Key Features – 22430 Lithium Battery 3 7V

🚀 High Energy Density for Maximum Runtime

With an energy density reaching 172.09Wh/kg, this 22430 lithium-ion cell delivers more usable energy in less space and weight. Compared with conventional cylindrical cells, it allows device manufacturers to extend runtime without increasing battery size, making it especially suitable for portable, handheld, and lightweight equipment.

🔥 Stable 3C Continuous Discharge Performance

Designed for demanding power requirements, the cell supports continuous 3C discharge, delivering up to 6A of stable output current. This ensures reliable operation in devices with sustained power draw, minimizing voltage sag and thermal stress during extended use.

🧩 Excellent Cell Consistency for Battery Pack Integration

Each cell undergoes strict matching and quality control to ensure high consistency in capacity, internal resistance, and voltage behavior. This makes the 22430 cell particularly well-suited for multi-series and multi-parallel battery packs, improving overall pack safety, lifespan, and balance efficiency.

📏 Compact 43mm Height for Space-Sensitive Designs

With a height of just 43mm, this 22430 lithium-ion cell is significantly more compact than many traditional cylindrical cells. It is an excellent choice for applications with strict dimensional constraints, enabling more flexible mechanical design and higher packing efficiency.

♻️ Long Cycle Life with Reliable Capacity Retention

The cell is engineered for 500+ deep charge-discharge cycles, and even after 500 cycles, it retains more than 1600mAh of usable capacity. This long cycle life reduces replacement frequency, lowers maintenance costs, and improves the overall sustainability of battery-powered systems.

❓ Frequently Asked Questions (FAQ)

Q1: What is a 3C battery?

A 3C battery is a battery that can safely deliver a continuous discharge current equal to three times its rated capacity. For example, a 2000mAh 3C battery can continuously output up to 6A without damaging the cell.

Q2: How many hours can 2000mAh last?

2000mAh battery can theoretically last 2 hours at a 1A draw, 4 hours at 0.5A, or 1 hour at 2A. Actual runtime varies depending on discharge rate, efficiency, and operating conditions.

Q3: Does a new battery need to be fully charged?

No, a new battery does not need to be fully charged before first use, as modern lithium-ion batteries come partially charged and ready to use. However, charging it to 100% once can help calibrate the battery indicator.

Q4: Can you overcharge a new battery?

Yes, a battery can be overcharged if it’s connected to a faulty charger or lacks proper protection circuitry. However, modern lithium-ion batteries with a BMS and certified charger automatically stop charging when full, preventing overcharge.

Q5: What not to do with a lithium battery?

Do not overcharge, over-discharge, short-circuit, crush, or expose a lithium battery to high heat or fire. Also avoid using damaged chargers or storing the battery fully drained for long periods.
