How to properly remove the battery from an ASUS laptop: analysis of 12 popular models

Removing the battery from the laptop ASUS may be needed in a variety of situations: from a banal replacement of a swollen battery to complete disassembly of the device for repair. However, this process is not as simple as it seems at first glance. Modern models ZenBook, VivoBook or ROG often have non-removable batteries hidden under the back cover, and some older devices require careful disconnection of the cables. Errors here can lead not only to damage to the case, but also to a short circuit that can damage the motherboard.

In this article we will look at all possible ways to remove the battery for different lines ASUS, including models with easily removable and soldered batteries. You will learn what tools you will need, how to avoid common mistakes (for example, Damage to the power connector due to careless disconnection of the cable), and what to do if the battery is “stuck” to the case. We will pay special attention to safety measures - working with lithium-ion batteries always involves a risk of fire if handled incorrectly.

Preparing for Extraction: Tools and Safety Precautions

Before you start disassembling your laptop, make sure you have everything you need on hand. For most models ASUS you will need:

• 🔧 Screwdriver set (cross PH00, flat 1.5 mm, sometimes Torx T5 for models ROG)
• 🧲 Antistatic wrist strap or an alternative (for example, touching the metal case of the system unit)
• 📸 Smartphone for photography (to fix the location of cables and screws)
• 🧴 Plastic picks (for carefully prying off the cover without scratches)
• 🔋 Multimeter (optional, to check the voltage at the battery contacts)

Important: if you are working with a laptop that has been connected to the network, Be sure to turn off the power supply and remove the plug from the outlet. Even when turned off, the motherboard may still have enough voltage to damage components. For models with a non-removable battery (for example, ASUS ZenBook UX330) is also recommended hold down the power button for 30 seconds - this will discharge the capacitors.

⚠️ Attention: If the battery is swollen or deformed, do not try to pierce or bend it. Lithium-ion batteries may catch fire or explode if damaged. In this case, it is better to contact a service center.

Determine the type of battery: removable or built-in?

The first step is to understand what type of battery you are dealing with. U ASUS there are three main options:

1. Removable battery (found in older models, for example, ASUS K53E or X550C). Such batteries are secured with latches and can be easily removed without disassembling the case.
2. Built-in battery with cable (most modern laptops, including VivoBook S15 And ZenBook 14). Requires removing the back cover and disconnecting the connector.
3. Soldered battery (rare, but found in ultrabooks, for example, ASUS ZenBook Flip). You can't do without a soldering iron here.

To determine the battery type in your model, follow these steps:

1. Turn the laptop over and inspect the bottom cover. If you see separate hatch with battery icon - you have a removable battery.
2. Check the documentation or find your model on the website ASUS support. In the section User Guide There is usually information about the battery type.
3. If the cover is solid, most likely the battery is built-in. For accuracy, you can see the disassembly of your model at YouTube (search for "ASUS [model] battery replacement»).

Line of laptops	Battery type	Examples of models	Difficulty of extraction
ASUS ROG (Strix, Zephyrus)	Built-in (loop)	GL502, GU502, GA503	Medium (many screws, thermal paste)
ZenBook (UX, UXC)	Built-in (sometimes soldered)	UX330, UX430, UX534	High (thin body, fragile latches)
VivoBook (S, X, F)	Built-in (loop)	S14, X512, F512	Low (simple design)
TUF Gaming	Built-in (flex cable + additional screws)	FX505, FA506, A15	Medium (dense layout)
Old models (2012–2016)	Removable	K55, X550, R550	Minimum (2 latches)

Step-by-step instructions for removable batteries (older models)

If your laptop belongs to the rulers ASUS K, X or R (For example, K53SV or X550LD), most likely the battery is removable. The extraction process will take no more than 5 minutes:

Turn off the laptop and disconnect the power supply|

Turn the device over onto a flat surface|

Locate the two latches on the bottom cover (usually next to the battery icon)|

Slide the latches to the sides (on some models you need to press down)|

Gently pull the battery towards you without applying excessive force-->

If the battery does not respond, don't try to pull it out by force. It may be secured with an additional screw (found in models ASUS N56 or G75). In this case:

1. Look for a screw with a lock or battery icon (usually near the fasteners).
2. Unscrew it with a Phillips screwdriver PH0.
3. Try removing again by sliding the latches.

