Hazard Identification Summary
The Lithium-ion Battery Pack 2S1P-2000 is not dangerous under normal use. The following hazard information applies in the event of battery rupture or improper handling.
- Skin Contact: Electrolyte leakage may cause skin soreness and irritation. Remove contaminated clothing and flush with soap and plenty of water for at least 15 minutes. Seek medical aid.
- Eye Contact: Electrolyte vapour may cause eye irritation and inflammation. Rinse immediately with plenty of water; remove contact lenses before rinsing. Seek medical aid.
- Inhalation: Inhalation from a sealed battery is not an expected exposure route. Vapours or mists from a ruptured battery may cause respiratory irritation. Move to fresh air; administer oxygen or artificial respiration if needed.
- Ingestion: Swallowing is not anticipated due to battery size. If electrolyte is ingested, dilute with plenty of water and seek medical aid immediately. Do not give anything by mouth to an unconscious person.
- Environmental: Electrolyte leakage or container rupture may release inner components into the environment. Do not allow product to enter soil, groundwater, or drains.
Fire-Fighting Information
| Property | Detail |
|---|---|
| Flammability | Non-flammable under normal conditions |
| Risk on Overheating | May leak combustible electrolyte fumes |
| Combustion Products | Irritant gases if burned or exposed to fire |
| Recommended Extinguishants | Carbon dioxide, dry chemical, foam |
| Protective Equipment | Full-face filter mask or isolated breathing apparatus; fire- and toxic-gas-resistant clothing and gloves |
Handling and Storage Guidelines
- Read the product specification carefully before handling.
- Do not crush, pierce, or short-circuit the battery terminals with conductive materials.
- Do not directly heat, solder, or dispose of in fire — risk of explosion.
- Do not mix different battery types or mix new and used batteries.
- Store in a non-conductive tray in a cool, well-ventilated area away from heat sources.
- Evacuate personnel and ensure adequate ventilation in the event of electrolyte spill.
- Contain spills and transfer material to properly labelled containers for recycling.

Frequently Asked Questions
- What does reference number WTH26D03058717B001 identify?
- Reference number WTH26D03058717B001 is the unique document identifier assigned by Waltek Testing Group Co., Ltd. to the Material Safety Data Sheet for the Lithium-ion Battery Pack model 2S1P-2000 (7.4V, 2000mAh, 14.8Wh) manufactured by Guangdong Bestek Technology Co., Ltd. It allows the document to be traced back to its issuing laboratory and specific product batch.
- Is the Lithium-ion Battery Pack 2S1P-2000 dangerous during normal use?
- No. Under normal operating conditions, the Lithium-ion Battery Pack 2S1P-2000 presents no risk of ignition, explosion, or hazardous material leakage. Chemical materials are stored in a sealed enclosure designed to withstand normal temperature and pressure ranges. Hazards described in the MSDS apply only in fault scenarios such as mechanical damage, short circuit, fire exposure, or improper dismantling.
- What first-aid steps should be taken if the battery ruptures and electrolyte contacts skin?
- Remove all contaminated clothing immediately and flush the affected area with soap and plenty of water for at least 15 minutes. Seek medical aid promptly. If electrolyte contacts eyes, rinse with plenty of water immediately, remove contact lenses before rinsing if worn, and do not allow the person to rub their eyes. In all cases of significant exposure, professional medical assistance should be obtained.
- What fire extinguishants are safe to use on a burning lithium-ion battery pack?
- Carbon dioxide (CO2), dry chemical powder, and foam extinguishants are recommended. Fire-fighting personnel must use a full-face filter mask or an isolated breathing apparatus and wear clothing and gloves resistant to fire and toxic gas. Where the battery is burning alongside other combustible materials, apply the fire-fighting method appropriate to those combustibles and extinguish from upwind where possible.
