Preventative Maintenance

Wholesale Batteries offers preventative maintenance programs tailored for Vented Lead-Acid (VLA)/Flooded Wet Cells, Valve-Regulated-Lead-Acid (VRLA), Gel Batteries, and Nickel-Cadmium (NiCad/Ni-Cd) batteries.

The “heartbeat” of many systems today is our batteries. Batteries support critical components during an outage of utility power. Uninterruptible Power Supplies (UPS), Telecommunications, Switchgear, Generators, Emergency Lighting, among others continually rely on batteries to provide continued protection. Wholesale Batteries has over 40-years’ experience servicing batteries supporting an array of critical power components.

Our preventative maintenance programs provide essential analysis to resolve deficiencies before they potentially compromise a system resulting in an outage. Identify conditions before they lead to battery failure. Our team regularly identifies common issues allowing clients to have confidence in their batteries. Some of the leading issues found during initial inspections are: inadequate air exchange, ambient temperature of battery rooms not being maintained, excessive cycling, improper sized batteries, improper charging,

All procedures and inspections are governed by IEEE, manufacturer specifications, NERC, and the clients’ expectations. Our battery maintenance programs are tailored to meet your requirements – inspections can occur monthly, quarterly, or annually to meet your expectations. Scheduling is coordinated during normal hours or after-hours depending on what is best for your organization.

IEEE Standard:

  • IEEE 450 –Maintenance, Testing, and Replacement of Vented Lead Acid (VLA) Batteries
  • IEEE 1188 – Maintenance, Testing, and Replacement of Valve-Regulated-Lead-Acid (VRLA) Batteries
  • IEEE 1106 – Maintenance, Testing, and Replacement of Vented Nickel-Cadmium Batteries

Features of our battery preventative maintenance program includes:

  • Complete visual inspections: uncovering signs of battery defects or degradation, leaks, corrosion, etc.
  • Cleaning the tops of batteries, racking, cabinets, etc.
  • Measurements: measure & record float voltages, internal jar resistance, connection resistance, battery & ambient temperatures, charger/rectifier parameters, specific gravities (if applicable).
  • Re-torque of all battery connections
  • Watering of flooded cells (if applicable)
  • Battery Capacity testing
  • Corrective maintenance if conditions are met requiring immediate action during time of service.
  • Comprehensive report with services performed during the visit, results of the measurements, and recommended corrective actions, if any.

Wholesale Batteries works with all battery manufacturers, handling warranty issues, corrective deficiencies, single jar replacements, full string replacements. Some of the leading manufacturers we service are: C&D, Enersys, Exide, GNB, East Penn Deka, NorthStar, Fiamm, CSB, Vision, Leoch, Hoppecke, Saft, Alcad, Narada, Power Sonic, and others.