⚠️ Attention: On some models (for example, ASUS G750JX) removable battery has additional connector, which may oxidize over time. If you hear a cracking sound or see signs of corrosion when removing, clean the contacts with alcohol before installing a new battery.

After removal, inspect the battery contacts and socket in the laptop. If they turn black or have a green coating, this is a sign of oxidation. In this case:

• Clean the contacts with a cotton swab soaked in isopropyl alcohol.
• Let it dry for 10-15 minutes before installing a new battery.
• If the oxidation is severe, check the voltage with a multimeter - the socket may need to be replaced.

Removing the built-in battery: disassembling the case

For laptops with a non-removable battery (e.g. ASUS ZenBook UX425 or VivoBook S14 S433) the process is more complicated. This will require a full or partial analysis. Let's consider a universal algorithm:

Step 1: Removing the back cover

• Unscrew all screws on the bottom cover. In models ROG they may be hidden under the rubber feet - carefully pry them off.
• Use plastic pickto pry the cover evenly, starting from the corner. B ZenBook The latches are fragile - do not use force!
• If the cover does not budge, check that all the screws are unscrewed (sometimes one screw is hidden under a sticker).

Step 2: Disconnecting the Battery

• Find the battery - it usually takes up half the space under the cover and is connected through a wide cable.
• Pull gently black plastic latch connector up (in some models you must first lift the latch).
• If the cable is stuck, do not pull it - wet the contacts contact cleaner (For example, Kontakt 60) and wait 5 minutes.

Step 3: Removing the Battery

• The battery can be secured with screws (usually 2-4 pieces) or double-sided tape.
• If the screws are unscrewed, but the battery cannot be removed, pry it with a plastic card, moving from one edge to the other.
• In models ASUS TUF the battery is sometimes stuck - use hair dryer on low settingto soften the glue.

What to do if the battery cable is broken?

If you accidentally damage the contacts when disconnecting the cable, do not panic. In most cases, you can only replace the cable, and not the entire battery. To do this:

1. Order a new cable on AliExpress or at a service center (indicate the exact laptop model).

2. Carefully unsolder the old cable from the battery (if it is soldered) or disconnect it from the connector.

3. Solder the new cable, observing the polarity. For soldering, use a 30-40 W soldering iron and electronics flux.

⚠️ If you are not confident in your skills, it is better to contact a specialist - soldering errors can damage the battery.

⚠️ Attention: In laptops ASUS ROG (For example, Strix G15) the battery is sometimes connected to the motherboard via additional control connector. If, after disconnecting the main cable, the laptop does not turn on even from the power supply, check whether this connector remains connected (usually it is smaller and located nearby).

Features of battery removal in popular ASUS models

Each line of laptops ASUS has its own nuances. Let's look at the most common models:

ASUS ZenBook (UX330, UX430, UX534)

In ultrabooks ZenBook the battery is often glued to the case, and the cable is hidden under metal protection. To extract it:

1. Remove the back cover, starting from the corner near the hinge (the latches are weaker there).
2. Remove the 4 screws securing the metal plate above the battery.
3. Pry off the battery with a plastic card, heating the gluing areas with a hairdryer (temperature no higher than 60°C).

Important: B ZenBook UX425 The battery is divided into two parts - remove them one by one, starting with the smaller one.

ASUS ROG Strix/Zephyrus (G531, GU502, GA503)

In gaming laptops, the battery is often covered with an additional heat-dissipating film. Procedure:

1. Remove the back cover (at Zephyrus G14 it is secured with 12 screws).
2. Disconnect two cables: the main (power) and the control (can be designated as BAT_CON).
3. Remove the 6 battery mounting screws (in Strix G15 They are different lengths - remember the location!).

