Where is the battery located in an ASUS laptop: location in 15+ models

Why is it important to know where the battery is located in ASUS

Have you noticed that the laptop ASUS began to discharge in an hour instead of the usual 5–6? Or does the device suddenly turn off when unplugged, although the indicator shows 30% charge? In 80% of cases, a worn-out battery is to blame - and replacing it can give your laptop a second life. But before you run to the service center or order a new battery, you need accurately determine its location.

U ASUS there is no single standard: in some models the battery is hidden under the back cover, in others it is built into the case and requires complete disassembly, and in others (for example, ASUS ROG Zephyrus) it cannot be replaced at all without a specialized tool. This article will help you avoid common mistakes: from damaging cables to buying an incompatible battery. We'll sort it out 15+ popular episodes - from budget VivoBook to gaming ROG Strix, — and we’ll also tell you how to check the battery status without disassembly.

Three types of battery placement in laptops ASUS

Laptop design ASUS depends on the year of manufacture, series and even the specific modification. All options can be divided into three categories:

• 🔋 Removable battery — secured with latches under the back cover (typical for models before 2018 and some budget lines).
• 🔧 Built-in but accessible - soldered to the motherboard, but the cover can be removed without disassembling the entire case (for example, ASUS ZenBook UX330).
• 🛠️ Fixed (integrated) - requires complete disassembly, including disconnecting the keyboard and cables (relevant for ultrabooks ZenBook Pro and gaming ROG).

To understand which category your laptop belongs to, just look at the bottom cover. If it has:

• 🔄 Separate section with latches (usually in the center or closer to the screen hinge) - the battery is removable.
• 🔩 Lots of screws (10+) and there are no visible connectors - the battery is built-in.
• 🚫 The inscription “No serviceable parts inside” - disassembly may void the warranty (typical for ASUS ExpertBook).

Where to look for a battery in popular series ASUS

Below is a table with the location of batteries in the most common models. If your series is not on the list, focus on year of manufacture And housing type (ultrabook, gaming, transformer).

Laptop series	Models (examples)	Battery location	Replacement Difficulty (1–5)
ZenBook	UX305, UX330, UX430, UX534	Under the back cover, glued to the body	3
VivoBook	S14, S15, X512, X570	Removable (latches) or under cover (screws)	1–2
ROG Strix	G531, G731, Scar III, Hero III	Under a separate section of the cover (screws + latches)	2
ROG Zephyrus	G14, G15, S17	Integrated into the body, requires disassembly	5
TUF Gaming	FX505, FX705, A15, A17	Under the back cover, secured with screws	2–3

Important! In laptops ASUS 2020 and newer (for example, ZenBook Duo or ROG Flow) the battery is often divided into two modules: main and additional. The second one can be under the keyboard or even at the base of the screen (as in ASUS ProArt StudioBook).

⚠️ Attention: In models ASUS Chromebook (For example, C423, C425) the battery is soldered to the motherboard and is officially not replaceable. Trying to disconnect it without experience may result in damage to the power controller.

Step-by-step instructions: how to find a battery in ASUS VivoBook And ZenBook

Let's look at the two most popular scenarios: removable battery (for example VivoBook X512) and built-in (for example ZenBook UX425).

Scenario 1: Removable battery (VivoBook, TUF Gaming FX505)

You will need:

• 🔧 Plastic spatula (or pick)
• ⚡ Phillips screwdriver (PH0 or PH1)
• 🧲 Magnetic screw mat (optional)

Steps:

1. Unplug your laptop and hold the power button for 15 secondsto discharge the capacitors.
2. Turn the device over and find the section with battery icon (usually next to the "Battery" label).
3. Unscrew the screws (if any) and carefully pry the cover off with a spatula. B VivoBook it is held on by 2-3 latches.
4. Disconnect the battery connector from the motherboard (pull the plastic tab, not for the wires!).
5. Remove the battery by pulling the special loop or prying it from the side.

Scenario 2: Built-in battery (ZenBook, ROG Zephyrus)

Here the process is more complicated - it will require complete disassembly. For ZenBook UX425:

1. Remove all 12 screws from the back cover (note: 4 of them may be hidden under the rubber feet!).
2. Heat the edges of the lid with a hairdryer (temperature 60–70°C) to soften the glue.
3. Carefully pry off the cover using plastic spatula, starting from the corner near the power connector.
4. Disconnect the battery cable (in ZenBook it is usually located under metal protection).
5. Unscrew the 4 screws securing the battery and carefully separate it from the case (it may be glued!).

How to check the condition of the battery without disassembling

Before you climb inside the laptop, make sure that the problem is with the battery. Here 3 diagnostic methods:

Method 1: Via MyASUS (official software)

1. Install the utility MyASUS with official website.
2. Go to section Support → Battery Health Charging.
3. Look at the parameters:
   • 🔋 Full Charge Capacity — current capacity (should be close to the nameplate).
   • 📉 Wear Level — wear (more than 50% means it’s time to change the battery).

Method 2: Via Command line (Windows)

Open CMD as administrator and enter:

powercfg /batteryreport /output "C:\battery_report.html"

Open the generated file battery_report.html and find the lines:

• Design Capacity - factory capacity.
• Full Charge Capacity — current capacity.
• Cycle Count — number of charging cycles (more than 500–1000 means critical wear).

Method 3: Visual diagnosis

Signs that the battery needs to be replaced urgently:

• 🔥Laptop gets hot in the touchpad area even without load (the battery is swollen!).
• ⚡ Charge drops from 100% to 0% per less than 30 minutes.
• 🔌 Laptop works only from the network, despite the charge readings.

⚠️ Attention: If the battery swollen (the case lid is raised, the keyboard is “playing”), immediately unplug your laptop and do not use it until the battery is replaced! Lithium-ion cells in this state can ignite.

Common mistakes when finding and replacing a battery

Even experienced users sometimes make mistakes that lead to laptop damage or purchasing an incompatible battery. That's what can't do:

• 🛑 Ignore battery model. For example, for ASUS TUF A15 (FA506) batteries fit C31N1527 or C41N1527but they not interchangeable with ROG Strix G531!
• 🔌 Disconnect the battery cable when the laptop is turned on. This may burn out the power controller.
• 🔧 Use metal tools to remove the glued battery. The risk of puncture of elements is 90%.
• 📦 Buy a battery from a photo. One model ASUS there may be 2-3 battery options (for example, VivoBook S14 with a capacity of 42Wh and 50Wh).

Another typical problem is mismatch of connectors. For example, in ASUS ROG Strix G731 a 6-pin connector is used, and TUF A15 - 4-pin. If you buy the wrong battery, you simply won’t be able to connect it.

How can I find out the exact battery model?

Open the back cover of the laptop and look for the sticker on the battery. It indicates:

- Model (for example, A32-N55 for ZenBook UX330).

- Capacity (in Wh or mAh).

- Date of manufacture (if the battery is more than 3 years old, it is better to replace it even with normal capacity).

Where to buy an original battery for ASUS and how not to run into a fake

The laptop battery market is flooded with fakes that can:

2. The original battery weighs 10–15% more fakes (due to quality elements).
3. On the original connector there is protective film or rubber gasket.
4. Counterfeits are often sold without box and documentation.
