The UPC1550 Battery Capacitor is the largest format in the Lithogenix UPC series, intended for applications where both the lifetime energy demand and short-duration power demand are substantially higher than in conventional low-power IoT devices.
With an approximate size of 15 mm in diameter and 50 mm in height, UPC1550 is typically integrated with larger Li-SOCl₂ cells such as ER26500 or ER34615. The primary battery supplies the long-term energy reserve, while the capacitor supports high-current events associated with communication, system wake-up, emergency transmission, or other short active loads.
Heavy-Duty Pulse Support for Long-Life Systems
Large industrial and remote-monitoring devices may remain deployed for many years, but they are not necessarily low-power systems.
Long-range communication, satellite uplinks, GSM-based telemetry, positioning modules, and industrial sensors can create short periods of significantly higher current demand.
UPC1550 provides an additional pulse-energy reserve so that these events do not rely entirely on the primary Li-SOCl₂ cell.
This makes the ER + UPC1550 architecture particularly relevant when the system combines:
- long unattended operation
- large lifetime energy demand
- recurring high-current transmission
- difficult maintenance access
- harsh outdoor or industrial environments
Matched to High-Capacity Li-SOCl₂ Cells
UPC1550 is most commonly considered alongside larger ER cells where the system must operate for extended periods between service visits.
An ER26500 or ER34615 can provide the long-term energy budget, while UPC1550 supports short-duration power requirements during communication or other active events.
This separation between energy storage and pulse delivery can be especially useful in equipment where transmission power is high relative to the device’s average consumption.
Typical Hybrid Applications
Industrial Flow Meters & Pipeline Monitoring
Suitable for large-diameter flow meters, underground pipeline monitoring equipment, remote valve electronics, and distributed utility infrastructure requiring long service intervals and periodic long-range communication.
GSM-Based Metering & Asset Tracking
Can support smart metering and tracking devices using GSM or similar cellular communication, where network registration and data transmission create significant short-duration current peaks.
Marine Buoys & Remote Ocean Monitoring
Applicable to selected oceanographic buoys, offshore monitoring systems, tsunami warning equipment, and marine telemetry devices that combine long unattended deployment with demanding satellite or long-range wireless communication.
Automotive Emergency Communication
UPC1550 can be considered within dedicated backup power architectures for automotive eCall and emergency communication systems that must support communication and positioning functions after the vehicle’s primary electrical supply is interrupted.
Remote Industrial Telemetry
Well suited to field equipment using high-power radio, cellular, or satellite communication where a large ER battery provides lifetime energy and the capacitor supports communication peaks.
High-Temperature Industrial Applications
Specialized oil and gas equipment can place exceptionally demanding temperature and reliability requirements on the battery system.
For downhole measurement, MWD/LWD, or other high-temperature applications, only specifically designed and qualified high-temperature battery and capacitor versions should be used.
A standard UPC1550 should not be assumed suitable for downhole service without confirming the required temperature rating, sealing system, electrical performance, and qualification conditions.
Standalone Energy Buffering
UPC1550 may also be used as a short-duration energy buffer in selected industrial electronics where rapid energy delivery is more important than long continuous runtime.
Examples can include temporary control-system support, data retention, communication completion, or power-loss handling during brief interruptions.
In automated equipment or mobile industrial systems, the capacitor may support short electronic loads during charging transitions or power handover events, but suitability depends on the actual energy requirement and should be validated at system level.
Designed for Demanding Deployment Conditions
The larger UPC1550 format is intended for systems where reliability over extended deployment periods is critical.
Its laser-sealed construction supports enclosure integrity for industrial and outdoor applications, while the larger capacitor format provides greater flexibility for demanding pulse-load profiles than smaller UPC models.
The final performance of the hybrid system will still depend on operating temperature, pulse frequency, recovery time, battery condition, and the electrical architecture of the device.
