When engineers need a battery that can power equipment for years with minimal maintenance, Tadiran is one of the first names that comes to mind. Tadiran batteries are widely used in industrial applications where reliability, long service life, and dependable performance are critical.
At Voltaplex, we offer Tadiran batteries for industrial and OEM applications. While many of the products we carry are primary lithium batteries designed for long-term operation, we also offer rechargeable solutions for applications that require repeated cycling.
This guide explains the differences between the Tadiran batteries available from Voltaplex and how to choose the right one for your application.
What Makes Tadiran Batteries Different?
Tadiran has built its reputation by producing industrial batteries that deliver exceptionally low self-discharge, high energy density, and reliable performance in demanding environments. These characteristics make them a popular choice for remote equipment where battery replacement is difficult or costly.
Many of the Tadiran products available through Voltaplex use lithium thionyl chloride (Li‑SOCl₂) chemistry, a primary (non‑rechargeable) chemistry known for long shelf life and years of dependable service. We also offer the rechargeable Tadiran TLI‑1550A cell for applications that benefit from repeated charging.
Common Applications
Tadiran batteries are commonly used in:
- Utility and smart metering
- Industrial sensors
- Remote monitoring systems
- Security and alarm equipment
- Medical devices
- Asset tracking
- Environmental monitoring
- Industrial instrumentation
Many of these devices are expected to operate unattended for years, making battery selection an important part of the overall system design.
The Tadiran Batteries We Offer
TL Series — Primary Lithium Thionyl Chloride
The Tadiran TL Series of primary lithium batteries consists of non‑rechargeable 3.6 V lithium thionyl chloride batteries available in a range of sizes and capacities. Smaller cells are ideal where space is limited, while larger C-, D-, and DD-size cells provide greater capacity for equipment requiring extended runtime.
TLI‑1550A — Rechargeable Industrial Lithium-Ion
Unlike the TL Series, the TLI‑1550A rechargeable industrial lithium-ion AA cell is designed for repeated charging. It is a good choice for applications with energy harvesting, regular charging, or higher pulse-current demands, such as solar-powered IoT devices and industrial automation.
Questions to Ask Before Selecting a Battery
Before selecting a battery, consider:
- Is the battery rechargeable or primary?
- What is the average current draw?
- Will the device experience short, high-current pulses?
- How many years of service are required?
- What temperatures will the battery experience?
- How much installation space is available?
Common Mistakes
One of the biggest mistakes is choosing a battery based only on capacity. Runtime also depends on current consumption, pulse loads, operating temperature, and the overall system design. Another common mistake is selecting a rechargeable battery when a long-life primary battery would be a better fit — or vice versa.
