Direct replacement

The Estry 2/3AAA pack delivers 3.6V and 300mAh in a three-cell arrangement. It matches the original dimensions of 30.38 x 31.37 x 10.63mm and weighs 47.0g. Buyers who need a different voltage or a higher capacity pack cannot use this model.

Sustained output

The nickel-metal hydride chemistry provides steady current without the voltage sag common in short bursts. Overcharge, over-discharge, over-voltage and short-circuit protection circuits maintain stable operation through repeated cycles. The 1.08Wh rating reflects consistent energy delivery over the rated lifespan.

Thermals and draw

Normal charging and discharging stay within the certified safety limits of ISO9001, RoHS, CE, UN38.3 and MSDS. No active cooling is required and the pack runs silently in typical devices. Self-discharge is low for Ni-MH, preserving stored energy during standby periods.

Questions about this item

Does the 3.6 V, 300 mAh Ni-MH pack generate noticeable heat when left on charge all day?

The 1.08 Wh cell is designed for low self-discharge and includes over-charge and over-voltage protection, so it stays cool during continuous trickle charging.

What device connector must I already have for this 30.38 × 31.37 × 10.63 mm pack to fit?

It replaces a 2/3AAA × 3 battery assembly, so your device needs the matching three-cell holder or solder tabs for that form factor.

Will the 47.0 g pack work in older equipment that originally used 2/3AAA × 3 cells?

Yes, it matches the original voltage, capacity and dimensions, and carries ISO9001, RoHS, CE and UN38.3 certification for drop-in compatibility.
