Protected 18650 Lithium-Ion Battery

Jauch Quartz's protected Lithium-Ion battery has an integrated electronic circuit mounted on top of the bare cell. This circuit protects the battery against common dangers, such as overcharge, over-discharge, short-circuit/overcurrent, and temperature. Protected Lithium-Ion batteries are recommended to use mainly in consumer applications such as flashlights, bike lights, lanterns, table vents, or electronic toys. Protected batteries are less likely to ignite and cause personal or property damage. This Lithium-Ion 18650 battery has an integrated PTC, which protects the battery against overheating and overcurrent.

Furthermore, it has a pressure valve (CID) that regulates the internal pressure of the battery. Unprotected batteries do not have this electronic circuit in the cell packing and because of this, they have a little more capacity and current capability than a protected cell. However, there is always a danger of overheating, short-circuiting, or over-discharging without a safety circuit.
