Compatible replacement for Razer Blade 15 Base

The KingSener RC30-0351 is a new lithium-ion battery built for the Razer Blade 15 Base 2020 and 2021 models. It matches the original form factor so installation requires no modification. The pack uses grade-A cells and a protected circuit board to deliver stable output. It is intended for owners who need a direct drop-in replacement.

60.8 Wh capacity with 4000 mAh at 15.2 V

The 60.8 Wh design capacity supplies enough energy for typical daily workloads and media playback. Runtime will vary with screen brightness, background tasks and power-profile settings. Heavy sustained loads such as gaming or rendering will deplete the charge faster than light office use. The battery reaches its limit when the notebook signals low power and initiates sleep.
