ZTHY C41N1727 Laptop Battery 15.4V 55Wh for Asus Zephyrus

ZTHY C41N1727 is a direct-fit 15.4V, 55Wh Li-Polymer replacement battery designed to restore run-time and compatibility for select Asus ROG Zephyrus M and GU501 laptop models.

If your Asus Zephyrus M or a compatible GU501 series laptop is showing shortened battery life, unexpected shutdowns, or won’t hold charge, this replacement battery provides a factory-style swap. The C41N1727 unit is a 4-cell Li-Polymer pack built to match the original power and dimensions and uses the same form factor and connector layout as the OEM for an easy installation.

How will this battery affect my laptop’s daily run-time?

Installing the ZTHY C41N1727 returns capacity to the rated 55Wh, which typically restores the original on-battery operation you experienced when the machine was new. Real-world run-time depends on system load, display brightness, and background apps, but the higher usable capacity reduces the frequency of charging cycles.

What should I do if the new battery isn’t recognized right away?

If your laptop does not immediately detect the replacement, follow a simple initialization routine: reseat the connection, perform a partial discharge to about 10–20%, then fully charge and cycle the battery several times. This process helps the internal monitoring electronics calibrate and report accurate capacity.

• Ensure connector is fully seated and screws align with mounts
• If unrecognized, discharge to 10–20% (avoid 0%), then charge fully
• Perform 3–4 charge/discharge cycles to improve battery reporting

It’s suitable for DIY-savvy users comfortable opening laptops, technicians replacing batteries for clients, and anyone seeking an OEM-spec capacity restore without upgrading the system. Always verify your laptop’s model and battery part number before purchase and follow safe handling and installation practices.
