With a 4400mAh rated capacity, this extra digital battery restores portable runtime and enables continued use of the laptop away from mains power. The design matches form, voltage and connector placement of the supported Lenovo models to ensure proper fit and reliable electrical connection.

Key specifications

  • Intended device type: notebook / laptop
  • Compatibility: designed for specific Lenovo notebook models requiring the 40Y6999 form factor
  • Physical design: replacement pack matching original connector and mounting points

How to use

Before installation, power off the laptop and disconnect the external power adapter. Remove the original battery following the laptop manufacturer's instructions, taking care to avoid contact with metal objects and to discharge static electricity from your hands. Fit the extra digital replacement battery into the compartment, ensuring the connector aligns correctly, then secure any latches or screws as required. Reconnect the mains adapter and allow the battery to charge fully before first heavy use to calibrate charge reporting.

Usage recommendations

If the battery is stored before use, keep it in a cool, dry place with partial charge (around 40–60%). Avoid exposing the battery to high temperatures or moisture. Use the laptop's power management settings to optimize lifespan: avoid deep discharges when possible, and store the device with moderate charge if it will not be used for extended periods.
