Razer Blade 15 2018 replacement battery

This 15.4V lithium-ion pack replaces the original RC30-0248 cell in compatible Razer Blade 15 2018 models. It delivers 80WHR and 5209mAh across four cells for restored runtime. Owners of listed RZ09 part numbers can use it as a direct swap.

Installation fits the existing bay without

The battery sits in the factory location and connects to the stock cable. Removing the bottom cover requires a Torx driver and careful ribbon-cable handling. The most common issue is forgetting to disconnect the main battery cable before lifting the old pack, which can trigger a short.

80WHR capacity matches the OEM specification

At 15.4V and 5209mAh the pack provides the same energy budget as the original unit. It powers typical workloads for the duration Razer specified. Heavy GPU loads or sustained maximum brightness will drain it faster, just as the factory battery did.

Questions about this item

After installing the RC30-0248 in my Razer Blade 15 2018, how can I confirm the 15.4 V 80 Wh battery is functioning correctly?

The system should recognise the GreenTech battery immediately, show a full charge capacity near 5209 mAh in the OS power report, and run without unexpected shutdowns during normal use.

What comes in the box with the RC30-0248 and is any extra hardware needed for the RZ09-02386 swap?

Only the 4-cell lithium-ion battery is supplied; no tools, screws or cables are included, so reuse the existing fasteners from the old pack.

The listing mentions several RZ09 model codes — which one matches my Blade 15 2018 unit?

All listed codes from RZ09-02386 through RZ09-03018 are compatible; match the sticker on your laptop bottom case to any of those numbers to confirm fit.
