Critical capacity and voltage match

The cell delivers exactly 600mAh at 1.2V for 0.72Wh, matching the original specification. Any deviation in capacity or voltage will cause incorrect runtime or charging behaviour in the target devices.

Questions about this item

Will the 35.5 x 16.6 x 6.8 mm dimensions fit the battery compartment of my NW-MS70D without modification?

The replacement is built to the original specifications for the NW-MS70D and NW-MS90D, so the 35.5 x 16.6 x 6.8 mm form factor matches the factory compartment exactly.

How can I verify the 1.2 V 600 mAh cell is delivering the rated 0.72 Wh after installation?

Charge the pack fully, then measure the terminal voltage under a known load; a healthy Ni-MH cell will hold close to 1.2 V and sustain the expected runtime for the device.

Does the package include a charger or only the 38.2 g battery pack?

Only the battery pack is supplied; a compatible Ni-MH charger must be purchased separately if you do not already have one.
