Sokkia SHC-5000 Replacement Battery 3.7V 13600mAh Li-ion

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

This 3.7V 13600mAh (50.32Wh) Li-ion battery replaces the OEM pack in the Sokkia SHC-5000 hand controller. The SHC-5000 is a field data collector used with Sokkia total stations and positioning equipment during topographic surveys and construction layout. It also crosses to part numbers 25260 and 1029732-01.

• SHC-5000 and SHC5000 fitment: Both model designations use the same battery bay, connector pinout, and BMS handshake protocol — this pack covers either variant without modification.
• Bench tested on actual hardware: We ran this pack through the SHC-5000 power-on sequence, active data logging, and a wireless total station communication session. The BMS held stable under the sustained sensor polling current draw without tripping cutoff.
• Pre-deployment calibration cycle: After fitting this battery, run a full calibration cycle through the SHC-5000 instrument menu before heading to site. The unit maps battery state during that routine — skipping it causes premature low-battery warnings on the first real measurement session, even with a full charge in the pack.

BMS cutoff when the SHC-5000 initialises a total station connection

When the SHC-5000 establishes communication with a total station, the radio module and processor both draw peak current simultaneously. A degraded or deeply discharged pack can't sustain that spike, and the BMS trips cutoff to protect the cells. The result looks like a crash or freeze at the connection handshake screen. This replacement pack's higher 13600mAh cell capacity provides enough current headroom to handle that combined initialisation load cleanly.

SHC-5000 won't charge after sitting unused for several months

Extended storage drains Li-ion cells below the BMS recovery threshold — typically around 2.5V per cell — and the BMS enters a sleep state that blocks normal charge input. The charger shows no activity, and the device appears fully dead. To recover, connect the battery to the OEM charger and leave it for 30–60 minutes without interruption; most BMS firmware includes a trickle pre-charge routine that wakes the pack once it detects sustained low-current input. If the pack still shows no response after that window, the cells have dropped below 2.0V and recovery is unlikely — replace the battery.
