3.7V 1900mAh INR18500 Lithium Ion Battery

VCELL POWER high quality 3.7V 1900mAh INR18500 lithium ion battery uses lithium nickel manganese cobalt oxide material, resulting in high energy density. Its cylindrical design is compact and offers long-lasting battery life. An explosion-proof valve on the top of the battery quickly releases internal pressure in abnormal situations, effectively preventing battery rupture or fire. High-quality electrode materials and precision manufacturing processes ensure battery life, providing over 700 charge-discharge cycles under standard conditions, offering excellent value. It is widely used in various professional lighting, power tools, medical equipment, security communications, and high-end consumer electronics products.

Material System

This battery adopts lithium nickel cobalt manganese oxide (LiNiCoMnO2, INR) as cathode material. Compared with traditional lithium cobalt oxide system, INR material has the following advantages:

1.High energy density: It can store more electricity in the same volume and satisfy the lightweight requirements of devices.

2.Good thermal stability: The material structure remains stable under high temperature, lowering the risk of thermal runaway.

3.Balanced rate performance: It supports 3.0C continuous discharge and 5.0C peak discharge to meet intermittent high current demands.

Core Advantages

The 3.7V 1900mAh INR18500 Lithium Ion Battery integrates excellent safety, long cycle life and reliable stability. Its main strengths are as follows:

1.Explosion-proof structure: The top explosion-proof valve quickly releases pressure when internal pressure rises abnormally, effectively avoiding potential safety hazards. Combined with diaphragm explosion-proof layer, it provides dual structural protection.

2.Over 700 cycle life: Under standard charge and discharge conditions (0.2C charge / 0.2C discharge), the battery can complete more than 700 cycles and maintain high capacity afterwards, reducing device replacement frequency.

3.Wide operating temperature range: Discharging works from -20℃ to +60℃ and charging ranges from 0℃ to +45℃, adapting to various indoor and outdoor working environments.

4.Eco-friendly & compliant: It complies with RoHS standards and contains no harmful substances.

FAQ

Q: What does INR stand for in INR18500?

A: INR refers to lithium nickel cobalt manganese oxide (LiNiMnCoO2) material system, a type of ternary lithium ion battery. It is characterized by high energy density and balanced rate performance.

Q: What is the difference between this battery and 18650 battery?

A: Both share the same diameter of 18mm, while INR18500 is shorter in height (50mm vs 65mm) with smaller overall size, making it more suitable for devices with limited installation space. Its 1900mAh capacity is lower than regular 18650 batteries which generally range from 2000mAh to 3000mAh.

Q: What about the capacity retention after 700 cycles?

A: The actual capacity retention varies according to working environment, charge-discharge rate and storage conditions.

Q: How does the explosion-proof valve work?

A: When internal pressure rises sharply due to overcharging, short circuit and other abnormal situations, the explosion-proof valve will rupture to release pressure, so as to reduce the risk of shell damage.

Q: Can you customize batteries with plugs or wires?

A: Yes. Vcell Power supports custom assembly of protection boards, wires and connectors on cells to make customized battery packs.

Q: How to store this battery properly?

A: It is recommended to store the 3.7V 1900mAh INR18500 Lithium Ion Battery in a dry environment at 20±5℃. For long-term storage, keep the battery voltage between 3.7V and 3.9V (about 40%-60% remaining power), and recharge it every 3 to 6 months.
