The VL2330 coin cell is a rechargeable lithium vanadium pentoxide (Li-V₂O₅) battery, offering stable voltage and excellent endurance across hundreds of charge/discharge cycles. Unlike traditional CR (primary) or BR (long-life primary) cells, the VL2330 is designed for repeated recharging, making it ideal for applications that require continuous operation without frequent replacement.

With a nominal capacity of ~50mAh, it delivers reliable power in a compact 23mm × 3.0mm form factor. The 2-pin leg connector version is particularly suitable for direct PCB soldering, ensuring secure mounting in embedded systems.

Its wide operating temperature range (-20°C to +60°C) and low self-discharge rate make it highly reliable for real-time clocks (RTC), memory backup, automotive electronics, IoT devices, and security equipment.

This coin cell provides an eco-friendly alternative to disposable CR cells by supporting rechargeable use with a recommended charge voltage of 3.2V and long cycle durability.
