Replacement Ni-MH battery pack

This Estry 3SN-2/3AA30-S-J1 replaces the Sanik original in devices that require a 3.6V 600mAh nickel-metal-hydride pack. It is built to the same electrical and mechanical specification as the factory cell. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Overcharge, over-discharge, over-voltage and short-circuit protection are integrated.

Suitable for direct replacement only

It fits equipment designed for the exact 3SN-2/3AA30-S-J1 part number and a 42.57 x 30.2 x 14.43 mm form factor. Buyers needing a different voltage, capacity, chemistry or physical size should look elsewhere. The pack is not rechargeable via USB and cannot be used as a power bank.

3.6V 600mAh Ni-MH chemistry

The single deciding specification is the 3.6 volt 600 milliampere-hour nickel-metal-hydride rating. Only devices specified for this voltage and capacity will operate correctly and safely.

Questions about this item

Does the device I am replacing already use a 3.6 V Ni-MH pack with a 600 mAh rating?

Yes — this replacement is a 3.6 V, 600 mAh Ni-MH pack built to the same 2.16 Wh specification as the original Sanik 3SN-2/3AA30-S-J1 cell.

Will the pack fit in the same compartment as the original 42.57 x 30.2 x 14.43 mm battery?

The dimensions match the original exactly at 42.57 x 30.2 x 14.43 mm and it weighs 77.4 g, so it slots into the existing bay without modification.

How can I confirm the pack is delivering the rated 3.6 V and 600 mAh after installation?

Measure the open-circuit voltage with a multimeter — it should read close to 3.6 V — then run the device through a normal cycle; the run-time should match the original 2.16 Wh capacity.