ASUS VivoBook (S14, S15, X512)

The simplest design among modern models. Enough:

1. Unscrew the 10 screws on the back cover (in VivoBook S14 S433 one screw is hidden under the rubber foot).
2. Disconnect the cable by pulling the black lock.
3. Remove the battery, which is held on with double-sided tape (in X512 hair dryer may be required).

What to do if the battery is stuck or swollen?

If the battery is deformed (swollen), remove it with extreme care. Lithium-ion batteries in this state are extremely dangerous. Follow this algorithm:

1. Do not use metal tools - even a small scratch can cause a short circuit.
2. If the battery is swollen but not leaking, try to remove it by prying plastic spatula around the edges.
3. If the battery is leaking (white or green traces of electrolyte are visible), don't touch it with your bare hands - use gloves. Electrolyte is toxic!
4. After removing, place the battery in non-flammable container (for example, a metal bucket with sand) and take it to a recycling point.

If the battery is so swollen that it cannot be removed from the socket:

• Try it cool it down (put the laptop in the freezer for 20 minutes - this will reduce the pressure).
• Use dental flossto cut through the double-sided tape (carefully pass the thread under the battery and pull in different directions).
• As a last resort, contact the service - some workshops have special tools for such cases.

⚠️ Attention: If, when removing a swollen battery, you feel strong chemical smell or noticed smoke, leave the premises immediately and ventilate it. These are signs that thermal runaway has begun—the battery can ignite within minutes.

Installing a new battery and checking its functionality

After removing the old battery, install the new one in reverse order. However, there are several critical points:

• 🔌 Check compatibility. The battery must have the same article number or rated voltage (For example, 11.4V for ASUS VivoBook S14). Using a battery with a different voltage will damage the power controller.
• 🔧 Tighten the screws in a crisscross patternto avoid body distortion (especially important for ZenBook with a thin aluminum body).
• 📋 Reset BIOS settings after replacement. To do this, when turning on the laptop, hold down F2, find the option Load Default Settings and save changes (F10).

After installing a new battery:

1. Connect the power supply and turn on the laptop.
2. Make sure the battery is recognized by the system (check in Device Manager → Batteries).
3. Execute calibration:
   1. Charge the battery to 100%.
   2. Disconnect the power supply and discharge until it turns off completely.
   3. Repeat the cycle 2-3 times.

If the laptop does not turn on after replacing the battery:

• Check if the battery cable is connected to the motherboard.
• Make sure that the connector is not damaged (sometimes the contacts become bent during installation).
• Try turning on the laptop without a battery (only from the power supply) - if it starts, the problem is in the new battery.

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when removing the battery. Here are the most common ones and ways to prevent them:

Error	Consequences	How to avoid
Using a metal screwdriver to pry off the cover	Scratches on the body, damage to the latches	Use plastic picks or guitar picks
Disconnecting the battery cable without locking the latch	Damage to the connector on the motherboard	First lift up the black clip, then carefully pull out the cable
Use of force when removing a stuck battery	Cable rupture, case damage	Use a hair dryer to soften the glue or dental floss
They forget to disconnect the additional control connector (in ROG)	The laptop does not turn on even from the power supply	Check all connectors marked as BAT or MBAT
Installing a battery with a different voltage	Failure of the power controller, fire	Check the article number and characteristics of the battery with the original one

Another typical problem is Laptop doesn't recognize new battery. The reasons may be as follows:

• 🔄 Reset EC/BIOS: Turn off the laptop, remove the battery and power supply, hold down the power button for 60 seconds.
• 🔌 Check the power supply: If it is faulty, the battery may not charge.
• 🛠️ Update BIOS: on the official website ASUS There may be firmware that fixes power issues.
