Price: $37.99 | Compatible Instruments: Sokkia SET5A / SET5E / SET5F / SET5FS / SET5S / SET5W / SET5WS Waterproof Series Total Station; Matching Dedicated Charger: CDC29 / CDC19 / CDC27; Matching Accessories: Sokkia A00456 GPS-PDL Cable, iM52/iM55 Silicone Keyboard, RTK Carbon Fiber Sharp Point

This OEM-spec BDC25B nickel-metal hydride battery pack solves common power supply defects of classic Sokkia SET5 waterproof total stations: aging internal cells causing drastically shortened field runtime, shell bulging induced by long-term overcharging, corroded gold-plated contact terminals triggering intermittent power cut-off, deformed casing unable to lock tightly inside instrument battery compartment, low-capacity imitation batteries failing to support all-day continuous stakeout & control network static observation, and mismatched third-party power packs leading to mainboard voltage instability. Standard 6.0V high-density Ni-MH cell group with built-in multi-layer safety protection PCB, perfectly match original SET5 series instrument power circuit, deliver stable long-duration power supply for rural cadastral boundary mapping, municipal highway layout, open-pit mine topographic survey and tunnel deformation monitoring projects.

Product Overview

The Sokkia BDC25B dedicated Ni-MH battery pack is an integrated rechargeable power module exclusively developed for Sokkia SET5 waterproof total station series, fully interchangeable with BDC25 / BDC25A legacy battery models. Complete integrated layered structure: high-capacity low self-discharge Ni-MH cell core, built-in auto-reset overcurrent / over-discharge / short-circuit protection PCB, dual large-area gold-plated conductive contact shrapnel, matte dark gray impact-resistant ABS outer casing, built-in positioning lock buckle matching instrument battery compartment. Internal Ni-MH cells adopt advanced low self-discharge technology, effectively reduce capacity attenuation during long-term idle storage and seasonal off-season placement. Double-sided gold-plated contact terminals resist oxidation, mud and tunnel damp corrosion, maintain stable constant current output under harsh rainy, muddy construction environments without sudden instrument shutdown. Hard ABS shell with UV anti-aging coating, anti-drop and anti-brittle at -10℃ low-temperature plateau field work, no permanent deformation after backpack extrusion and rock collision. Independent safety protection circuit automatically cuts off power output during short-circuit, reverse connection and over-discharge, effectively protect expensive total station mainboard from burnout damage. Direct plug-and-play installation without wiring modification, only compatible with CDC29 / CDC19 / CDC27 dedicated Ni-MH battery chargers for safe standard charging.

Core Advantages & Practical Structural Design

• 100% OEM shell dimension, contact terminal spacing, lock buckle structure and 6.0V cell voltage parameter fully consistent with factory original BDC25B battery, direct drop-in replacement for aging, bulging, short-runtime original battery packs
• High capacity Ni-MH cell group (2700mAh optional), stable continuous power supply, greatly extend single-day field working time compared to low-capacity 1400mAh imitation battery packs
• Built-in multi-functional auto-reset safety protection PCB, triple protection against overcurrent, over-discharge and short-circuit, eliminate mainboard burnout risk caused by field misoperation and terminal short-circuit
• Dual large-area thick gold-plated conductive contact shrapnel, anti-rust anti-oxidation, solve intermittent power failure faults induced by mud, dust and slurry adhesion on contact surfaces
• 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 dark gray UV stabilized ABS shell, anti-scratch and anti-fading, easy to wipe surface mud and dust without leaving permanent marks during daily instrument maintenance
• Exclusive cross-model compatibility: fully fit all Sokkia SET5 waterproof series total stations, only support CDC29 / CDC19 / CDC27 dedicated matching Ni-MH chargers, 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 pack, lightweight easy classified storage in instrument maintenance tool pouch alongside CDC29 chargers, silicone keyboard mats and survey mechanical spare parts

Sokkia SET5 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 SET5 total station projects. When original BDC25B battery ages with obvious runtime drop, shell bulging or poor-contact sudden power failure, survey maintenance technicians directly replace with this full OEM BDC25B Ni-MH battery pack to restore stable all-day uninterrupted power supply, prevent frequent instrument shutdown interrupting precision angle & distance measurement data recording. Built-in multi-layer safety protection circuit effectively reduce battery scrap rate and field power failure risk; low self-discharge cell design adapts to intermittent field work with irregular charging cycles. Store this BDC25B 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.
