Purpose and fit

This replacement battery is built for the Razer Blade 15 Base 2021 and the RZ09-0369 family of chassis. It restores original runtime for owners whose factory pack has degraded. Buyers with other Blade models or newer revisions cannot use this pack.

Capacity and headroom

The 4-cell lithium-ion unit delivers 15.2V and 60.8WHR at 4000mAh, matching the OEM RC30-0351 specification. It supports typical daily workloads and media playback but will exhaust faster under sustained GPU-heavy loads or high screen brightness.

Installation and clearance

The pack fits the existing battery bay without adapters or cable changes. No BIOS update or driver install is required. It frees the user from tethered operation but does not add fast-charge capability beyond the laptop’s stock controller.

How can I verify the RC30-0351 is performing correctly after I install it?

After installation the OS should report 15.2V and a design capacity of 4000mAh, and the battery should charge to full without error messages.
