How to Install Your New C41N1802 Battery?

Replacing the internal battery in the ROG Zephyrus S GX701 involves handling the unique AAS (Active Aerodynamic System) cooling bottom.

C41N1802 Battery Step-by-Step Installation Guide

1. Open the Bottom Cover:
   Power off the laptop and remove the screws on the bottom. Note: Some ROG Zephyrus models have screws hidden under the AAS flap. Carefully lift the flap to access them.
2. Lift the Internal Shield:
   Once the bottom cover is off, you may need to move aside some internal brackets or cooling components, depending on your specific sub-model.
3. Disconnect the Battery Cable:
   The C41N1802 has a wide multi-pin connector. Use a plastic tool to gently slide the metal locking clip (if present) and pull the connector vertically or horizontally away from the motherboard.
4. Remove the Old Battery:
   Remove the Phillips screws holding the battery in place. Carefully lift the old battery out.
5. Install the New HTJ Battery:
   Place the new battery into the bay, aligning it with the screw holes. Secure the screws and reconnect the battery cable firmly.
6. Reassemble and Calibrate:
   Replace the covers and screws. Charge the battery to 100%, keep it charging for 2 hours, then discharge to 5% to calibrate the power management system.

💡 Pro Tip:

While the Zephyrus S is open, clean the dual fans. Since this laptop series relies on high airflow, clean fans will keep your new battery and the overall system much healthier.

Q: How to tell the difference between C41N1802 and C41N1805?

A: Check the capacity. The C41N1802 (76Wh) is longer and used in 17-inch GX701 models. The C41N1805 (50Wh) is shorter and used in 15-inch GX531 models.

Laptop Maintenance Tips:

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run a battery down to 0%, as this would shorten its usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. When fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
