At 18650 Battery Partners, your safety is our top priority. Lithium-ion batteries offer powerful and efficient energy storage, but improper handling or misuse can result in fire, explosion, serious injury, or death. Please review and follow these critical safety guidelines before purchasing, handling, or using any lithium-ion battery.
⚠️ Understanding the Risk: Short Circuits
A short circuit occurs when the positive (+) and negative (–) terminals come into contact, allowing uncontrolled electrical flow. This can cause:
🔥 Rapid heat buildup
💥 Fire or explosion
⚠️ Severe injury or property damage
Note: The entire outer casing of a cylindrical lithium-ion cell acts as the negative terminal. Insulation is essential to prevent accidental contact with conductive materials.
🔥 What is Thermal Runaway?
Thermal runaway is a hazardous reaction where a battery overheats uncontrollably, often resulting in fire or explosion.
Causes Include:
Overcharging beyond the cell's voltage limits
Internal or external short circuits
Physical damage (dents, punctures, or cracks)
Exposure to high temperatures
Warning Signs:
Swelling or deformation
Smoke, odor, or leakage
Overheating beyond normal charging temperature
How to Prevent It:
Use a smart charger designed for lithium-ion cells
Avoid overcharging or over-discharging
Store in a cool, dry location, away from heat sources
Inspect batteries before each use
In Case of Thermal Runaway:
Stop using the battery immediately
Move it to a fireproof surface (e.g., concrete or sand)
Keep it away from flammable materials
If it ignites, use a Class D fire extinguisher or dry sand
❗ Never use water
✅ Key Safety Guidelines
🧰 General Handling
🔍 Inspect before each use – Do not use if the battery is damaged, leaking, or missing insulation
🛑 Do not carry loose batteries – Always store in protective cases
✅ Ensure the PVC wrap and top insulator are intact
⚡ Charging Safety
⚠️ Use only adedicated lithium-ion smart charger
⚠️ Match charger voltage to battery specifications
🔥 Charge only on non-flammable surfaces
👁️ Monitor charging – Never leave unattended
📦 Storage & Transport
Store in protective packaging or battery cases
Keep in a cool, dry place, away from direct sunlight or liquids
🚫 Keep out of reach of children and pets
🚫 Prohibited Activities
❌ Do not use damaged batteries
❌ Do not short-circuit the terminals
❌ Do not expose to liquids or humid environments
❌ Do not overcharge or over-discharge
❌ Do not solder directly to the battery (spot welding only)
❌ Do not crush, puncture, disassemble, or modify the battery
❌ Do not mix brands, capacities, or charge levels in the same device
❌ Do not throw in trash – Recycle properly
🚨 Emergency Situations
⚠️ Skin or Eye Contact with Electrolyte:
Rinse withcopious amounts of water
Seek immediate medical attention
🔥 If the Battery Catches Fire:
Use a Class D fire extinguisher or dry sand
❗ Never use water or a standard fire extinguisher

📌 Your Responsibility
Using lithium-ion batteries safely requires vigilance, knowledge, and proper equipment. By following these safety guidelines, you help protect yourself, others, and your property.
⚠️ Lithium-Ion Battery Safety Advisory
Lithium-ion batteries are powerful energy sources, but improper handling, usage, or storage can result in fire, explosion, or thermal runaway, potentially causing serious injury, property damage, or fatality. All customers must review and adhere to the following critical safety guidelines before purchasing or operating any lithium-ion cells. ➡️ Click Here for our Full Saftey Guidelines
At 18650 Battery Partners, your safety is our top priority. Lithium-ion batteries must be handled and used with care. Misuse may result in fire, explosion, or thermal runaway, posing a risk of serious injury or property damage. Please read and follow all safety protocols prior to purchase or use.
Never carry loose batteries in your pocket, bag, or purse. Contact with keys or coins can cause a short circuit, potentially leading to burns, fire, or explosion. Always use a protective, non-conductive case for storage and transport.
✅ Intended Use Only
These cells are intended for integration into battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). They must not be used in standalone form or installed in consumer devices such as vape pens, e-cigarettes, or flashlights.
🔥 Understanding Thermal Runaway
Thermal runaway is a hazardous chain reaction triggered by excessive internal heat, which may lead to fire or explosion. It can be caused by overcharging, physical damage, short circuits, or high external temperatures. To prevent it, use a smart charger, avoid mechanical damage, and store batteries in a cool, dry environment.
📦 Storage & Handling
Always keep batteries in individual protective cases and away from metal or conductive materials. Avoid storing them in humid, hot, or direct sunlight-exposed areas to maintain safety and integrity.
🛠 Visual Inspection
Do not use any battery that appears dented, bulging, leaking, corroded, or with damaged insulation or wrapping. Any visual damage indicates a compromised cell that may pose a serious hazard.
⚡ Charging Precautions
Use only chargers specifically designed for lithium-ion batteries. Avoid overcharging, over-discharging, or leaving the battery unattended while charging. Disconnect promptly once the battery reaches full charge.
🚫 Prohibited Activities
Do not expose batteries to open flame, excessive heat, or liquids. Do not puncture, crush, short-circuit, or modify the cells in any way. Never operate or charge batteries outside the manufacturer's recommended voltage range, and never dispose of them in household trash—recycle at certified facilities.
🧯 Emergency Procedures
If a battery overheats, emits smoke, leaks, or swells, stop using it immediately. Move it to a fireproof surface like sand or concrete, and isolate it from other items. If it ignites, use a Class D fire extinguisher or sand to put out the fire—do not use water.
