Open macbook pro ready for battery replacement. When your laptop’s battery no longer holds a charge, or if its battery health falls below 25%, it’s time to replace it. Here’s what you can do.

1. Check Your Warranty
   The warranty is the first thing you should check if your laptop’s battery is already defective. That’s because if your service warranty covers battery life and it’s still within the coverage period, then you can have the battery replaced for free.
2. Head to Your Nearest Authorized Service Center
   Whether the warranty is still in force or not, this is the best place to have your battery replaced. While replacement may cost a bit more here, these authorized service centers ensure that you get an original or OEM battery.

These batteries will tend to last as long as the original one in your laptop did when it was new. And since they’re an authorized service center, they know the exact part number of the battery that your laptop needs. That way, you’re sure that they install the correct battery on your computer, avoiding the possibility of frying your laptop due to the installation of an incorrect or incompatible battery.

3. A Little Bit of DIY
   If your laptop is out of warranty and has a removable battery, you no longer have to bring it to the service center. All you need is to find the correct part number and order it from the manufacturer. If the original maker no longer has it in stock, you can also search for OEM parts online—just ensure that you’re buying from a reputable shop and you’re good to go.

To ensure that you choose the correct battery for your laptop, you have to find its part number. You can usually find it printed on the battery itself. Unfortunately, battery part numbers are not usually included in the laptop’s user manual, so you must have the battery on hand to check it. Alternatively, you can contact your laptop’s service center and directly ask for the part number.

But if your laptop uses a permanently installed battery, you would need to disassemble it to get the information you need. Usually, you just need to remove its backplate to access the battery, so ensure you have the right tools available when taking your computer apart.

Once you can see the battery, you can then look for the correct part number and order it. You also have to check how to connect the battery to the motherboard, as that may require additional tools. But if you’re unsure about what you’re doing, it’s best to bring the laptop to a professional.

Before opening up your laptop, you’ll want to purchase the correct battery by looking up your computer model on a third-party site such as Batteries Plus and using the tools to find the brand, series, and exact model of your laptop. Once you’ve landed on the battery type, voltage, and capacity, you can buy it from shop around.

Replacing the battery on every computer is different, but you will always have to unscrew the bottom housing using a Phillips screwdriver with a small head. A standard 01 Phillips head is often too big for laptops, so I use a magnetized 00 head from this pack of bits and pair it with my Black+Decker electric screwdriver for the job.

From there, you will need to apply pressure to pull the back frame off of your laptop. Some people recommend dedicated plastic pries, but I just insert a thin ID card (a credit card or license will do) into the exposed seam and slowly pry open a gap along the edges. After the frame has been separated I gently pull it off using my hands to expose the internals and heat sinks.

Carefully remove the white connector of the battery wiring harness (indicated by the multi-colored wires) from the computer to detach the battery. The black battery is usually held in place by an adhesive similar to double-sided tape—carefully pop it up and out. Take note of the orientation of the wiring harness so that you can easily plug it back into the connector. (With the battery detached and your component slots exposed, this is the optimal time to slot in any additional upgrades you had in mind, say an additional RAM stick or a new SSD.)

Align the fresh battery within the space left by its predecessor. Apply light pressure and reconnect the wiring harness to click it back into the computer.

Reassemble your laptop and turn it on to check that it’s receiving power. If you’ve added RAM or additional storage, you can use Task Manager (CTRL+ALT+DEL) on Windows or System Information on Mac to verify that the computer recognizes the larger memory and storage space.

Even if the battery looks normal on the outside or shows no signs of wear, it could be on its last legs. One sure-fire way to know that it’s no longer working as it should is when it no longer provides the expected battery life.

Most performance laptops can last two to three hours in typical use, while newer devices can more than double that in some cases. If you have the latest Apple M1 MacBooks, you could potentially squeeze more 10-15 hours on a single charge.

But if you’re only getting 15-30 minutes of power from a full charge, then your laptop battery probably needs replacement.

You can further confirm this by looking through your computer’s settings. On Windows, look at the battery icon on the lower right corner of your screen. If you see a red cross over it, with the prompt Plugged in, not charging, you need a new battery.

How to Check Your Battery Capacity on Windows and MacOS
When you spend hours charging your laptop only for it to die faster than it did when you first got it, that’s a clear indicator that you’re facing a battery problem. Checking your laptop’s battery health will rule out whether or not this is in fact the case. While both MacOS and Windows devices will warn you when it’s time to replace the battery with a service pop-up or warning, this message normally comes a bit too late. If you’re noticing rapid battery drain, check on the health of your laptop battery yourself.

If you find your laptop’s battery not performing as it should, but you’re still satisfied with how your computer runs, don’t buy a new device—get a replacement battery instead.

Swapping out the battery is easy on most Windows laptops and MacBooks. With that said, older models can be a pain to work with due to their stronger adhesive.

Laptops are convenient devices to have, especially if you like bringing your work with you. These battery-powered devices let you pretty much accomplish things anywhere, as long as you have ample charge left.
Nothing has more of a direct impact on your computer’s lifespan than its battery. You’ll want to replace your laptop battery when its runtime doesn’t last nearly as long as it did out of the box.
If your laptop isn’t able to hold a charge like it used to, replacing the battery is a simple and affordable DIY fix.

Signs of a Dead Battery
The most glaring sign of a dead laptop battery is when it bloats. If you have a removable battery, you can take it off your laptop and check the seams of its case for signs of cracking. But if you have a computer with a permanent battery, you can look at the chassis for signs of swelling.

