Q4: Will this battery work with the 2020 or 2022 Razer Blade Stealth 13?

• Included: Our kit includes the battery and often comes with the necessary basic tools, but check the product description to confirm.

Q10: How can I maximize the lifespan of my new Razer battery?

To get the most out of your battery:

• Use the “Balanced” power mode in Windows for daily use.

• Avoid letting the battery consistently drain to 0%. Try to keep it above 20%.

• If using the laptop plugged in for extended periods, consider using Razer Synapse settings (if available) to limit the maximum charge to 80%.

• Keep the laptop and its vents clean to prevent excessive heat, which is the primary enemy of battery health.
