Job Applications

• Excavation and Grading Operations: Essential for maintaining charged receivers during extended earthmoving projects where equipment downtime directly impacts productivity. Having a backup charger on-site ensures continuous operation even when primary chargers fail or are misplaced during equipment moves between cut and fill areas.
• Multi-Crew Construction Sites: Enables fleet managers to maintain multiple LR Series receivers across different work zones without sharing chargers between crews. This reduces equipment conflicts and ensures each operator has the power supply needed to complete grade-checking tasks without delays.
• Pipeline and Utility Trenching: Critical for linear projects where crews work along extended corridors and may need charging capabilities at multiple staging areas. The standard wall plug design allows easy setup wherever temporary power is available, from site trailers to equipment storage containers.
• Agricultural Land Leveling: Supports farmers and land improvement contractors who run long operational days during planting and harvesting windows. A replacement charger ensures receivers stay ready through seasonal peak periods when equipment rental or replacement isn't practical.
• Road Construction and Paving: Provides highway contractors with charging redundancy for grade control systems that guide asphalt placement and subgrade preparation. The factory-original specifications ensure consistent charging performance that won't damage sensitive receiver electronics in high-value laser systems.
• Site Development and Mass Grading: Supports large-scale residential and commercial development projects where multiple machines equipped with LR receivers operate simultaneously. Having dedicated chargers for each receiver eliminates charging bottlenecks and keeps automated grade control systems operational throughout extended site preparation phases.

This makes it an excellent choice for contractors working on international projects or equipment rental companies serving diverse markets.

How long does it take to fully charge an LR Series receiver?

Charging time typically ranges from 3 to 5 hours depending on the specific LR receiver model and the battery's current discharge level. The factory-original design ensures optimal charging rates that maximize battery life while providing the fastest safe charging speed. For best results, charge receivers overnight or during lunch breaks to ensure full power for afternoon operations.

Why should I choose a factory-original charger instead of a third-party alternative?

Factory-original Spectra chargers like the 991604-99 are engineered specifically for LR Series receivers, delivering precise voltage and current specifications that protect sensitive electronic components. Third-party chargers may save a few dollars initially but risk damaging expensive receivers, voiding warranties, or providing inconsistent charging performance.
