. I'm writing this comment on a Lenovo G50-45 laptop. It has the Lenovo Energy Manager App that includes Conservation Mode. Turn CM on and the battery STOPS CHARGING at 55 -50% state of charge when the lap top is plugged in. That's right boys and girls, when I use my laptop at home it's always plugged in by the battery stays at the optimum state of charge. When I want go somewhere and use my laptop on battery power, I turn Conservation Mode OFF and charge the battery to 100%. When I get back home or to the office, I plug in and turn Conservation Mode ON. Lenovo's app is called Energy Manager in Win 8.1. I also have the same function on another Lenovo G50-45 that came from the factory with Win 10 . Lenovo might have changed the name of the app, but it's there on Win 10 machines and functions identically

    I haven't found the same battery management software on any other manufacturer's laptops and would not buy a laptop without it. I also avoid built in batteries, but if you buy a laptop with a built in battery get a Lenovo and use Conservation Mode.

    I own two G50s because after buying the first one, I found out it was the last $300 laptop with a removable battery and an easily removable hard drive. Most of the $300 laptops like the HP 15 have the hard drive buried in the middle of the chassis. You have to remove the optical drive, keyboard, etc. to get to the HD. I clone my drive for back up. If I experience a crash or other HD problem, I pull last night's clone out of my safe, removethree screws from the back of the G50 and the HD is right there. I'm back up and running in 10 minutes. I found out that Lenovo's current $300 laptops have built in batteries and buried HDs so aA few months later I bought another new one with Win 10 on it as a back up.

    The market doesn't care about these features because most people use computers for email, YouTube and social media. They NEVER back up and buy a new laptop when the battery dies or HD crashes. If you actually do any work on your laptop, you'd be a fool not to spend a few more dollars on a removable battery and easy to get to HD. IF YOU WANT YOUR BUILT IN OR REMOVABLE BATTERY TO LAST, GET A LENOVO WITH ENERGY MANAGEMENT/CONSERVATION MODE.

      I feel the same way with lenovo laptops. Agreed that battery management is important. In order for a laptop to last, first thing to go is battery. If there is detachable battery, good for a longer lasting laptop.

      One should be "aware of how you look after the battery", but "There are no major steps to take.". Yes, pointless article.

    Thanks for the Windows tip about "powercfg /batteryreport".
    It helped me see how battery capacity decreased over the weeks. I guess I will try not to discharge my battery below 20%.

      If you fully charge your laptop and keep it plugged in, it should run on ac only without drawing anything from the battery.
