## Long description

Rechargeable laptop battery Lenovo 57Wh 3-cell Li‑Polymer designed as a direct replacement for compatible Lenovo notebook models. This 57 watt‑hour battery uses three lithium‑polymer cells to provide a balance between capacity and compact design, intended to restore or extend laptop runtime for mobile work, travel, and everyday use when the original battery no longer holds charge.
Advantages
The battery offers a 57Wh capacity in a slim 3‑cell Li‑Polymer format that helps maintain a lightweight profile while supplying sufficient energy for typical office, web browsing, and media playback tasks. As a replacement unit, it is compatible with systems that accept the same physical and electrical specifications and is intended to provide stable voltage and discharge characteristics comparable to OEM performance. The Li‑Polymer chemistry reduces risk of swelling compared with older cell types and allows for compact packaging.
Suitable for
 Replacing a degraded or non‑functional original Lenovo laptop battery with the same size and connector type
 Extending runtime for mobile office work, remote meetings, and web browsing
 Travel use where access to mains charging is intermittent
 Everyday use for students and professionals who need predictable battery life
Key specifications
 Battery type: Lithium‑polymer (Li‑Po)
 Nominal capacity: 57 Wh
 Cell count: 3 cells

 Typical applications: notebook runtime extension and OEM replacement
How to use
Power down the laptop and disconnect it from any external power sources before beginning replacement. Remove the service cover or battery access panel and carefully unplug and extract the depleted battery following the laptop manufacturer’s disassembly guidance. Install the replacement battery by seating it in the compartment and reconnecting the battery cable; reassemble the cover and reconnect external power. After first installation, charge the battery fully before normal use to allow the battery management system to calibrate state‑of‑charge reporting. Always use manufacturer‑recommended screws and avoid forcing connectors.
Usage recommendations
Store and operate the battery at recommended ambient temperatures (typically between 5°C and 35°C for charging and 0°C–45°C for discharging) and avoid prolonged exposure to high heat. If the laptop will not be used for extended periods, store the battery at around 40%–60% charge in a cool, dry place. Dispose of the depleted battery according to local electronic waste regulations and do not puncture or incinerate the pack.
