For FDK LG EIectronics EAC63379801 PACK
Package includes:
1PC EAC63379801
Battery Ultra-high energy density: Approximately 500-700 Wh/kg, ranking among the highest of commercial primary batteries. Extremely low self-discharge: Annual self-discharge rate below 1%, with a shelf life of 10-20 years at room temperature.
Wide operating temperature range: Stable performance from -55°C to +85°C
Structure: Lithium metal negative electrode; thionyl chloride (SOCl2) serves as both the positive electrode active material and electrolyte; fully hermetically sealed by welding.
Types
Capacity type (carbon-wound construction): Ideal for micro-current and long-lifespan applications (water meters / electricity meters / gas meters). Power type (wound cell construction): Capable of sustaining large pulse currents (e.g., communication modules, security systems).
II. Lithium Thionyl Chloride Battery Pack
It is assembled by connecting multiple lithium thionyl chloride cells as required:
Series connection: Boosts voltage (e.g., 2 cells in series output 7.2V).
Parallel connection: Increases total capacity and extends operating duration.
Common models: Modules assembled from ER14505, ER18505, ER34615 and other cell types.
Typical applications: Smart meters, IoT terminals, PLCs, security systems, medical equipment, field monitoring devices, etc.
III. Core Advantages & Disadvantages
Advantages
Ultra-long standby and service life (matches the service life of host equipment, maintenance-free).
Extremely stable voltage (maintains 3.6V across most of its discharge capacity).
Excellent resistance to extreme temperatures and reliable waterproof sealing performance.
High energy density, compact size and lightweight design.
Disadvantages & Precautions
Strictly non-rechargeable; short circuit, overcharging or high temperature exposure may cause explosion and toxic electrolyte leakage.
Passivation effect occurs: The initial discharge voltage drops after long-term storage, requiring low-current "activation".
Higher cost than conventional batteries.
Limited continuous discharge current for single cells (typically several tens of milliamps for capacity-type cells).
IV. Common Application Scenarios
Smart water / electricity / gas meters, heat meters
IoT sensors, wireless meter reading devices, 4G/NB-IoT modules
Security alarms, smoke detectors
Industrial instruments, PLC backup power supplies
Implantable / portable medical devices, field monitoring equipment
