Spectra Precision SP60 GNSS Replacement Battery 7.4V 2000mAh

Spectra Precision SP60 / SP80 GNSS — 7.4V Li-ion Replacement Battery

This 7.4V 2000mAh (14.8Wh) Li-ion battery fits the Spectra Precision SP60 and SP80 GNSS receivers. Both are high-precision satellite positioning instruments used in surveying, construction, and mapping. The SP60 and SP80 share the same battery bay dimensions and voltage rail, making this a direct fit for either unit.

• SP60 and SP80 compatibility: Both receivers run on the same 7.4V two-cell Li-ion architecture with an identical physical footprint — 70.60 × 38.60 × 20.54mm. The BMS handshake protocol and connector pinout match across both platforms, so the same pack works in either receiver without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge under simulated GNSS tracking load. The BMS held stable across sustained satellite acquisition draw, and cell voltage balanced correctly at the top-of-charge cutoff of 8.4V.
• First-use calibration step: After installing this pack, run a full calibration cycle through the SP60 or SP80 system menu before heading into the field. The receiver maps battery state during that calibration pass — skipping it causes premature low-battery warnings during your first measurement session.

SP60 shutting down during satellite lock acquisition

The SP60's GNSS engine draws a short current spike when acquiring and locking onto satellite constellations, particularly during cold starts with multiple systems active (GPS, GLONASS, BeiDou). An aged or partially discharged cell can't sustain the brief peak, and the BMS trips the output to protect the cells. This shows up as a shutdown right at the moment the receiver would normally confirm lock — not a random cutoff. A fresh, fully charged pack resolves this; charge to 8.4V before any session that starts with a cold acquisition.

Receiver display showing erratic battery percentage after pack swap

When you swap in a new pack, the SP60 and SP80 voltage-threshold indicator has no baseline history for the new cells, so it recalibrates across the first few charge and discharge cycles. This causes the percentage readout to jump or display an unexpectedly low figure even on a fully charged pack. It is not a fault — the receiver is building a discharge curve reference for the new battery. Run two to three full charge and discharge cycles through the instrument menu, and the percentage readout will stabilise.
