ADE DP2400 Medical Scale Replacement Battery 7.2V 2000mAh

ADE DP2400 / DP2300 / MS-2510 — 7.2V Ni-MH Replacement Battery (MZ50010-001)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the ADE DP2400, DP2300, and MS-2510 portable medical scales. It matches the OEM part number MZ50010-001 and fits directly into the original battery compartment. If your device is losing charge faster than expected or failing to hold a reading through a full session, the cell has degraded and needs replacing.

• DP2400, DP2300, and MS-2510 compatibility: These three models share the same 7.2V battery rail, connector pinout, and BMS communication protocol — which is why they all use MZ50010-001. Swapping between models is not required, but the electrical and physical fit is identical across the range.
• Bench tested on actual hardware: We ran this cell through the DP2400 charge cycle and monitored BMS handshake at startup. The charge IC accepted the new cell without fault flags, and the self-test sequence completed clean on the second full charge cycle.
• Post-installation self-test protocol: After fitting this battery, allow the device to complete its full power-on self-test without interruption. The ADE BMS runs a chemistry verification at startup — cutting power mid-sequence can latch a false battery fault that persists until the next clean reboot.

Why the DP2400 shows a low battery alarm immediately after a confirmed full charge

The ADE BMS uses a voltage threshold calibrated to an aged OEM cell, not a fresh one. A new Ni-MH cell has a slightly different resting voltage curve during the first few cycles, which can read below the alarm threshold even when fully charged. This is not a fault with the battery — it is the BMS learning the new cell's profile. Run one complete charge-discharge cycle and the alarm clears on its own. Resting voltage after a full charge should stabilise above 8.4V before the BMS stops flagging.

Device will not power on after battery was left sitting in storage

Ni-MH cells self-discharge at roughly 1–3% per day at room temperature. If the battery sat unused for several weeks, the cell voltage may have dropped below the BMS recovery threshold — typically around 5.4V for a 7.2V pack — and the device refuses to boot as a protection measure. Connect the charger and leave it for a minimum of 4 hours before attempting to power on. If the charge indicator does not respond within 30 minutes, check the charger output voltage is delivering at least 8.4V at the connector.
