Product Description
26700 3500mAh 3V Sodium-Ion Battery
Features
- Enhanced Safety: Sodium-ion chemistry is inherently more stable than some lithium-ion chemistries, exhibiting higher thermal runaway temperatures and being less prone to catching fire or exploding under abusive conditions like overcharging, short-circuiting, or physical damage .
-
Excellent Low-Temperature Performance: Maintains a higher discharge efficiency in cold environments compared to many Li-ion batteries, making it suitable for outdoor applications in winter .
-
High Power & Fast Charging: Capable of supporting high discharge rates (e.g., for power tools) and can be charged relatively quickly .
-
Cost-Effective & Eco-Friendly: Sodium resources are abundant and widely distributed, leading to potentially lower material costs and a more stable supply chain than lithium. The technology is also considered more environmentally benign .
-
Long Cycle Life: Designed for long-term use, with a cycle life that can exceed 2000 cycles under standard discharge conditions .

Warnings & Safety Instructions
Charging
- Use Designated Chargers: Charge only with a charger specifically designed for sodium-ion batteries with the correct voltage and current limits. Using an incorrect charger is dangerous.
-
Temperature Control: Do not charge outside the specified temperature range (0°C to +55°C). Charging in extreme temperatures can cause permanent damage or hazard .
-
Avoid Overcharging: Do not leave the battery connected to the charger indefinitely after it is fully charged.
Discharging
- Voltage Limit: Do not discharge the battery below the recommended cut-off voltage. Deep discharge can irreversibly damage the battery.
-
Current Limit: Do not exceed the maximum continuous discharge current specified for the pack.
-
Temperature Monitoring: If the battery pack becomes excessively hot during use, stop operation and allow it to cool down.
Storage & Disposal
- Ideal Storage Charge: For long-term storage (longer than one month), store the battery at a state of charge between 30% and 50%.
-
Storage Environment: Store in a cool, dry place away from direct sunlight, heat sources, and moisture.
-
Disposal: Do not dispose of in regular trash. As a rechargeable battery, it must be recycled or disposed of according to local regulations at designated recycling centers.
