How does performance compare to the original battery?

The TREE.NB pack uses Grade A cells and factory testing to replicate the original capacity and voltage, delivering comparable battery life and charging behavior. Built-in circuit protection helps prevent overcharge and short circuits, so daily performance aligns closely with the OEM unit when installed correctly.

• Capacity: 65Wh at 15.4V, matching original power specifications.
• Cell count: 6-cell configuration for the same energy density and physical fit.
• Cycle durability: rated up to about 500 recharge cycles under normal conditions.

What should I expect during installation and setup?

Installation follows standard Razer Blade battery replacement steps—power down, remove the back cover, disconnect the old battery, and attach the new pack. No special drivers are required; the system should recognize the replacement after reconnection and boot, though performing a battery calibration cycle once installed is recommended for accurate charge reporting.

• Mounting: same screw locations and connector orientation as original packs.
• Safety: integrated protection circuit and factory testing reduce installation risk.
• Post-install: calibrate by charging to 100% then fully discharging once to reset charge reporting.
