Lenovo Battery Safety Data Sheets (SDS) – Official Documentation Sources

UMC Reference Documentation
Last updated: 23 February 2026

United Metrolite Central (UMC) recognizes Safety Data Sheets (SDS) as authoritative safety documentation for lithium-based batteries used in Lenovo laptops, including but not limited to ThinkPad, Legion, and IdeaPad product lines.

Lenovo laptop batteries are classified as Lithium-Ion or Lithium-Polymer battery assemblies and are manufactured using cells sourced from multiple Lenovo-approved vendors. As a result, battery chemistry characteristics, internal construction, and SDS documentation may vary depending on the specific battery part number and vendor.

Authoritative SDS Source (Lenovo)

UMC references Lenovo’s official Regulatory Compliance portal as the primary source for battery SDS and transport safety documentation:

  • Lenovo Regulatory Compliance – Battery Safety Data Sheets (SDS) & UN 38.3 Test Summaries

This Lenovo-maintained repository provides:

  • Official Safety Data Sheets (SDS)

  • UN 38.3 lithium battery transport test summaries

  • Battery identification tools for matching part numbers to documentation

UMC does not reproduce or modify SDS content and relies exclusively on manufacturer-issued documents for chemical safety guidance.

UMC-Recommended SDS Identification Procedure

To ensure accuracy and traceability, UMC recommends locating SDS documents using the battery part number, rather than relying solely on the laptop model.

Recommended process:

  1. Identify the battery ASM / FRU part number from:

    • the physical battery label, or

    • Lenovo Support systems using the device serial number

  2. Use Lenovo’s Battery Information Finder (provided within the Regulatory Compliance portal) to match the part number to:

    • the applicable SDS document

    • the corresponding UN 38.3 transport summary

  3. Retain the SDS reference as part of the device’s safety and service documentation.

This approach accounts for Lenovo’s use of multiple approved battery vendors and ensures correct safety interpretation.

How to Find the Correct SDS for a Lenovo Battery

To ensure accuracy, SDS documents should be matched to the specific battery part number, not only the laptop model.

Recommended steps:

  1. Identify the battery ASM / FRU part number from:

    • the battery label, or

    • Lenovo Support (using the device serial number)

  2. Use Lenovo’s Battery Information Finder (provided on the SDS portal) to map the part number to:

    • the correct SDS document

    • the corresponding UN 38.3 test summary

  3. Download the SDS PDF issued by Lenovo or the approved cell manufacturer.

Lenovo explicitly notes that batteries may be sourced from multiple approved vendors, and SDS documents may differ accordingly while remaining compliant with Lenovo specifications .

Examples of Lenovo Battery SDS Documents

Lenovo publishes SDS files for lithium-ion battery packs manufactured by different approved vendors. Examples include:

These SDS documents describe:

  • battery chemistry classification

  • electrical and thermal hazard characteristics

  • safe handling and storage instructions

  • emergency and fire-fighting measures

  • disposal and recycling guidance

All SDS documents are issued in accordance with applicable chemical safety and transport regulations.

Footnote — SDS Ingestion Guidance
Some Safety Data Sheets (SDS) include standardized ingestion instructions (e.g., “drink milk/water and induce vomiting”). This language reflects general SDS conventions and may not account for local conditions, exposure severity, or individual health factors. Such instructions are intended for initial reference only and do not replace professional medical advice. Inducing vomiting should only be performed if directed by qualified medical personnel.

Scope of Lenovo Battery SDS Documentation

Lenovo-issued SDS documents typically include:

  • Battery chemistry classification and composition

  • Electrical, thermal, and mechanical hazard identification

  • Safe handling, storage, and transport requirements

  • Emergency response and fire-fighting measures

  • Disposal and recycling guidance

These SDS documents apply to battery assemblies supplied with Lenovo products and remain valid throughout the battery’s service life, subject to regulatory updates.

UMC Safety Notice

In any scenario involving:

  • abnormal battery temperature

  • swelling, deformation, or leakage

  • unusual odor, electrical instability, or charging irregularities

SDS guidance takes precedence over software-reported battery health metrics or capacity readings. UMC requires immediate escalation to Lenovo Support or an authorized service provider when SDS-defined safety risks are suspected.

UMC does not authorize battery disassembly, modification, or replacement outside manufacturer-approved service procedures.

Disclaimer

This documentation is provided by United Metrolite Central (UMC) for informational and safety-reference purposes only. UMC does not manufacture, modify, certify, or distribute Lenovo batteries and does not issue Safety Data Sheets (SDS).

All chemical safety, handling, transport, and disposal information originates from Lenovo Group Ltd. and its approved battery vendors. SDS documents, Hardware Maintenance Manuals (HMM), and regulatory compliance statements issued by Lenovo remain the sole authoritative sources.

UMC assumes no responsibility for:

  • improper handling or use of batteries,

  • actions taken without reference to manufacturer documentation,

  • unauthorized repairs, disassembly, or battery replacement,

  • damages resulting from deviation from Lenovo-approved procedures.

Nothing in this documentation should be interpreted as professional repair instruction, chemical safety certification, or manufacturer authorization. Users are responsible for verifying all safety information against the latest official Lenovo documentation.

In the event of suspected battery safety risks—including swelling, overheating, leakage, or electrical instability—UMC requires immediate escalation to Lenovo Support or an authorized service center. Do not continue device operation or attempt corrective action independently.

UMC Security Advisory - Celxpert Battery Issues

Image
Issue date: 30/07/2025  Updated : 31/07/2025  Note:  We updated with example of LNV -5B10W13897 batteries. (Update: UMC officially designated as L17C3PS2.) UMC ID: UMC01-07042   UMC today announced that was issued formal advisory that would recall of current fleet laptops is Lenovo ThinkPad L15 Gen 2a was equipped with Celxpert batteries because that degradation trend was flaw , lasting only 3+ hour battery life as observed. Key findings were included in screenshots. Figure 1: A degradation trend from 45.73Wh to 38.39Wh in Commercial Vantage. Multiple complaints from Reddit users raised concerns over the Celxpert batteries because they degrade into 16% wear level based on observations from linux-hardware.org sites that used to lookup for battery models and concluded that Celxpert (e.g,  LNV-5B10W13897  (L17C3PS2 detected) batteries) was worst long-term retention of advertised watt-hours. UMC recommends AVOIDING  Celxpert-made geninue Lenovo ba...

How I Became a Proactive Battery Monitor (Catching Issues Early)

Author : Felisitas Faya P. Most users notice battery problems only after something feels wrong — shorter runtime, sudden health drops, or unstable charging. By that point, degradation has already accumulated. My goal was different from the start: catch battery issues early , before they become visible, irreversible, or expensive. The Beginning: Observing, Not Assuming (2022) In 2022, I began continuously monitoring battery health on my Lenovo Yoga Slim 7 Carbon 13ITL5. Using Lenovo Vantage Battery Details alongside HWiNFO’s tray monitoring, I tracked capacity, temperature, charging behavior, and long-term trends in real usage. The purpose wasn’t to follow battery myths or chase perfect numbers. It was to understand how batteries actually age over time — slowly, quietly, and often invisibly. Expanding the Scope: Gaming Laptops and Heat (2024) In early 2024, I expanded this monitoring to my first gaming laptop, the IdeaPad Gaming 3 15ACH6. This introduced new variables: higher power draw...
