Replacement battery for Razer Blade Advanced 15

This 15.4V 80Wh lithium-ion unit replaces the original Rc30-0248 cell in Razer Blade Advanced 15 models from 2018 through 2021. It fits the Rz09-02385, Rz09-02386, Rz09-0288, Rz09-0301, Rz09-03137 and Rz09-03138 series, including RTX 2060, 2070 and 2080 configurations. The pack is new and carries CE, FCC and RoHS safety certifications.

Straightforward internal swap with common pitfalls

Installation requires opening the chassis and disconnecting the factory battery before fitting the replacement. The connector matches the original 4Icp4/55/162 pinout, so no adapter is needed. The main risks are damaging the fragile ribbon cables around the trackpad or forgetting to disable the built-in battery in the BIOS before starting work.

80Wh capacity for typical workloads

The 80Wh rating restores the runtime the laptop shipped with, handling several hours of office tasks or media playback on a full charge. Heavy GPU loads such as sustained gaming or rendering will drain the pack faster, and the single-cell design means capacity drops noticeably after a few hundred cycles. Buyers needing all-day autonomy away from a wall outlet should consider a higher-capacity alternative if one exists for this chassis.

Questions about this item

How can I verify the 15.4V 80Wh battery is working correctly after installation?

The laptop should power on without the charger, show the battery charging in the OS, and report a design capacity near 80Wh in the battery health section.

What comes in the box and is anything else needed for the Rc30-0248 replacement?

The package contains one 15.4V 80Wh Li-Ion battery; no extra cables, tools or adapters are required for installation.

Which compatible part number should I match — Rc30-0248, Rz09-02386 or 4Icp4/55/162?

All three identifiers refer to the same 15.4V 80Wh cell; match any one of them to the label on your original battery.
