Replacement battery for Sony MiniDisc players

The Estry D-EJ825 is a 1.2V 1200mAh Ni-MH pack built to match the original specifications for a long list of portable MiniDisc recorders and players. It fits models such as the D-EJ825, MZ-55, MZ-75, MZ-R501, MZ-E700, MZ-E501, MZ-E10, MZ-E600, MZ-E70, MZ-E75 and D-EJ1000. The cell also replaces part numbers NH-9WM, NH-14WM, NH-10WM, NC-5WM, NC-6WM and NC-4WM.

Capacity and daily headroom

Rated at 1200mAh and 1.44Wh, the pack delivers enough energy for extended playback or recording sessions on a single charge. It powers the listed devices through typical daily use without needing a mid-day top-up. The capacity is fixed at 1200mAh, so users needing longer runtimes between charges will find the limit here.

Build, safety and day-to-day fit

The battery measures 66.78 x 16.7 x 5.96mm and weighs 50.0g, matching the original form factor for a direct fit. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications and includes overcharge, over-discharge, over-voltage and short-circuit protection. Buyers with non-listed MiniDisc models or devices requiring a different voltage or connector will need a different pack.

Questions about this item

Will the 1.2V 1200mAh Ni-MH pack fit my MZ-E700 without modification?

Yes, the pack is listed as compatible with the MZ-E700 and matches the original NH-10WM dimensions of 66.78 x 16.7 x 5.96mm.

How do I confirm the 1.44Wh cell is charging correctly after installation?

The device should show a full charge indicator within the normal charge cycle and deliver expected playback time without overheating.

Does the box include a charger or only the 50.0g battery?

Only the replacement battery is supplied; a compatible charger must be purchased separately.
