Product Description
The 4680 battery is Tesla's new generation of cylindrical batteries with a diameter of 46mm and a height of 80mm. For batteries, when the energy density increases, the power density decreases, and the 46mm diameter is the optimal choice for cylindrical batteries to combine high energy density and high power density.
Product Parameters
Core innovation, performance breakthrough, large cell + full lugs + dry cell technology
4680 batteries significantly increase the battery power (6 times more than 2170 batteries), reduce the battery cost (14% more than 2170 batteries), optimize the heat dissipation performance, production efficiency, charging speed, energy density, cycle performance has further room for improvement.

Performance Specification
1. Standard Charge Unless otherwise specified, "Standard Charge" shall consist of charging at constant current of 0.5C. The cell shall then be charged at constant voltage of 4.20V while tapering the charge current. Charging shall be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be performed at 23ºC ± 2ºC.
2. Standard Discharge "Standard Discharge" shall consist of discharging at a constant current of 0.2C to 2.50V. Discharging is to be performed at 23 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature).
3. High Drain rate Charge/discharge condition Cells shall be charged at constant current of 1,500mA to 4.20V with end current of 100mA. Cells shall be discharged at constant current of 4,000mA to 2.50V. Cells are to rest 10 minutes after charge and 20 minutes after discharge.
Caution Warning
* When using the application equipped with the battery, refer to the user's manual before usage.
* Please read the specific charger manual before charging.
* Charge time should not be longer than specified in the manual.
* When the cell is not charged after long exposure to the charger, discontinue charging.
* Battery must be charged at operating temperature range 0 ~ 45ºC.
* Battery must be discharged at operating temperature range -20 ~ 60ºC.
* Please check the positive(+) and negative(-) direction before packing.
* When a lead plate or wire is connected to the cell for packing, check out insulation not to short-circuit.
* Battery must be stored separately.
* Battery must be stored in a dry area with low temperature for long-term storage.
* Do not place the battery in direct sunlight or heat.
* Do not use the battery in high static energy environment where the protection device can be damaged.
* When rust or smell is detected on first use, please return the product to the seller immediately.
* The battery must be away from children or pets
* When cell life span shortens after long usage, please exchange to new cells.
* Do not use different charger. Do not use jacks (in cars) for charging.
* Do not charge with constant current more than maximum charge current.
* Do not disassemble or reconstruct the battery.
* Do not throw or cause impact.
* Do not pierce a hole in the battery with sharp things. (such as nail, knife, pencil, drill)
* Do not use with other batteries or cells.
* Do not solder on battery directly.
* Do not press the battery with overload in manufacturing process, especially ultrasonic welding.
* Do not use old and new cells together for packing.
* Do not expose the battery to high heat. (such as fire)
* Do not put the battery into a microwave or high pressure container.
* Do not use the battery reversed.
* Do not connect positive(+) and negative(-) with conductive materials (such as metal, wire)
* Do not allow the battery to be immerged in or wetted with water or sea-water
