X-Rite HHR5 CCD4 Replacement Battery 6V 1800mAh

X-Rite CCD4 / CTP Series — 6V Ni-MH Replacement Battery (HHR5)

This is a 6V 1800mAh Ni-MH replacement for the X-Rite HHR5 battery pack. It fits the CCD4, CCD5, CTP10, and CTP15 spectrophotometers, along with five additional X-Rite models in this measurement instrument family. Voltage and capacity match the original spec exactly.

• CCD and CTP platform fit: These models share the same battery bay dimensions, 6V rail, and connector keying. The BMS handshake on each instrument expects a Ni-MH pack at this voltage — substituting a different chemistry triggers a fault state at power-up.
• Bench tested on actual hardware: We cycled this pack through power-up, probe initialisation, and sustained sensor load on CCD-series hardware. The BMS held charge delivery steady through the initialisation current spike without tripping a cutoff.
• Post-install calibration requirement: After fitting this pack, run a full calibration cycle through the instrument menu before taking any measurements. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings on the first measurement session, even with a fully charged pack.

BMS cutoff when the CCD4 probe module initialises

At power-up, the CCD4 fires current to the probe module before the main measurement loop starts. This initialisation spike is brief but sharp — a weakened original pack can drop voltage fast enough to trigger the BMS cutoff threshold instantly. The instrument either restarts in a loop or throws a battery fault before displaying the home screen. A fresh pack at full charge handles this spike without voltage sag, so the BMS never sees the threshold. If the fault persists after swapping the battery, verify the pack has been charged to at least 6.0V before inserting it.

CCD4 readings drift or reset mid-logging session

Sustained sensor load during a logging session pulls more current than a single spot measurement. An aged Ni-MH pack that reads fine at rest will sag under continuous draw, and the instrument firmware interprets that voltage drop as a low-battery condition and interrupts the session. This shows up as a mid-sequence reset or a string of dropped data points — not a clean shutdown. The fix is a fresh pack with full cell capacity so voltage stays above the instrument's cutoff floor under load. Charge the replacement fully, then confirm the open-circuit voltage reads at or above 6.0V before starting a logging run.
