Product Description
When your industrial equipment, programmable logic controller, or embedded system needs reliable long-term power, the Electrochem QTC 85PC3 delivers. This lithium wafer cell — also known as the 3B880 — is a go-to solution for engineers and technicians who need a dependable board-mountable battery that holds up in demanding environments.
Built for Industrial and Memory Backup Applications
The QTC 85PC3 is a 3.6-volt, 1,000mAh lithium thionyl chloride (LiSOCl₂) cell engineered for long-life, low-drain applications. It's commonly used as a memory backup source in programmable logic controllers (PLCs), CMOS/BIOS settings retention, industrial meters, animal telemetry equipment, and downhole oil and gas instrumentation. If your equipment needs a battery that can quietly do its job for years without attention, this is it.
Flexible Installation
The QTC 85PC3 features three PC pins, giving you two installation options: the cell can be soldered directly to a circuit board or plugged into a compatible socket. This flexibility makes it a natural fit for OEM designs and field replacements alike.
Long Shelf Life and Stable Performance
With a self-discharge rate of just 3% per year, this battery holds onto its charge even during extended storage — giving it a shelf life of up to 10 years. That's a major advantage for spare parts inventories or low-cycle applications where the battery may sit for months before it's ever put to work.
The stable voltage output and wide operating temperature range of -40°F to +185°F make it well-suited for use in environments where temperature swings are a concern, from cold storage facilities to high-heat industrial settings.
Compatible Devices
This battery is a direct replacement in a wide range of equipment, including:
- Cutler Hammer D126AS Programmable Logic Controller
- Ziatech ZT88CT08, ZT88CT25, and ZTE8901 embedded computers
- Graco Oil Meters
- SRM Pro, Amateur, and Dura Ace cycle power meters
- Various industrial PLC, CMOS/BIOS, medical backup, and telemetry devices
Made in the USA
Assembled in the USA, the QTC 85PC3 is manufactured to tight tolerances using bobbin-style construction with a stainless steel container and hermetic glass-to-metal sealing — the kind of build quality you'd expect from a battery designed for critical industrial use.
Frequently Asked Questions
What devices use the Electrochem QTC 85PC3 (3B880) battery?
A: This battery is commonly used in Cutler Hammer D126AS programmable logic controllers, Ziatech embedded computers (ZT88CT08, ZT88CT25, ZTE8901), Graco oil meters, SRM cycle power meters, and a variety of other industrial PLC, CMOS/BIOS, medical backup, and telemetry applications.
Is the QTC 85PC3 rechargeable?
A: No. This is a primary (non-rechargeable) lithium thionyl chloride battery. It should be replaced when discharged — attempting to recharge it is unsafe.
How is this battery installed?
A: The QTC 85PC3 has three PC pins that allow it to be either soldered directly onto a circuit board or inserted into a compatible socket. Always refer to your equipment's documentation to confirm the correct installation method.
What is the shelf life of this battery?
A: The QTC 85PC3 has a shelf life of up to 10 years, thanks to its very low self-discharge rate of approximately 3% per year at room temperature. It's a great battery to keep on hand as a spare.
What part numbers does this battery replace?
A: This battery is a direct replacement for Cutler Hammer 34-1054, Interstate LIT2730, and Electrochem part numbers 3B0880, 3B6880, QTC85, QTC85-3B0880, QTC85-3B6880, QTC85-3B880, QTC85 PC, and QTC85 PC3, among others.
What temperature range can this battery handle?
A: The QTC 85PC3 is rated for use between -40°F and +185°F, making it a reliable choice for both cold and high-heat industrial settings.
