Ni-MH replacement cell

The Estry TN-61 is a single nickel-metal-hydride battery rated at 3.6V and 600mAh. It matches the original manufacturer specifications and includes overcharge, over-discharge, over-voltage and short-circuit protection. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. Dimensions are 42.57 x 30.2 x 14.43mm with a weight of 77.4g.

Compatibility and limits

This pack suits devices that list the TN-61 as the exact part number. It will not work for equipment requiring a different voltage, capacity, chemistry or physical size. Buyers who need a multi-cell pack, a higher watt-hour rating or an alternative connector should look at other options.

Deciding specification

The critical figure is the 2.16Wh energy rating derived from 3.6V and 600mAh; if the original battery shows a different watt-hour value this cell is not a direct replacement.

Questions about this item

Will the TN-61 3.6V 600mAh Ni-MH battery fit the same compartment as my original TN-61 pack?

Yes, the replacement matches the original TN-61 dimensions of 42.57 x 30.2 x 14.43 mm and weighs 77.4 g, so it seats in the existing bay without modification.

How can I verify the TN-61 battery is performing to its 2.16 Wh rating after installation?

Measure the pack voltage with a multimeter; a healthy cell reads near 3.6 V under light load, and the device should run for the expected duration based on 600 mAh capacity.

Does the TN-61 single-pack include a charger or only the 600 mAh Ni-MH cell?

The box contains one TN-61 3.6 V 600 mAh Ni-MH battery; a compatible charger is not included and must be purchased separately.
