How to check compatibility
Finding your exact ASUS model number is crucial for battery compatibility. For ASUS laptops, you can locate this information in several ways:
Physical Inspection: Check the bottom casing of your laptop for a sticker containing the model number. For ASUS VivoBook and PU series, this is typically near the battery compartment or on the main chassis.
System Information: Press Windows Key + R, type “msinfo32” and look for “System Model” in the System Information window. This method works for all ASUS models including the 0B200 series and X50PW9C.
Command Prompt: Open Command Prompt and type “wmic csproduct get name” to display your exact model.
ASUS Support Centre: Visit the official ASUS support website and use their compatibility checker tool. Enter your serial number or model to verify battery requirements.
Remember that ASUS often uses multiple model numbers for the same hardware configuration, so cross-reference with our compatibility table above.
When to replace
Timing your battery replacement correctly ensures optimal performance and safety. Consider replacement when:
- Battery capacity drops below 60% of original
- Your laptop lasts less than 2 hours on battery
- You experience frequent unexpected shutdowns
- The battery shows physical swelling or damage
- Your device is 2-3 years old with regular use
For ASUS laptops in the compatible models list, the C31-X502 44Wh battery provides the exact specifications required by your device’s power management system.
Installation guide
Replacing your ASUS battery is straightforward with proper preparation. Before beginning, ensure you have a clean, static-free workspace and the correct tools.
Step 1: Safety First
Turn off your laptop completely and disconnect the AC adapter. Ground yourself to prevent static discharge that could damage internal components.
Step 2: Access the Battery Compartment
For ASUS VivoBook S500C/S500CA and X502 series: Flip the laptop over and locate the battery release latches. These models typically have external battery compartments.
For ASUS PU500/P500CA and 0B200 series: You may need to remove the bottom panel. Use a plastic spudger to carefully pry open the casing, starting from the corners.
Step 3: Remove Old Battery
Disconnect the battery connector from the motherboard by gently pulling the connector, not the wires. Release any securing clips or screws holding the battery in place.
Step 4: Install New Battery
Position the new C31-X502 44Wh battery in the compartment, ensuring proper orientation. Reconnect the battery connector firmly and secure with any clips or screws.
Step 5: Initial Charge
Before first use, connect your AC adapter and charge the battery completely. This calibrates the battery monitoring system for accurate readings.
Usage & care tips
Maximise your new battery’s lifespan with these expert tips:
- Charge Cycles: Lithium-ion batteries perform best with partial discharges rather than full cycles. Avoid letting your battery drain completely.
- Temperature Management: Keep your ASUS laptop between 15°C and 25°C for optimal battery health. Extreme temperatures accelerate degradation.
- Storage: If storing your laptop long-term, charge the battery to 50-60% and store in a cool, dry place.
- Power Settings: Use ASUS Power4Gear Hybrid or Windows power plans to optimise battery usage based on your activities.
- Regular Use: Even when primarily used plugged in, allow your battery to discharge to 20% at least once per month to maintain calibration.
Safety & recycling in AU/NZ
Battery safety and proper disposal are regulated in Australia and New Zealand. The C31-X502 44Wh battery meets all Australian/New Zealand safety standards.
Safety Precautions:
- Never attempt to disassemble or modify the battery
- Avoid exposing to temperatures above 45°C
- Do not puncture or crush the battery
- Keep away from water and moisture
- Use only ASUS-approved chargers
Recycling Information: In Australia, take used batteries to any Batteryback collection point. In New Zealand, use the Recycle Me programme. Both countries prohibit landfill disposal of lithium-ion batteries due to fire risk and environmental concerns. Many electronics retailers offer free battery recycling services.
