ER34615 Lithium Thionyl Chloride Battery Product Description

Product Overview

The ER34615 is a high-performance lithium thionyl chloride (Li-SOCl₂) primary battery. It features a fully sealed stainless steel cylindrical casing with dimensions of 34 mm in diameter and 61.5 mm in height, also known as a D-type or size 1 battery. Renowned for its exceptional performance and reliability, this battery serves as an ideal power solution for industrial instrumentation, smart metering, remote monitoring, and other demanding applications.

Core Technical Specifications

Basic Electrical Characteristics:
  • Nominal Voltage: 3.6V (Open Circuit Voltage: 3.66V)
  • Rated Capacity: 19,000mAh (19Ah)
  • Maximum Continuous Discharge Current: 230mA
  • Maximum Pulse Current: 400mA
  • Cut-off Voltage: 2.0V
Physical Characteristics:
  • Dimensions: Φ34.0 × 61.5mm
  • Approximate Weight: 107g
  • Operating Temperature Range: -55℃ to +85℃ (some models can operate from -60℃ to +85℃)
  • Annual Self-Discharge Rate: ≤1%
  • Shelf Life: Over 10 years

Key Features & Advantages

High Energy Density: With a specific energy of up to 430Wh/kg or 1080Wh/L, it offers extended runtime in a compact size. Over 90% of its capacity is delivered on a high voltage plateau with minimal voltage decay.
Broad Temperature Performance: Capable of reliable operation in extreme temperatures from -55℃ to +85℃. It retains approximately 50% of its nominal capacity at -60℃, demonstrating excellent adaptability to both high and low temperatures.
Ultra-Long Life & Low Self-Discharge: The formation of a protective LiCl film (passivation layer) between the lithium anode and the thionyl chloride electrolyte contributes to an exceptionally low self-discharge rate of less than 1% per year. It offers a shelf life exceeding 10 years at room temperature, with some manufacturers claiming up to 15-20 years.
Safety & Reliability: The fully sealed stainless steel casing ensures integrity through hermetic welding. Internal safety features such as venting grooves, fuses, or PTC devices are incorporated to prevent over-pressure and short-circuit risks. It is free of hazardous heavy metals like mercury, cadmium, and lead, meeting environmental requirements.

Product Series

The ER34615 series includes three variants:
  • ER34615 (Standard Capacity): Standard model with 19Ah capacity, suitable for low to medium discharge rate applications.
  • ER34615M (High Power): Offers 14.5Ah capacity with a maximum continuous discharge current of 2000mA and pulse current of 3000mA. Ideal for high-current output and low-temperature operation.

Important Usage Notes

  1. Non-Rechargeable: The ER34615 is a primary (non-rechargeable) lithium battery. Charging is strictly prohibited​ as it may cause explosion or fire.
  2. Prevent Short Circuits: Avoid direct contact between the positive and negative terminals.
  3. Correct Installation: Install the battery according to the correct polarity as specified by the device.
  4. Avoid High Temperatures: Store at a maximum temperature of 30℃. Do not expose to heat or incinerate.
  5. Transportation Regulations: As the internal lithium content exceeds 1 gram, transportation must comply with Dangerous Goods Safety Regulations.
With its high energy density, wide operating temperature range, ultra-long life, and reliable performance, the ER34615 battery is the preferred power solution for industrial-grade applications, providing durable and stable power support for various smart devices and remote monitoring systems.
