This OEM-spec BDC46B lithium battery pack solves mainstream Sokkia reflectorless total station power failure issues: aging internal lithium cells causing drastically shortened field runtime, cheap imitation batteries lacking multi-layer safety protection leading to bulging & overheating, corroded gold-plated contact shrapnel triggering intermittent power dropout, mismatched shell unable to lock tightly inside battery compartment, inferior cells with severe capacity attenuation after dozens of charge cycles, and non-OEM power packs inducing mainboard voltage fluctuation during long-time reflectorless measurement. Standard 7.2V 2600mAh high-density lithium cell group with built-in full safety protection PCB, perfectly match original SET/CX/NET series instrument power circuit, deliver stable all-day continuous power supply for rural large-area cadastral mapping, municipal highway control network layout, open-pit mine high-precision topographic survey and tunnel long-term deformation monitoring projects.

Product Overview

The Sokkia BDC46B dedicated Li-ion battery pack is an integrated rechargeable power module exclusively developed for Sokkia mid-range reflectorless total stations and SDL30 digital level, fully interchangeable with BDC46A / BDC46C same-series battery models. Complete integrated layered structure: high-stability 2600mAh lithium-ion cell core, built-in auto-reset overcharge / over-discharge / overcurrent / short-circuit / over-temperature five-fold safety protection PCB, dual large-area thick gold-plated elastic conductive contact shrapnel, matte black impact-resistant ABS outer casing, integrated molded anti-loose positioning lock buckle matching instrument battery compartment. Internal lithium cells adopt low self-discharge technology, effectively reduce capacity loss during long-term idle off-season storage, no memory effect compared to Ni-MH batteries. Double-sided gold-plated contact terminals resist oxidation, mud and underground tunnel damp corrosion, maintain stable constant high-current output under harsh rainy, muddy construction environments without sudden instrument shutdown during reflectorless long-distance ranging. Hard black ABS shell with full UV anti-aging coating, anti-drop and anti-brittle at -20℃ low-temperature plateau field work, no permanent deformation after backpack extrusion and rock collision. Independent multi-functional safety protection circuit automatically cuts off power input/output during abnormal charging and discharge, effectively protect expensive total station mainboard, laser ranging module and angle measuring encoder from burnout damage. Direct plug-and-play installation without wiring modification, only compatible with CDC68 single/dual slot dedicated lithium battery chargers for safe standard charging.

Core Advantages & Practical Structural Design

• 100% OEM shell dimension, contact terminal spacing, lock buckle structure and 7.2V lithium cell voltage parameter fully consistent with factory original BDC46B battery, direct drop-in replacement for aging, bulging, short-runtime original battery packs
• Standard 2600mAh high-capacity lithium cell group, zero memory effect, stable continuous power supply, greatly extend single-day field working time compared to low-capacity imitation battery packs, support over 12 hours continuous reflectorless measurement
• Built-in five-fold auto-reset safety protection PCB, comprehensive protection against overcharge, over-discharge, overcurrent, short-circuit and overheating, eliminate mainboard burnout risk caused by field misoperation and terminal short-circuit
• Dual large-area thick gold-plated elastic conductive contact shrapnel, anti-rust anti-oxidation, solve intermittent power failure faults induced by mud, dust and slurry adhesion on contact surfaces during mine/tunnel construction
• Integrated molded positioning lock buckle design, firmly clamp battery inside instrument compartment without shaking, avoid power interruption during bumpy mountain transport and continuous automatic measurement vibration
• Matte black UV stabilized ABS shell, anti-scratch and anti-fading, easy to wipe surface mud and dust without leaving permanent marks during daily instrument maintenance; wide operating temperature range -20℃~+60℃ adapt all-weather construction
• Universal cross-model compatibility: fully fit Sokkia SET reflectorless series, NET network total stations, CX-50 engineering total stations and SDL30 digital level, only support CDC68 single/dual slot dedicated lithium chargers, coordinate with A00456 GPS-PDL composite cable and full PDL radio accessory set{insert\_element\_0\_}
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Compact rectangular integrated battery pack, lightweight only 105g, easy classified storage in instrument maintenance tool pouch alongside CDC68 chargers, iM52/iM55 silicone keyboard mats and survey optical mechanical spare parts

Sokkia SET/CX/NET Series Total Station Field Power Maintenance & Survey Application Scenarios

Necessary original power maintenance spare part for rural large-area cadastral boundary mapping, residential building construction layout stakeout, municipal pipeline control network measurement, small open-pit mine high-precision topographic survey and long-term foundation settlement monitoring Sokkia reflectorless total station & SDL30 level projects. When original BDC46B lithium battery ages with obvious runtime drop, shell bulging or poor-contact sudden power failure, survey maintenance technicians directly replace with this full OEM BDC46B battery pack to restore stable all-day uninterrupted power supply, prevent frequent instrument shutdown interrupting long-distance reflectorless angle & distance measurement data recording. Built-in five-layer safety protection circuit effectively reduce battery scrap rate and field power failure risk; low self-discharge lithium cell design adapts to intermittent field work with irregular charging cycles. Store this BDC46B battery pack 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.
