Care Vision OM-100 Medical Replacement Battery 7.2V 2000mAh

Care Vision OM-100 — 7.2V Ni-MH Replacement Battery (6HP-E200AA-3P)

This 7.2V, 2000mAh Ni-MH battery replaces the OEM pack in the Care Vision OM-100 portable diagnostic device. It matches the original voltage, capacity, and connector spec for direct installation. Intended for clinical environments where continuous device availability matters.

• OM-100 platform fit: The OM-100 runs a single-voltage 7.2V Ni-MH rail with a BMS handshake that validates cell chemistry at power-on. This replacement uses matched Ni-MH cells at the same nominal voltage, so the BMS recognises the pack and clears the charge verification routine without flagging a chemistry mismatch.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a medical-device test rig, monitoring BMS handshake signals and cutoff behaviour. The protection circuit held stable across the full discharge curve, and the pack passed the OEM-equivalent self-test threshold after one full conditioning cycle.
• Post-swap startup protocol: After fitting this battery, let the OM-100 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence flags a false battery fault that persists until the next clean reboot from a fully charged state.

Device not completing boot sequence on new battery

The OM-100 runs a startup self-test that includes a BMS learn cycle. A new cell that has not yet completed one full charge-discharge pass may sit below the BMS confidence threshold during this check, causing the boot sequence to stall or abort. This is not a fault with the battery — it is the device applying a conservative pass criterion to an unconditioned pack. Run one full charge cycle, then power the device on and allow the self-test to complete without interruption before clinical use.

OM-100 will not power on after the battery has been in storage

Ni-MH cells self-discharge during storage at roughly 1–3% per day. A pack that has sat for several weeks can drop below the OM-100's BMS recovery threshold — typically around 5.5V for a 7.2V Ni-MH pack — which causes the device to appear completely dead rather than simply flat. Place the battery on charge for a full uninterrupted cycle before attempting to power on the device. If the charger does not initiate, try a different charger capable of applying a low-current trickle recovery below 0.1C to bring the pack back above the BMS wake threshold of approximately 6.0V.
