Description

The Tadiran TL-5135/P 3.6V 1/6D 1.7Ah Lithium Battery with PC Pins delivers dependable, long-lasting power for industrial electronics, memory backup systems, programmable controllers, and specialized electronic equipment. Manufactured by Tadiran, this industrial-grade primary lithium battery features lithium thionyl chloride (Li-SOCl2) chemistry, providing a rated voltage of 3.6 volts and a nominal capacity of 1700mAh (1.7Ah) under specified discharge conditions. Its stable operating voltage, low self-discharge characteristics, and high energy density make it particularly suitable for low-current applications requiring reliable operation over extended periods.

The Tadiran TL-5135/P features a compact 1/6D wafer-style design measuring approximately 32.9mm in maximum diameter, with a low-profile body and three factory-installed PC pins for printed circuit board mounting. The battery weighs approximately 21.5 grams and operates across a wide temperature range of -55°C to +85°C, making it suitable for compatible industrial and electronic systems exposed to demanding environmental conditions. Designed primarily for memory retention and low-drain standby applications, this non-rechargeable battery provides a practical replacement solution for equipment specifically requiring the TL-5135/P configuration. This product includes one genuine Tadiran TL-5135/P 3.6V lithium battery with three PCB mounting pins.

Important Compatibility Note:

• Verify that your equipment specifically requires a Tadiran TL-5135/P 3.6V lithium battery with three PC pins before installation.
• DIMENSIONS: The battery has a maximum diameter of 32.9mm. The low-profile body is approximately 10.2–11.4mm high depending on the measurement reference. PCB pins extend beyond the battery body.
• The TL-5135/P uses a three-pin PCB mounting arrangement. Confirm pin spacing, orientation, polarity, and circuit board clearance against the original battery and manufacturer's dimensional drawing.
• Other Tadiran TL-5135 versions may have different terminal configurations and are not automatically interchangeable with the /P version.
• Although other 1/6D lithium batteries may share similar dimensions, their voltage, chemistry, discharge characteristics, and terminals may differ.
• These batteries are designed primarily for low-current, long-duration applications. Confirm the equipment's continuous and pulse-current requirements before replacement.
• Lithium thionyl chloride batteries can develop voltage delay after prolonged storage or low-current operation. Confirm suitability for applications requiring immediate high-current pulses.
• These batteries are non-rechargeable primary lithium cells. Never attempt to recharge them.
• Do not install the battery in circuits that apply charging current unless appropriate manufacturer-approved blocking and protection measures are incorporated.
• Use suitable PCB installation procedures and avoid excessive heat exposure during soldering.
• Always verify the positive (+) and negative (-) terminal positions before installation.
• Do not mix different battery models, chemistries, ages, or states of discharge in the same battery assembly.
• Do not short-circuit, crush, puncture, disassemble, heat, or expose the battery to fire.
• Lithium thionyl chloride batteries contain a corrosive electrolyte. Do not handle leaking or damaged batteries without appropriate safety precautions.
• Store batteries in a clean, cool, dry, ventilated location at temperatures not exceeding +30°C.
• Keep batteries away from children and pets.
• Follow applicable lithium battery transportation, recycling, and disposal requirements.
