Sokkia SHC-5000 Compatible Battery 3.7V 10400mAh Li-ion

Sokkia SHC-5000 — 3.7V Li-ion Replacement Battery (1013591-01)

This 3.7V 10400mAh (38.48Wh) Li-ion battery is a direct replacement for the Sokkia SHC-5000 handheld field controller. The SHC-5000 is a surveying data collector used with total stations and GNSS receivers on construction and geomatics sites. OEM part numbers covered: 1013591-01, 25260, and 1029732-01.

• SHC-5000 and SHC5000 fit: Both model designations reference the same hardware platform — identical voltage rail, connector pinout, and BMS handshake protocol. One battery covers both.
• Bench tested on actual hardware: We cycled this pack through the SHC-5000's communication workflows — active GPS polling, Bluetooth data link, and sustained screen-on logging. The BMS held stable under combined draw without tripping cutoff.
• Post-install calibration step: After fitting this battery, run a full calibration cycle through the SHC-5000's system menu before heading into the field. The controller maps battery state during that process. Skip it, and the low-battery warning will trigger well ahead of actual depletion on the first session.

BMS cutoff when the SHC-5000 initialises a connected instrument

When the SHC-5000 powers up a connected total station or GNSS receiver over its data port, the initialisation handshake pulls a brief current spike. A degraded or deeply discharged replacement pack can read this spike as an overcurrent event and trip the BMS cutoff. This causes the controller to shut off within seconds of instrument connection — not at startup itself. The fix is to charge the pack to full before the first connected session, so cell voltage is high enough that the BMS threshold isn't marginal when the spike hits.

SHC-5000 shows erratic battery percentage after swapping packs

The SHC-5000's charge indicator is calibrated to the voltage curve of the installed pack. Swapping in a new cell with a different resting voltage shifts the reference point the controller uses to estimate remaining charge. This shows up as sudden jumps — 80% dropping to 20% in minutes, or the display reading full when the battery is partially depleted. Running one complete discharge-to-recharge cycle through the controller normalises the voltage mapping. After that cycle, percentage readings stabilise to within a few percent of actual state.
