The CR17450 Li-MnO₂ battery combines a larger energy reserve with the discharge capability required by active wireless electronics. With an approximately 17 mm diameter and 45 mm height, it is commonly selected when a device needs longer field operation than smaller cylindrical primary cells can comfortably provide, but still experiences recurring periods of higher current demand.
This operating profile is especially common in industrial and commercial IoT equipment. A device may remain in low-power monitoring mode for most of its service life, then periodically activate a radio module, positioning circuit, alarm, sensor, or communication interface. CR17450 is well suited to these mixed-load conditions because it can support both long-duration energy consumption and intermittent pulse events.
Designed for Long-Life Wireless Equipment
Many battery-powered industrial devices are installed with the expectation that they will operate for years with minimal maintenance.
CR17450 provides the additional stored energy needed for these extended deployments while retaining the ability to respond to periodic active loads. This makes it particularly useful for devices where increasing battery replacement intervals is important, but low-power standby performance alone is not sufficient.
A Practical Choice for Communication Pulses
Wireless technologies such as NB-IoT, LoRa, GPS, and other telemetry systems can create brief increases in current whenever the device transmits or acquires data.
For suitable electrical profiles, CR17450 can deliver these short-duration loads directly, allowing designers to build compact primary battery systems without necessarily relying on a separate pulse-support component.
The final battery configuration should still be evaluated against the actual pulse current, pulse duration, transmission frequency, cutoff voltage, operating temperature, and expected service life of the equipment.
Typical Applications
Utility Meters
Suitable for smart water meters, smart gas meters, heat meters, and other utility endpoints that combine long standby periods with scheduled NB-IoT, LoRa, or similar wireless communication.
Long-Life Smoke & CO Detectors
Applicable to selected standalone smoke alarms and carbon monoxide detectors designed for extended maintenance intervals and long-term primary battery operation.
Intelligent Transportation
Used in applications such as ETC on-board units, wireless parking sensors, and transportation monitoring devices requiring compact, maintenance-efficient power.
Asset Tracking & Logistics
Well suited to container GPS trackers, cold-chain monitoring equipment, logistics sensors, and telemetry devices that periodically activate positioning, sensing, and wireless data transmission.

Selecting CR17450 for an OEM Application
Battery selection should be based on the complete operating profile rather than capacity alone.
For an OEM project, Lithogenix can evaluate factors such as standby current, active current, pulse demand, communication interval, target service life, operating temperature, battery compartment dimensions, and connection requirements to determine whether CR17450 is appropriate for the intended device.
