Compatible battery for Razer Blade 15 2018

This replacement battery fits the Razer Blade 15 2018 model RZ09-0301 and several related part numbers. It uses a four-cell lithium-ion design rated at 15.4V and 5209mAh. The unit matches OEM part RC30-0248 for direct installation.

Verify model and part number before ordering

Confirm your laptop carries model number RZ09-0301 or one of the listed variants such as RZ09-02486 or RZ09-02888. Check that the original battery label shows part number RC30-0248. Ensure the voltage rating on your current pack reads 15.4V.

Steady discharge over long sessions

The four-cell lithium-ion chemistry delivers consistent voltage across extended workloads rather than a brief peak. Internal resistance remains stable during continuous discharge, so runtime stays predictable. Capacity holds through repeated charge cycles under normal thermal conditions.

Questions about this item

Does the RC30-0248 battery package include any installation tools or must they be purchased separately?

The listing describes only the 4-cell lithium-ion battery itself. No screwdrivers, pry tools or adhesive strips are mentioned, so plan to source those separately if your Razer Blade 15 2018 requires them.

My Razer Blade 15 2018 carries part number RZ09-02886; is the RC30-0248 the correct 15.4 V 5209 mAh replacement?

Yes. The RC30-0248 is listed as compatible with RZ09-02886 as well as RZ09-0301, RZ09-02486, RZ09-02888 and RZ09-03018, matching the original 15.4 V 5209 mAh specification.

What runtime improvement can I expect from the 5209 mAh capacity once the battery is installed in my Blade 15 2018?

The 5209 mAh rating restores the factory capacity, delivering the same 15.4 V output the original pack provided. Actual runtime will match the laptop's original battery life when new, varying with workload and screen brightness.
