Direct replacement for Razer Blade 15 2020

This 65WH lithium-ion battery fits the Razer Blade 15 2020 and the listed RZ09-0328, RZ09-03304x, RZ09-03305x and RZ09-0330x models. It delivers 15.4V and 4221mAh in a black housing. Owners of those specific laptops can swap the original pack without modification.

Upgrade from a depleted or swollen original pack

When the factory cell no longer holds charge or shows physical swelling, this new unit restores full runtime. The jump is worth it the moment the old battery forces you to stay tethered to an outlet or triggers unexpected shutdowns under load.

65WH capacity for typical work sessions

At 4221mAh the pack comfortably powers web browsing, document editing and video playback for several hours. Heavy GPU workloads or sustained high brightness will drain it faster, so users running demanding creative tasks should keep the charger nearby.

Questions about this item

Will the RC30-0328 battery fit my Razer Blade 15 RZ09-03304x chassis?

Yes, the RC30-0328 is built to the same 4ICP5/46/108 form factor used in the Razer Blade 15 2020 series including RZ09-03304x, RZ09-03305x and RZ09-0330x models.

What is the correct order for connecting the battery cable during installation?

Insert the battery into the bay, align the screw holes, secure the screws, then plug the connector into the motherboard header — connecting the cable before the battery is seated can bend the pins.

How long will the 4221mAh lithium-ion cells hold a useful charge before I need a new pack?

Lithium-ion packs typically deliver several hundred full charge cycles before runtime falls noticeably; the 65WH rating and 15.4V output remain stable through normal daily use.
