Product information

Description

Replacement laptop battery Lenovo model 5B11B36309 is a 3-cell battery with a nominal voltage of 11.4 V designed to restore mobile runtime for compatible Lenovo notebooks. It serves as a direct-compatible power source when matched to a notebook that accepts the same physical connector and voltage, enabling battery-powered use for office tasks, web browsing and travel. The pack is intended to match original-spec voltage and basic form factor to deliver predictable operation when installed in a supported laptop.

Advantages

This 3-cell 11.4 V battery provides a compact, lightweight power option that replaces a depleted internal pack without requiring modifications. It offers nominal voltage matching to original equipment, straightforward installation in compatible systems, and is designed to resume portable operation to support everyday productivity. The battery is suitable for scenarios where restoring runtime quickly and reliably is the primary need.

Suitable for

  • Office productivity and document editing on compatible Lenovo laptops
  • Web browsing, email and lightweight multimedia while away from AC power
  • Travel and mobile use where a compact replacement battery is required
  • Replacing a worn or non-functioning original battery in compatible models

Key specifications

  • Cell count: 3-cell lithium battery
  • Nominal voltage: 11.4 V
  • Form factor: internal replacement pack sized for compatible notebook bays
  • Connector type: notebook-specific multi-pin connector (matches compatible Lenovo models)
  • Primary use: portable power for laptops

How to use

Power down the laptop, disconnect the AC adapter and remove the old battery following the laptop manufacturer's service instructions. Align the replacement pack's connector with the laptop socket and insert it until it seats securely, ensuring any locking catches engage. Reconnect AC power if required for initial charging and allow the battery to charge to full capacity before regular mobile use. Verify battery recognition and charging status through the operating system battery indicator or built-in firmware tools.

Usage recommendations

Use this battery in Lenovo notebook models that explicitly accept the same voltage and connector style. For safety and optimal performance, avoid exposing the battery to extreme temperatures, physical shock, or liquid. Dispose of the depleted battery at an approved recycling facility and follow local regulations for battery handling. If in doubt about compatibility, consult the laptop's service manual or a qualified technician before installation.
