Whether deployed inside automated municipal utility meters in Riyadh or mission-critical security hardware across the Eastern Province, this cell maintains reliable operating voltage without severe passivation delays under extreme ambient conditions.

Key Performance Advantages

Engineered to handle high instantaneous current spikes, the Ramway CR17450 incorporates several verified electrical and structural design benefits:

1. Spiral Electrode Architecture: Unlike low-current bobbin cells, the spiral-wound internal structure facilitates continuous discharge currents up to 1500mA and dynamic RF transmission pulses reaching 3000mA.
2. Stable 3.0V Discharge Plateau: Keeps device circuits running cleanly near nominal voltage throughout the service cycle, preventing unexpected low-voltage dropouts in telemetry hardware.
3. Minimal Storage Degradation: Demonstrates an ultra-low self-discharge rate of less than 2% over a two-year storage period at 25°C, ensuring high readiness for field replacement stock.
4. Robust Semi-Hermetic Enclosure: Encased in a rugged stainless steel canister equipped with semi-hermetic sealing to stop electrolyte leakage and defend against internal corrosion.
5. Wide Thermal Resilience: Engineered to discharge smoothly within ambient operating conditions spanning from -40°C to +70°C, addressing severe regional temperature swings.
6. Certified Production Quality: Manufactured under an ISO9001 quality management framework and recognized under UL, CE, and SGS electrical and environmental testing standards.

Discharge & Pulse Characteristics

Laboratory load curves illustrate the performance profile of the Ramway lithium battery cr17450 3v under varying current draws and operational temperatures:

1. Continuous Resistive Drains: At 23°C, loads between 2800Ω (1mA baseline) and 280Ω (10mA) maintain a flat 3.0V output for thousands of hours, while heavy 5.6Ω continuous loads (500mA) deliver reliable voltage down to the 2.0V cutoff.
2. Thermal Capacity Retention: Under a constant 60Ω load, operating at elevated temperatures (up to 60°C) sustains a dependable discharge plateau (~2.8V), while sub-zero environments (-20°C) still retain useful working voltage above 2.0V.
3. Cyclic Pulse Resilience: Testing with a 0.9A pulse pattern (3 seconds active transmission, 27 seconds standby) confirms that the CR17450 Li-MnO2 battery handles over 2,000 to 2,800 duty cycles without sudden terminal collapse.

Applications

The high-rate output and low standby drain make this cr17450 3v battery an effective power source across multiple industrial and commercial sectors:

1. Automated Meter Reading (AMR) & Utility Telemetry: Delivers pulsed energy to GPRS, LoRaWAN, and NB-IoT communication transceivers in smart water, gas, and heat meters.
2. Commercial Security & Alarm Hardware: Powers wireless passive infrared (PIR) intrusion detectors, glass-break sensors, and high-frequency wireless panic transmitters.
3. Automotive & Electronic Toll Collection: Provides durable power for on-board units (OBU), active RFID toll tags, and commercial fleet tracking beacons operating under direct windshield heat.
4. Industrial Memory Backup & SCADA: Safeguards volatile SRAM chips, field data loggers, programmable logic controllers (PLCs), and remote pipeline monitoring devices.
5. Remote Field & Emergency Electronics: Functions as an energy reserve in remote environmental sensing stations, signal beacons, and professional measuring tools.

How to Use / Install

Follow these sequential handling steps to ensure safe electrical integration and long service life:

1. De-energize Equipment: Switch off the target device and isolate auxiliary circuits before battery replacement or installation.
2. Inspect Terminals & Polarity: Verify that the equipment contact springs are clean and properly identify the positive (+) raised button top and flat negative (-) terminal.
3. Seat the Cell: Slide the Ramway cr17450 battery gently into the battery carrier without using excessive force or sharp metallic tools.
4. Seal the Enclosure: Fasten the compartment gasket or lid securely to maintain IP-rated environmental protection against industrial dust and ambient humidity.
5. Perform Diagnostics: Power on the unit and check system telemetry or voltage diagnostics to confirm initial operating potential above 3.0V.

Precautions & Safety

Because the Ramway cr17450 battery contains high-energy lithium metal and active cathode materials, strictly adhere to these verified safety warnings:

1. Non-Rechargeable Primary Cell: Never attempt to recharge this battery. Connecting to a charging circuit risks electrolyte venting, structural rupture, or fire.
2. Strict Thermal Thresholds: Never expose the cell to open flame or temperatures exceeding 100°C. Prolonged operation above 70°C degrades internal chemistry.
3. No Direct Canister Soldering: Do not apply soldering irons directly to the stainless steel body. Excessive thermal conduction damages the internal safety vent and semi-hermetic seals; use factory-welded solder tabs or battery holders instead.
4. Mechanical Integrity: Do not puncture, crush, disassemble, deform, or drop the battery. Damaged outer casing destroys the moisture barrier.
5. Short-Circuit Prevention: Never transport or store loose cells alongside conductive materials like wire cuttings, tools, or metallic components.
6. Responsible Disposal: Depleted primary lithium cells must be disposed of in accordance with regional Saudi hazardous waste guidelines and environmental recycling standards.

FAQs

Common technical and operational questions regarding the Ramway CR17450 battery 3V 2200mAh cell:

1. What is the primary function of the Ramway 3V CR17450 2200mAh Lithium Battery?
   It provides dependable 3.0V primary DC power for electronic systems requiring low baseline background current paired with high periodic RF pulses, such as automated utility meters, wireless security sensors, and automotive transponders.
2. What is the difference between this spiral cell and a bobbin-type lithium cell?
   Spiral cells, such as this CR17450, utilize rolled electrode sheets to create a larger surface area. This allows high continuous currents (up to 1500mA) and high pulse currents (up to 3000mA) without the severe initial voltage drop (passivation delay) often observed in bobbin cells under instant load.
3. Can lead wires or connectors be soldered directly onto the battery canister?
   No. Direct soldering onto the stainless steel casing creates localized overheating that can rupture the semi-hermetic seal or degrade internal separators. If your PCB requires direct attachment, select a pre-fitted tabbed variation or an engineered cell holder.
4. How should the Ramway cr17450 lithium battery be stored to maintain its rated capacity?
   Unused batteries should be stored in a clean, dry area at temperatures below 30°C. Under these conditions, the internal self-discharge rate remains below 2% per year, preserving optimal energy reserves over years of storage.
5. Is this cell rechargeable?
   No. The Ramway battery cr17450 is a primary non-rechargeable Li-MnO2 battery. Attempting to charge it introduces severe risks of high internal pressure, thermal runaway, and combustion.
