Safe And Reliable, Smart Choice - Unveiling The Safe Core of Cylindrical Lithium 3.7V Battery

While performance is important, safety always comes first. We are well aware that every battery is related to the reputation of the final product and the safety of the user. Therefore, in the design of cylindrical lithium 3.7V batteries, we place safety concepts at the core.

1、 Multiple security protection mechanisms

We have built-in multi-level safety protection for the battery:

PTC (Positive Temperature Coefficient) component: When the current is too high or the temperature is too high, the PTC resistance will increase sharply, effectively cutting off the current and preventing the danger of overheating.

CID (Current Interruption Device): When the internal pressure of the battery rises abnormally, CID will automatically activate, permanently disconnecting the current path and fundamentally eliminating the risk of explosion.

Safety valve: As the last physical line of defense, the safety valve can release pressure in extreme situations, ensuring the integrity of the battery cell structure.

2、 Robust physical structure

The cylindrical structure itself has inherent mechanical strength advantages, which can effectively resist external impacts and compressions. Our battery casing is made of high-quality steel and manufactured with precision technology, providing strong physical protection and reducing the risk of short circuits and leakage.

3、 Strict quality control

From raw material screening to finished product delivery, each battery undergoes dozens of strict quality inspection processes. We use:

High/low temperature testing to verify its environmental adaptability.

Verify the effectiveness of the protection circuit through overcharge/overdischarge testing.

Acupuncture and compression tests ensure its mechanical safety limits.

Cycle life testing ensures the reliability of its long-term use.

4、 Intelligent BMS solution (for battery packs)

For battery packs composed of multiple power-saving cells, we provide a matching intelligent battery management system (BMS). BMS can monitor the voltage, current, and temperature of each battery in real time, achieve precise charge and discharge management, power balance, and fault warning, and elevate system safety to a new level.

Conclusion: Our cylindrical lithium 3.7V battery is not only an energy source, but also a carefully crafted safety fortress. We promise that every energy we provide to you contains an infinite dedication to safety.
