This OEM-spec BDC58 / BDC70 lithium battery packs solve power supply failures for modern Sokkia robotic & reflectorless total stations: inferior imitation cells lacking multi-layer safety PCB lead to overheating, swelling and capacity rapid decay, corroded gold-plated contact shrapnel trigger intermittent power dropout, mismatched third-party packs cause instrument unrecognition and mainboard voltage fluctuation, aged original batteries drastically cut all-day field runtime, loose lock buckle leads to power interruption during bumpy mountain transport. Standard 7.2V low self-discharge lithium cell group with built-in 5-fold safety protection circuit, perfectly match original Sokkia high-end robotic survey instrument power management system, deliver stable long-duration power supply for highway control network layout, open-pit mine automated monitoring, tunnel long-term deformation observation and large-area rural cadastral mapping projects.

Product Overview

The Sokkia BDC58 and BDC70 dedicated lithium-ion battery packs are interchangeable high-capacity power modules separately customized for two mainstream Sokkia instrument platforms, zero memory effect and ultra-low self-discharge for long seasonal idle storage.
1. BDC58 Integrated Structure: 4400mAh high-density lithium core, auto-reset overcharge/over-discharge/overcurrent/short-circuit/over-temperature five-fold safety PCB, dual large-area gold-plated elastic contacts, matte black impact-resistant ABS shell, built-in positioning lock buckle, internal battery communication identification chip for SRX robotic series recognition.
2. BDC70 Integrated Structure: Upgraded 5240mAh large-capacity lithium core, same full safety protection circuit as BDC58, thickened anti-drop ABS outer casing, optimized contact spacing for CX/FX mid-high end reflectorless total stations, built-in battery data communication chip to display real-time remaining power on instrument touch screen.
Both models adopt double-sided thick gold-plated conductive terminals, resist mud, rainwater and underground tunnel damp corrosion, maintain stable high-current continuous output during long-time robotic automatic tracking measurement. Hard UV stabilized ABS shell anti-brittle at -20℃ low-temperature plateau construction, no permanent deformation after backpack extrusion and rock collision. Independent multi-protection circuit automatically cut off input/output under abnormal charging/discharging conditions, fully protect expensive robotic total station mainboard, ATR tracking module and multi-frequency angle encoder from burnout damage. Direct plug-and-play installation without wiring modification, unified compatible with CDC68 single-slot & dual-slot dedicated lithium chargers for standardized safe charging.

Core Advantages & Practical Structural Design

• 100% OEM shell dimension, contact layout, lock buckle structure, 7.2V nominal voltage and internal communication chip protocol fully consistent with factory original BDC58/BDC70 batteries, direct drop-in replacement for aged, bulging, short-runtime unrecognizable original packs
• Dual capacity tier design: BDC58 4400mAh for SRX robotic stations, BDC70 upgraded 5240mAh for CX/FX reflectorless series, extend continuous field working time up to 14 hours for full-day automatic stakeout and monitoring
• Built-in five-fold auto-reset safety protection PCB, comprehensive protection against overcharge, over-discharge, overcurrent, short-circuit and overheating, eliminate field misoperation induced battery swelling and instrument mainboard burnout risk
• Dual large-area thick gold-plated elastic contact shrapnel, anti-rust anti-oxidation, completely solve intermittent power failure faults caused by mine/tunnel mud, dust and slurry adhesion on contact surfaces
• Integrated molded anti-loose positioning lock buckle, tightly clamped inside instrument battery compartment without shaking, avoid sudden power cut during vehicle transport vibration and continuous robotic tracking operation
• Matte black full UV anti-aging ABS shell, scratch-resistant and easy to wipe surface dirt; wide operating temperature range -20℃~+60℃, adapt all-weather plateau, mine, tunnel and open-air construction environments
• Unified charger compatibility: both BDC58 & BDC70 fully match CDC68 single/dual slot dedicated lithium chargers, cross-series interchangeable power accessory for mixed Sokkia instrument fleets
• Classified exclusive instrument matching: BDC58 fits SRX robotic / SET-X / SDL1X digital level; BDC70 fits CX / FX / RX-350 mid-high reflectorless total stations, coordinate with A00456 GPS-PDL composite cable and full PDL radio accessory set
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Compact rectangular integrated battery body, lightweight easy classified storage in maintenance tool pouch alongside CDC68 chargers, iM52/iM55 silicone keyboard mats and survey optical mechanical spare parts

Sokkia SRX/CX/FX Series Total Station Field Power Maintenance & Survey Application Scenarios

Necessary original high-capacity power maintenance spare part for rural large-area cadastral boundary mapping, residential building automatic layout stakeout, municipal pipeline control network measurement, open-pit mine unmanned robotic monitoring and long-term bridge/tunnel foundation deformation monitoring Sokkia survey instrument projects. When original BDC58/BDC70 lithium battery has obvious runtime attenuation, shell bulging, instrument unrecognition or poor-contact sudden power failure, survey maintenance technicians directly replace the corresponding model OEM battery pack to restore stable all-day uninterrupted high-current power supply, prevent frequent shutdown interrupting robotic ATR automatic tracking and long-distance reflectorless ranging measurement data recording. Built-in five-layer safety protection circuit effectively reduce battery scrap rate and field sudden power failure risk; low self-discharge lithium cell design adapts to intermittent field work with irregular charging cycles. Store BDC58/BDC70 battery packs and other tiny survey maintenance peripherals in our high-visibility yellow nylon data collector case; reinforced canvas belt loop supports waist hanging for convenient cross-region field instrument repair transport.
