Common signs you need a replacement

How to check compatibility

Before purchasing any replacement battery, verify your exact laptop model. For ASUS TUF Gaming laptops, you can find the model number on the bottom case sticker, typically near the battery compartment. The sticker will show the full model designation like “FX505GD” or “TUF Gaming FX505DT”. You can also check in Windows by pressing Windows Key + R, typing “msinfo32”, and looking under System Model. Cross-reference your model with our compatibility table above. ASUS Australia’s official support website also has compatibility checkers, but our comprehensive list covers all verified compatible models for the B31N1726 battery.

When to replace

Replace your ASUS battery when you notice consistent performance issues. For gaming laptops, battery health directly impacts performance during intensive sessions. If your battery health shows less than 60% capacity in diagnostic tools, or if you experience sudden shutdowns during gaming, it’s time for replacement. Australian summers can accelerate battery degradation, so monitor your battery health more frequently during hotter months.

Installation guide

Replacing the B31N1726 battery in compatible ASUS TUF Gaming models requires careful handling. First, power down completely and disconnect the charger. Flip the laptop over and locate the battery compartment. Most TUF Gaming models have accessible battery screws – typically Phillips #00 size. Remove all screws securing the bottom panel, then gently pry the panel starting from the corners. Locate the battery connector near the centre of the motherboard – it’s usually a white or black plug. Carefully disconnect by pulling straight up, not sideways. Remove the old battery and place the newB31N1726 battery, ensuring the connector aligns properly. Reconnect the battery, replace the bottom panel, and power on. The system should recognise the new battery automatically. For specific models like the FX505 series, you may need to reset the BIOS by disconnecting both power and battery for 30 seconds before installation.

Usage & care tips

Maximise your new ASUS battery’s lifespan with proper care. Avoid constant 100% charging – for gaming laptops used primarily plugged in, set the battery health setting in ASUS Armoury Crate to Maximum Lifespan mode, which limits charging to 60%. Don’t expose your laptop to temperatures above 45°C, common in Australian cars during summer. Perform full discharge cycles monthly to calibrate the battery meter. Store between 15-25°C when not in use.

Safety & recycling in AU/NZ

Battery safety is paramount. Never attempt to open or puncture lithium-ion batteries. If your old battery shows swelling, handle with care and recycle immediately. In Australia, most electronics retailers accept battery recycling through the B-cycle program. In New Zealand, check with your local council for battery recycling facilities. Never dispose of batteries in household rubbish – they pose fire risks in landfill.
