COROS CLH-20 ER33600 3.6V 14.5Ah D Size Lithium Primary Battery (120 Batteries)

COROS CLH-20 ER33600 3.6V 14.5Ah D Size Lithium Primary Battery

(Carton of 120 Batteries)

The COROS CLH-20 is a high-performance 3.6V lithium primary battery built on Li-SOCl₂ chemistry and designed in a D-size spiral configuration. With a nominal capacity of 14.5Ah, this ER33600-standard cell is engineered for long operational life and stable voltage output, making it ideal for mission-critical applications that demand reliability over extended periods.

Capable of delivering up to 2000mA continuous current and 3000mA pulse current, the CLH-20 performs consistently across extreme temperatures ranging from -55°C to +85°C. Certified under UL filing MH66316 and available with multiple terminal and connector options, this battery is well-suited for industrial, utility, and remote monitoring systems where maintenance access is limited.
