Finished in black, it provides a durable, factory-matching appearance and is intended to restore portability and runtime to systems that require a battery of this specification. The battery is engineered for stable output and includes built-in safety measures to reduce the risk of overheating and overcharging.

How to use

Power down the laptop, disconnect any external power source and remove the bottom cover or battery access panel according to the laptop manufacturer’s instructions. Replace the existing battery with the Lenovo 42T4845, ensuring proper alignment of contacts and secure mounting. Reinstall the cover and reconnect the mains adapter. Charge the battery fully before first use to allow the battery management system to calibrate and report accurate charge levels.

Usage recommendations
