Which Razer Blade 15 models will this battery work with?

This battery is built to match the Razer Blade 15 Base editions released in 2020 and 2021 that require a 15.4V, 65Wh pack. It supports multiple OEM part numbers and trims used across base-model Core i7 systems with mobile NVIDIA GPUs.

How long will one charge last and what about cycle life?

• Nominal capacity: 65Wh (about 4221mAh at 15.4V) for balanced runtime.
• Up to ~500 cycles expected with proper charging and cooling practices.
• Performance varies with screen brightness, apps running, and GPU load.
