Fanso ER14250H 3,6V 1200mA battery

Fanso ER14250H 3.6 V lithium battery

🔋 The Fanso ER14250H is an industrial primary lithium cell based on Li-SOCl₂ lithium-thionyl chloride chemistry.

It provides a nominal voltage of 3.6 V, a nominal capacity of 1200 mAh and a compact 1/2 AA cylindrical format.

⚠️ Non-rechargeable cell

Do not recharge the Fanso ER14250H. It is a primary disposable battery, not a rechargeable lithium-ion cell.

Charging, short-circuiting, overheating or damaging the enclosure can result in leakage, overheating or cell rupture.

📏 1/2 AA dimensions

• diameter — approximately 14.5 mm;
• length — approximately 25.4 mm;
• nominal voltage — 3.6 V;
• nominal capacity — 1200 mAh.

Although its diameter is similar to a standard AA cell, its length and voltage are different. It is not a substitute for ordinary AA or AAA batteries.

🧪 Li-SOCl₂ chemistry

Lithium-thionyl chloride cells provide high energy density, stable operating voltage and low self-discharge.

They are particularly suitable for equipment that remains in standby for long periods and performs measurements or data transmission only occasionally.

⏳ Long-term autonomous operation

Actual service life depends on:

• continuous current consumption;
• data-transmission frequency;
• pulse-current demand;
• ambient temperature;
• the device’s cut-off voltage;
• contact quality;
• storage conditions before installation.

📊 Intended for low continuous loads

The ER14250H is a bobbin-type cell intended primarily for low and stable current consumption.

Devices with high short-duration current pulses, such as GSM, GPRS, NB-IoT or radio transmitters, may require a pulse capacitor, SPC hybrid capacitor or a different battery configuration.

🏭 Applications

• water meters;
• gas meters;
• heat meters;
• electronic correctors;
• industrial sensors;
• security systems;
• controller memory backup;
• telemetry systems;
• measuring equipment;
• IoT devices.

🔌 Terminal options

The Fanso ER14250H may be supplied:

• as a standard cylindrical cell;
• with solder tabs;
• with axial leads;
• with wires;
• with a fitted connector;
• as part of a battery pack.

Verify the wire arrangement, connector type and polarity against the original battery before ordering.

✅ Key advantages

• 3.6 V nominal voltage;
• 1200 mAh capacity;
• compact 1/2 AA size;
• low self-discharge;
• stable operating voltage;
• high energy density;
• suitable for long-term autonomous use;
• widely used in meters and industrial sensors.

⚠️ Safety instructions

• do not recharge;
• do not short-circuit;
• do not disassemble or puncture;
• do not expose to fire;
• do not overheat;
• do not reverse polarity;
• do not use a damaged cell;
• keep away from children;
• dispose of it as a lithium chemical cell.

⚠️ Confirm before ordering

• whether a bare cell or battery pack is required;
• solder-tab configuration;
• wire and connector type;
• wire length;
• connector polarity;
• continuous-current requirement;
• maximum pulse-current requirement;
• operating-temperature range;
• compatibility with the exact meter or controller;
• manufacturing date.

💡 Important: matching only the 3.6 V marking is not sufficient. The chemistry, dimensions, load current, terminals, connector and polarity must also match the original battery.
