Hazard Identification
Under normal conditions the battery pack presents no fire, explosion, or chemical leakage hazard. However, the following risks apply in the event of damage or misuse:
- Skin contact: Electrolyte leakage may cause soreness and skin irritation. Remove contaminated clothing and flush with soap and water for at least 15 minutes. Seek medical aid.
- Eye contact: Electrolyte vapors or liquid contact may cause inflammation. Rinse immediately with plenty of water for at least 15 minutes. Remove contact lenses before rinsing. Seek medical aid.
- Inhalation: Vapors or mist from a ruptured battery may cause respiratory irritation. Move to fresh air; administer oxygen or artificial respiration if needed. Seek medical aid.
- 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 casing rupture may release inner components into the environment. Do not allow to enter soil, groundwater, or drains.
Firefighting Measures
The battery is non-flammable under normal conditions. In case of fire or overheating:
- Suitable extinguishing agents: carbon dioxide (CO₂), dry chemical powder, foam.
- Firefighting personnel must wear full-face filter masks or self-contained breathing apparatus (SCBA) and fire/toxic-gas-resistant clothing and gloves.
- Extinguish from the windward side where possible.
- Irritant gases may be emitted if the battery burns or is exposed to open flame.
Accidental Release and Spill Response
In the event of electrolyte release:
- Evacuate personnel from the affected area and keep them upwind of the spill.
- Avoid all skin, eye, and clothing contact with leaked material.
- Ensure adequate ventilation in the area.
- Prevent material from entering soil, drains, or watercourses.
- Pick up spilled material and transfer it to properly labeled recovery containers.
Handling and Storage Guidelines
- Read product instructions carefully before handling the battery.
- Do not crush, puncture, or short-circuit battery terminals with conductive objects.
- Do not directly heat, weld, throw into fire, or disassemble the battery.
- Do not mix different battery types or mix new and used batteries.
- Store batteries on non-conductive trays in a cool, dry, well-ventilated location away from direct sunlight and heat sources.
- Keep away from children.

Frequently Asked Questions
- Q1: What does UN38.3 compliance mean for the ETENWOLF L2 battery pack?
-
ETENWOLF L2 uses a lithium-ion battery pack that has been tested and documented in accordance with UN38.3, the internationally recognized standard covering altitude simulation, thermal cycling, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge tests. UN38.3 compliance is mandatory for the safe transport of lithium batteries by air, sea, and road. Reference No. WTH25D05114738B001 issued by Waltek confirms this documentation is current as of 2025-05-21.
- Q2: Is the lithium-ion battery in the ETENWOLF L2 safe to use during normal operation?
-
Yes. The 1S1P-2600 battery pack (3.7V, 2600mAh, 9.62Wh) used in the ETENWOLF L2 presents no fire, explosion, or hazardous material leakage risk during normal use. The chemical materials are sealed in a robust metal or metal-laminated plastic casing designed to withstand operational temperatures and pressures. Risks only arise in the event of physical damage, improper handling, or exposure to extreme heat or open flame.
- Q3: What should I do if the battery in my ETENWOLF L2 is damaged or leaking?
-
If the battery is visibly damaged or leaking, stop using the device immediately. Avoid skin and eye contact with any leaked electrolyte — if contact occurs, flush thoroughly with water for at least 15 minutes and seek medical attention. Ensure you are in a well-ventilated area, as vapors from a ruptured cell can cause respiratory irritation. Transfer the battery to a properly labeled non-conductive container and dispose of it according to local battery recycling regulations. Do not place a damaged battery in household waste or near flammable materials.
- Q4: What chemical substances are contained in the ETENWOLF L2 battery pack?
-
The ETENWOLF L2 battery pack (model 1S1P-2600) contains ten identified chemical substances. The primary active materials are lithium iron phosphate (LiFePO4, CAS 15365-14-7, 29%) as the cathode and graphite (CAS 7782-42-5, 15.9%) as the anode, with lithium hexafluorophosphate (LiPF6, CAS 21324-40-3, 10.2%) serving as the electrolyte salt. The remaining components are structural and functional materials including PVDF binder, copper and aluminium current collector foils, carboxymethyl cellulose, carbon black, and styrene-butadiene polymer. Full CAS numbers and weight percentages are listed in the Key Details section above.