These signs can include cracking along the seams of your laptop chassis or bloating near the trackpad or keyboard area. When you see any of these signs, it’s time to replace the battery.

If you can remove the battery, do so carefully. But if it refuses to budge, don’t forcefully remove it. Instead, bring your laptop to a service center and have a professional do it for you. Also, you should not use your computer once its battery swells. Even if it rarely happens, batteries can catch fire or even explode when damaged.

A phone charged between 20% and 80% is ideal for maintaining battery life. Of course, you won’t be able to keep your eyes on your phone’s charge level all the time, but with a little effort, you will get there. It doesn’t say that if the phone comes in at 100% or 10% that’s a big deal, but if the cell phone is in general between 20 and 80% that would be ideal.

Pick the right time to charge it
Don’t let your phone drain completely before plugging it in for the sake of the battery. The ideal would be to do small frequent charges than to do a long charge in one go. Don’t leave the phone charging until it reaches 100% either. When it reaches full load too, remove it from the load. Make good use of these tips to get an acceptable lifespan from your phone.

Let the phone rest once in a while
A phone that is on, even when not in use, still consumes power and therefore decreases battery life. Therefore, it is advisable to turn off your device from time to time to guarantee it more longevity. Before sleeping at night, you can turn off the phone to let the battery rest overnight.

Remember to activate airplane mode

When you are in an area where there is no network or your phone is working on wifi, your battery consumes much more than usual and quite quickly. To extend the life of your battery, the ideal is to put your phone in airplane mode.

Manage the brightness of your phone yourself.
In general, cell phones have a feature that regulates the brightness according to the environment in which you find yourself. Sure, it’s a useful feature, but it’s power-hungry. The best thing is to turn it off and regulate the brightness of your phone yourself.

Download an energy saving app
There are apps that can detect which features and apps are consuming the most power. This type of application also saves energy by cleaning the phone periodically.

Perform more “heavy and complex” tasks with your computer

It is true that a Smartphone can do everything, but in order to extend your battery life, you could perform certain tasks with a computer. So if you want to follow an online course or conference, open several pages at a time for research… the ideal would be to use a computer. Not only will this save your battery life, but it will also make you more comfortable with your tasks.

Avoid overheating your phone
Typically, you put the phone on charge at night before you go to bed so that it can be used all day the next day. This is a good practice for the user, but not for the phone battery which is gradually being destroyed. And for good reason, it takes about 3 hours to fully charge a mobile phone while all night, the phone spends more than 3 hours in charge, hence the overheating.

You should also take care not to expose your device to any major heat source such as the sun. Also be sure to avoid long gaming sessions on the phone and use it while it is charging. Finally as soon as you feel that the mobile phone is overheating, you stop everything and leave it at rest.

Prefer charging your phone to plug directly to a computer
Indeed, there is energy loss when using the port of a computer to charge the phone. The latter will then take longer to charge, which could cause the battery to overheat. However, any overheating of the battery is harmful to it, because it damages the battery and thus reduces its lifespan.

Remember to clean your mobile phone and update it regularly
Whether your apps are in use or not, you should know that they all use battery power. Deleting the apps you no longer use helps your phone’s battery save energy. Likewise, when you do not frequently update apps and the phone system, they require more energy to operate. You should therefore update regularly.

Your phone’s battery gradually loses its performance during use. However, if it is well maintained, it can work well for a long time.

Keep an eye on the state of your battery
When you scan the battery charge level from time to time, you will notice applications and functions that require more energy than others. Manufacturers, however, offer you quick ways to get this information on your mobile phone. To do this, if you have an Android phone, go to mobile settings, then click on battery and finally on battery usage. In case you have an iPhone instead of an Android, click on settings and then on the battery option.

The “energy saving” mode is more useful than it seems
If you didn’t know, this mode was developed with the main purpose of extending battery life. It does this by disabling certain features and apps of the phone that are not essential for the functioning of the phone. To activate this mode, it’s very simple, first go to settings (if it’s an iPhone) or in settings (if you have an Android), then in battery and finally you will press on activation of the saver of battery.

Close all apps and features you don’t use
When surfing on your mobile phone, you frequently quit one application for another without completely closing the previous one. While doing so, there are several background features and apps that always consume power, which decreases battery life. These applications that are not always used still consume energy. So clean your background regularly and disable any unused features at the moment.

In order to have a high-performance battery that is not harmful to the environment and human beings, several types of batteries have been created.

Lead batteries
These are batteries made up of a set of accumulators, they are the cheapest on the battery market today. They discharge quickly and are harmful to the environment due to the presence of lead.

Nickel-cadmium batteries
The essential components of this type of battery are nickel and cadmium electrodes. Coming from an old technology, they have a reduced lifespan and are now banned in the European Union due to the presence of cadmium.

Lithium ion batteries
There are two forms of lithium ion battery: lithium cobalt (LCO) and lithium manganese (LMO). They have a large storage capacity and low weight. They do not support overheating because they risk exploding. Their high performance makes them the batteries used for many devices.

Lithium polymer batteries
They are actually a form of lithium ion batteries, but are less dangerous because they contain gel. They also stand out for being much more expensive.

Nickel-metal hydride batteries
They now replace nickel-cadmium batteries and are safer since they are made without toxic metals. They are lighter and produce more energy than nickel-cadmium.

A phone battery is the home of renewable electrical energy that allows the cell phone to operate without being plugged into a power outlet. It is made like a battery and consists of two terminals, one positive called the cathode and the other negative called the anode. It also includes a semi-permeable separator and the electrolyte which is a conductive liquid.
