Replacement Ni-MH battery

The Estry 306 is a nickel-metal hydride cell rated at 3.6 volts and 600 milliampere-hours. It is built as a direct replacement for the original Zenith 306 battery pack. The single-unit pack supplies 2.16 watt-hours and includes overcharge, over-discharge, over-voltage and short-circuit protection. It is intended for users who need a new drop-in cell for compatible equipment.

Who this suits and who it does not

The cell fits devices that specify the 306 model and require a 3.6 V Ni-MH pack with the listed capacity. Buyers whose hardware calls for a different voltage, chemistry or form factor should look elsewhere. Anyone needing a multi-cell pack or a higher capacity than 600 mAh will not be served by this item.

Critical specification

The decisive figure is the 3.6 V, 600 mAh Ni-MH rating in the 42.57 x 30.2 x 14.43 mm form factor. Matching this voltage, capacity, chemistry and physical size determines whether the battery will work in the target device.

Questions about this item

Should I choose the 600mAh version or a different capacity for model 306?

The 600mAh pack is the only capacity listed for the Estry 306 replacement, matching the original specification exactly.

What does the 3.6V 600mAh rating deliver in actual use?

It provides 2.16Wh of energy, giving the same voltage and runtime as the original Zenith 306 battery in compatible devices.

Does the Ni-MH chemistry limit charging speed or require a special charger?

Ni-MH cells accept standard constant-current charging; the built-in protection circuit guards against overcharge, over-discharge and short circuits.
