Industrial high-temperature power

The Tadiran TLH-5903 is an AA 3.6V primary lithium cell built for equipment that must run at 125°C or 257°F. It suits engineers and technicians maintaining down-hole tools, industrial sensors or military kit where ordinary batteries fail.

Upgrade from standard lithium cells

Replace consumer-grade AA lithium batteries when the operating envelope exceeds normal limits and premature replacement costs outweigh the higher unit price. The jump is justified only if the application actually sees sustained temperatures near the rated extreme.

Fits single-cell AA compartments

The cell slots into any standard AA holder without adapters and delivers 3.6V nominal voltage for the full discharge curve. It frees designers from adding thermal shielding or redundant packs, saving board space and assembly time in harsh-environment devices.

Questions about this item

What device or holder fits the Tadiran TLH-5903 AA 3.6V lithium battery?

The Tadiran TLH-5903 uses a standard AA form factor, so it fits any device or holder designed for AA cells.

How is the Tadiran TLH-5903 installed, and what step do people often get wrong?

Insert the battery with the positive terminal facing the direction marked in the device; reversing the polarity is the common mistake that prevents operation.

When will the Tadiran TLH-5903 need replacement in a high-temperature application?

The cell is rated for continuous operation at 125 °C (257 °F); service life depends on the load, but the chemistry is designed for multi-year use in Extended Temperature Series conditions.
