Battery Watering Valves

RBS Single-Point Watering System for Locomotive Batteries

These are the ONLY watering systems designed specifically to work on ALL MAJOR brands of starting batteries, and to survive the extreme temperatures and vibrations on locomotives. Frequent locomotive starts demand aggressive charging which results in increased water use within the batteries. Maintaining the proper level of water in each cell is essential to ensure cranking amps are available.

Easier & Superior Maintenance

  • Ensures all cells are watered – including those in the very back of compartment
  • Maintainer can complete watering tasks in about one or two minutes
  • Will automatically ensure the correct amount of water is delivered to each cell, every time
  • Typical install requires only about 15 minutes
  • Standard hose and coupler connections available

Designed for Operational Safety

  • Designed to allow for electrolyte expansion to help eliminate dangerous acid spills
  • The ONLY single-point watering system that provides internal flame arrestors
  • Eliminates the need to lift or remove a battery from the compartment before watering
  • De-gas chamber allows normal release of gasses

RBS Battery Nurse

RBS BatteryNurse™ Systems

RBS BatteryNurse™ systems provide high-performance testing and charging for optimal battery health and reliability. Systems are designed to maximize process flow within each facility so that locomotive batteries can move expediently through the stages: Triage > Watering > Bulk Charge >Test > Float Charge. This creates a store of qualified batteries that are available for immediate service. The BatteryNurse™ system prevents installation of bad batteries or improperly charged batteries that could cause no-starts and require redundant maintenance.

RBS specializes in the highest caliber products and services to help railroads obtain optimum performance and viability from their locomotive starting batteries.

Canadus Locomotive Battery Desulfator

Safe, proven and patented High-Frequency Battery Energizing (HFBE) technology that combats battery failure by eliminating sulfation problems, the primary reason for battery deterioration. Easy to install and use; no special tools are required. When batteries are charging, Canadus battery energizers draw energy from the charger (DC side) and automatically work to keep the battery plates clean.

  • 32V & 64V
  • Reverse polarity protected
  • Operating Temperature: -45°…+85°C
  • Green LED indicator
  • M10 (3/8″) ring terminals
