Photographers Using Compatible Metz Flashes

The cell suits owners of the listed Metz flash units who need a direct-fit replacement with the same voltage and connector layout. It is not intended for cameras or lights that require a different voltage, capacity or physical footprint. Buyers who need a higher energy rating or a different chemistry should look elsewhere.

Voltage and Capacity Match the Original Spec

The decisive figure is the 6.0 V / 4200 mAh rating, which must match the flash unit's original specification. If the device demands a different voltage or a significantly different milliampere-hour value, this pack will not operate correctly. Confirm the model number before ordering.

Questions about this item

Does the Estry 9745 arrive ready to use or does it need a separate charger?

The battery ships as a single 6.0 V 4200 mAh Ni-MH pack weighing 405.0 g; a compatible charger is not included and must be purchased separately.

The specs show both 4200 mAh and 4500 mAh — which capacity should I trust for the 9745 replacement?

The headline rating for this model is 4200 mAh at 6.0 V delivering 25.2 Wh; the 4500 mAh figure appears in a generic spec line and does not apply to the 9745 pack.

What runtime can I expect from the 25.2 Wh rating when the pack powers a Metz flash unit?

At 6.0 V the 25.2 Wh capacity equals 4200 mAh, so a Metz flash drawing 2 A would run for roughly two hours before the pack needs recharging.
