Product information

Description

Compatible BTI 45Wh 3-cell SB11L67331 battery for Lenovo ThinkBook 16 G7 (11.55V, 3900mAh, Li‑Ion, black) is a replacement lithium‑ion battery pack designed to restore portable power to ThinkBook 16 G7 IML/ARP models and several related Lenovo laptops. The pack contains three cells with a nominal voltage of 11.55 V and a rated capacity of 3900 mAh (45 Wh). The unit comes in a black casing and is supplied as a single battery intended for field replacement of a depleted or failing original battery.

Advantages

This BTI replacement battery offers a direct-fit form factor for compatible Lenovo ThinkBook models and uses Lithium‑Ion chemistry to provide a balance of energy density and cycle life. The 45 Wh capacity is suitable for typical mobile productivity tasks and can extend operational time compared with a heavily degraded original pack. Being a single-unit replacement in a matching colour and physical design, it simplifies maintenance and reduces downtime for users who need to continue working on the move.

Suitable for

  • Lenovo ThinkBook 16 G7 IML/ARP series
  • Lenovo K14 G2 / G3 and ThinkBook 14 G6 / 14 G7 compatible models listed by manufacturer
  • Mobile work, travel and remote productivity where extended battery life is required

Key specifications

  • Battery technology: Lithium‑Ion (Li‑Ion)
  • Capacity: 3900 mAh (45 Wh)
  • Nominal voltage: 11.55 V
  • Cell count: 3 cells
  • Colour: Black
  • Units included: 1 battery

How to use

Power the laptop down, disconnect any external power source, and follow the laptop manufacturer’s instructions for battery removal and installation. Handle the battery by its casing, avoid contact with connectors, and ensure the replacement aligns correctly with the laptop’s battery bay before securing. After installation, connect the AC adapter and allow the system to recognize the new pack; it may be advisable to charge the battery to full before first use. Refer to the Lenovo user manual for model‑specific removal steps, screw locations and safety warnings.

Usage recommendations

Store and use the battery in a dry, cool environment and avoid exposure to high temperatures or moisture. Use the laptop’s power management settings to optimize run time and charge cycles, and perform regular battery health checks through system diagnostics. Dispose of the old battery according to local electronic waste regulations or take it to an authorized recycling point.
