For FDK LG EIectronics EAC63379801 PACK
Package includes:
1PC EAC63379801
Battery Ultra-high energy density: Approximately 500?C700 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?C20 years at room temperature.
Wide operating temperature range: Stable performance from -55?? to +85??.
Structure: Lithium metal negative electrode; thionyl chloride (SOCl?) 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:
série connection: Boosts voltage (e.g., 2 cells in série 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
