Ni-MH replacement battery

The Estry TR-3 is a nickel-metal hydride replacement cell built to match the original equipment specifications for TriLithic TR-3 and TR3 devices. It delivers a nominal 3.6V and a rated capacity of 2500mAh, providing 9.0Wh of energy in a pack measuring 50.94 x 43.7 x 15.0mm and weighing 80.0g. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Who this suits and who should look elsewhere

This cell suits technicians and operators who need a direct drop-in power source for compatible TriLithic handheld analysers or meters. It is not for users whose equipment requires a different voltage, chemistry, form factor or connector layout; buyers needing higher capacity or a different cell size should seek an alternative part.

Deciding specification: 3.6V 2500mAh Ni-MH chemistry

The single specification that determines fit is the 3.6V 2500mAh nickel-metal-hydride chemistry in the stated 50.94 x 43.7 x 15.0mm housing. Only devices designed for this exact voltage, capacity and physical profile will operate correctly and safely with this replacement pack.

Questions about this item

How long will the 2500mAh capacity last under continuous load before voltage drops?

The 9.0Wh energy rating at 3.6V supports the rated 2500mAh capacity; actual runtime depends on the discharge current of the device it powers.

Does the pack generate noticeable heat or require cooling during all-day operation?

Ni-MH chemistry with built-in overcharge, over-discharge and short-circuit protection limits heat rise; the compact 50.94 x 43.7 x 15.0mm size has no active cooling.

What device or connector must I already have for this TR-3 pack to work?

It is a direct replacement for Trilithic TR-3 and TR3 equipment; confirm the original battery part number matches before installing.
