Nickel Plated A3 Steel Battery Materials 18650 Cylinder Cell Case With Anti Explosive Cap

Cap with Built-in PTC Thermistor for overcurrent protection

PTC resistance: 12 - 15 mΩ

Non-operating current: 3 A (the maximum current under normal operation)

Operating current: 6 A (the minimal current that ensure the circuit breaker was cutoff)

Operating current at 10 A < 8 seconds

(the PTC will react and the battery will be forced to off)

Maximum Voltage: 15 V

Maximum Current: 40 A (the PTC will be breakdown and lost function)

Dimensions

(Dia x Height)

Case: 18mm(OD) x 17.5mm(ID) x 67mm(H)

Top Cap: 17.5mm(D) x 4.05mm(H)

Top Insulator: 12.5mm(D) x 0.19mm(H)

Case and cap are made of Nickel plated A3 steel

Sealing spacers are made of nylon

The insulating gasket is made of PET

Safety valve's open pressure: 2.5MPa (the cap valve will open to release interior high pressure -- if over 2.5MPa -- to ensure the can does not explode)

18650 case's grooving and sealing machine is available upon request

Safety protection: Positive Temperature Coefficient (PTC) Thermistor is built into the cap

PTC Thermistor will break the current when heated to 120ºC
