About this replacement
X-Rite SP60 / SP62 / SP64 — 7.2V Ni-MH Replacement Battery (SP62-79-23)
This is a 7.2V, 2000mAh Ni-MH replacement battery for the X-Rite SP60, SP62, and SP64 portable spectrophotometers. It replaces OEM part SP62-79-23. These instruments are used in colour measurement and quality control across print, textile, and manufacturing environments where a dead battery means a halted workflow.
- SP60, SP62, and SP64 compatibility: All three models share the same battery bay dimensions, connector pinout, and 7.2V nominal voltage rail. The BMS handshake protocol is identical across the series, so one cell pack covers all three without modification.
- Bench tested on actual hardware: We cycled this pack through the SP60's power-on sequence, probe initialisation, and sustained measurement logging. The BMS held stable across the current spike at sensor wake-up and did not trip during back-to-back measurement cycles.
- Post-install calibration step: After fitting this battery, run a full calibration cycle through the instrument menu before taking it into the field. The SP60 maps battery state during calibration — skipping this causes premature low-battery warnings to appear during your first measurement session even when the pack is fully charged.
BMS lockout after the SP60 sat unused in a carry case for months
Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. After several months unused, the pack can drop below the BMS recovery threshold — typically around 5.4V for a 7.2V Ni-MH pack — and the BMS enters a sleep state. When this happens, the charger shows no activity and the instrument does not power on. Place the battery in the charger for a full uninterrupted charge cycle of at least 12 hours before attempting to power the SP60. If the charger LED does not respond within 30 minutes, remove and reinsert the pack to trigger the BMS wake-up pulse.
SP60 shuts down mid-measurement despite the battery showing charged
This is a voltage sag issue, not a capacity issue. When the SP60's optical sensor and motor fire simultaneously during a measurement, the instantaneous current draw spikes sharply. An aged or partially discharged cell cannot hold voltage above the instrument's cutoff threshold during that spike, so the SP60 interprets it as a depleted pack and shuts off. A fresh, fully charged cell handles this spike without dropping below the 6.0V cutoff. Charge the pack fully, run the calibration cycle, and retest — if shutdown still occurs, the original cell has likely degraded beyond recovery.
