Preventative Maintenance Services
There are many factors that affect battery efficiency such as heat, age and battery chemistry. A preventative maintenance program will help lengthen the life of a battery system. Below is highlights of a typical preventative maintenance program. All maintenance activities conform to NERC PRC-005 standards.
Vented Lead Acid Batteries
Every 4 calendar months
- Verify station DC voltage
- Inspect electrolyte level
- Inspect for unintentional grounds
Every 18 calendar months
- Verify float voltage of battery charger
- Verify battery continuity
- Verify battery terminal connection resistance
- Verify battery intercell or unit to unit connection resistance
- Inspect cell condition of all individual battery cells (where visible)
- Inspect physical condition of rack
Valve Regulated Lead Acid Batteries
Every 4 calendar months
- Verify station DC voltage
- Inspect for unintentional grounds
Every 6 calendar months
- Measure battery/cell internal ohmic values
Every 18 calendar months
- Verify float voltage of battery charger
- Verify battery continuity
- Verify battery terminal connection resistance
- Verify battery intercell or unit to unit connection resistance
- Inspect physical condition of rack
Nickel Cadmium Batteries
Every 4 calendar months
- Verify station DC voltage
- Inspect electrolyte level
- Inspect for unintentional grounds
Every 18 calendar months
- Verify float voltage of battery charger
- Verify battery continuity
- Verify battery terminal connection resistance
- Verify battery intercell or unit to unit connection resistance
- Inspect cell condition of all individual battery cells (where visible)
- Inspect physical condition of rack
Per NERC PRC-005 Standards – A capacity test on every battery system shall be completed at least every 6 years.
