China Long Life 3.6V Li-SOCl2 Battery Supplier

Vcell Power is a manufacturer of the 3.6V Li-SOCl2 Battery in China. With over 20 years of manufacturing excellence and a strict quality system (ISO9001, UL, CE), we provide primary lithium-thionyl chloride cells designed for devices demanding extreme longevity and reliability in harsh environments.

How Does the Li-SOCl2 Battery Solve Real Industry Problems?

Engineers face three main issues: voltage lag after storage, failure in extreme temperatures, and short operational lifespans. Here is how our Battery addresses these challenges.

Problem 1: High Self-Discharge Leading to 3-5 Year Replacements

The Customer Need: "Set and forget" for 10+ years.

Our Solution: Ultra-low self-discharge rat.

The Result: A lifespan of up to 10-12 years for automatic meter reading systems, cutting your labor costs by 70%.

Problem 2: Failure in Arctic or Desert Climates

The Customer Need: Reliable startup at -40°C.

Our Solution: Stable electrochemistry with an operating range of -60°C to +85°C.

The Result: Smart water meters in Siberia and oil well sensors in the Sahara run without battery heating pads.

Problem 3: Voltage Delay After Long Idle Periods

The Customer Need: Instant high-pulse activation.

Our Solution: Advanced voltage delay control technology.

The Result: TPMS (Tire Pressure Monitoring Systems) and emergency beacons activate immediately after 5 years of idle storage.

Which Industries Rely on the Battery?

The unique chemistry of the 3.6V Li-SOCl2 Battery (Lithium-Thionyl Chloride) makes it the standard for critical infrastructure.

Utility Metering (Smart Grid): Gas, water, and heat meters (Ultrasonic/Mechanical).

Industrial IoT (IIoT): Wireless sensors, SCADA systems, pipeline monitoring.

Security & Safety: Fire alarm panels, access control systems, GPS beacons.

Medical Electronics: Defibrillators, infusion pumps, and tracking tags.

Automotive: Emergency call systems (eCall) and TPMS.

What Quality Control Does Your Battery Undergo?

Frequently Asked Questions

Q1: Is the  Li-SOCl2 Battery rechargeable? No. This is a primary (non-rechargeable) lithium battery. It is designed for long-term, low-drain applications where recharging is impossible (e.g., embedded in a gas meter). Attempting to recharge it is dangerous.

Q2: Can I replace my  Li-SOCl2 Battery with a standard AA alkaline? No. Alkaline batteries provide 1.5V and leak over time. You need two alkalines in series (3.0V) with a shorter lifespan. Our 3.6V Li-SOCl2 Battery (ER14505) matches the AA form factor but provides higher voltage (3.6V) and 10x the shelf life.

Q3: Does Vcell Power add a BMS to the Battery? For single cells, a BMS is not required. However, if you need a battery pack (e.g., 7.2V or 10.8V) assembled with these cells, we can integrate a protection circuit (PCM/BMS) against over-discharge and short circuits.

Q4: Do you have stock in Europe or the USA? We ship directly from our factories in Guangdong, Henan, Jiangxi, and Shandong. With express shipping (5-7 days), we are as fast as local warehouses but with lower factory-direct prices.

Q5: What is the maximum pulse current for the ER18505 3.6V Li-SOCl2 Battery? While the max continuous current is 100mA, the ER18505 can support pulses up to 200mA for short durations (0.1 seconds). For high-power pulses, please consult our engineering team for the correct bobbin-type cell selection.
