How to check compatibility
Finding your exact ASUS model information is crucial for battery compatibility. For ASUS ZenBook UX series laptops, you have several options:
Method 1: Check the bottom label – Turn your laptop over and look for the model number printed on the sticker. It should clearly state “UX310UA”, “UX410UQ”, or similar.
Method 2: Use System Information – Press Windows Key + R, type “msinfo32”, and look for “System Model” in the System Information window.
Method 3: ASUS Official Support – Visit the ASUS Australia support website and use their product identification tool by entering your serial number.
Method 4: Check Original Battery – If you still have access to your current battery, remove it carefully and check the part number printed on it.
The B31N1535 battery is specifically designed for the ultra-slim ZenBook UX series, featuring the exact dimensions and connector type required for these models. Always verify your model matches our compatibility list above before purchasing.
When to replace your ASUS battery
Most ASUS ZenBook batteries last between 2-4 years with normal use. Consider replacement when:
- Your battery health shows less than 60% of original capacity
- You experience sudden shutdowns even with charge remaining
- The battery takes significantly longer to charge
- You notice physical swelling or deformation
- Your laptop can’t complete important tasks on battery power
For Australian and New Zealand customers, it’s particularly important to consider replacement before the summer months when higher temperatures can accelerate battery degradation.
Installation guide
Replacing the battery in your ASUS ZenBook UX series is straightforward with the right tools and precautions:
Tools needed: Phillips #00 screwdriver, plastic spudger, anti-static wrist strap (recommended)
Step 1: Safety first – Shut down your laptop completely and disconnect the AC adapter. Ground yourself to prevent static discharge.
Step 2: Access the battery compartment – Remove the 10-12 screws from the bottom case using your Phillips screwdriver. Gently pry open the bottom cover using a plastic spudger.
Step 3: Disconnect the old battery – Locate the battery connector near the centre of the motherboard. Carefully disconnect the battery cable by pulling the connector straight out.
Step 4: Remove old battery – Unscrew the 4-6 screws securing the battery to the chassis. Lift the battery out carefully.
Step 5: Install new battery – Place your new B31N1535 battery in position, secure with screws, and reconnect the battery cable firmly.
Step 6: Reassemble and test – Replace the bottom cover, screw it back in, and power on your laptop. Allow the battery to charge fully before first use.
Note: Some UX models may have slightly different screw patterns, so take photos during disassembly for reference.
Usage & care tips for longer battery life
Extend the life of your new ASUS battery with these proven techniques:
- Avoid extreme temperatures – Don’t leave your laptop in cars during Australian summers where temperatures can exceed 50°C
- Optimal charging – Keep battery between 20-80% for daily use; avoid constant 100% charging
- Calibrate monthly – Fully discharge then recharge to 100% to maintain accurate battery reporting
- Storage advice – If storing long-term, charge to 50% and store in cool, dry place around 15-25°C
- Power settings – Use ASUS Battery Health Charging software to optimise charging patterns
