The bobbin-type 1/2AA Li-SOCl₂ cell is a compact cylindrical solution delivering 3.6V primary power in a smaller footprint suited to compact sensors, transmitters, and memory-retention modules. Despite its size, the bobbin-type 1/2AA Li-SOCl₂ offers excellent shelf life and stable low-current performance. Manufactured with consistent tolerances, these cells are available with custom leads, weld tabs, or holders for direct integration. They are ideal when space is limited but long-term, maintenance-free energy is required for remote monitoring and embedded systems.
