Replacement battery for Asus Zephyrus G16

This new lithium-ion pack replaces part numbers C41N2303 and 0B200-04450000. It fits the Rog Zephyrus G16 GU605MV and the wider GU605 series including 2024 and 2025 models. The black cell is built for owners who need a direct swap without adapter cables.

15.48V lithium-ion voltage constraint

The fixed 15.48V output matches the original specification exactly. Laptop charging circuits expect this voltage window; a higher or lower pack will not communicate with the embedded controller. No firmware update or BIOS change can alter that electrical boundary.

90Wh capacity for full-day workloads

At 90Wh the battery supports typical productivity and media playback through a standard workday. Heavy GPU loads such as sustained rendering or gaming will drain the pack faster, requiring a recharge before the next session. Users who need multi-day autonomy should consider a higher-capacity alternative if one exists for this chassis.
