At this chemical processing plant, two new switchgear systems were added to support new operations. Two new 120vdc Enersys Varta NiCd battery strings were designed and installed to back up these switchgear. The project included Enviroguard Hawk Spill Containment systems, racks, Hindle AT-10 chargers and 92 NiCd cells in each string. An Alber MPM-100 battery monitoring systems was added as well to each string. Battery was also discharged to confirm its capacity from the factory. An Alber DC resistive load bank was used in concert with a BCT-2000 to record the battery performance.

Two strings (2x176x2) of C&D XT4LC11s were replaced with Enersys DataSafe 4DXC-9B-FR UPS batteries on the existing C&D racks. The new battery proposed needed to provide 400kW for 10 minutes. The client also required that the new batteries have wrapped plates to prolong the battery life. Flame retardant jars and a 1.250 specific gravity were also specified.
Their Alber BDS-256 battery monitoring system was also removed, re-installed and re-programed/calibrated after the new cells were installed. The customer considered a VRLA, but after seeing the annual cost of it over a 3-4 year lifespan, they chose to stick with the 12 year Vented Lead Acid battery.
After this battery room was complete, they chose API to replace their batteries in a 2nd battery room the following year. The scope of work in this battery room was essentially identical to the first room.
This long time client has tasked API with several preventative maintenance services. From UPS to battery maintenance, they trust API to take care of their backup power systems to ensure zero downtime. In 2010, several batteries were replaced, including a UPS string. Enersys Genesis XE95 Pure Lead cells (red and black cells shown above) were used on one of three UPS strings. The client also has a Telecom room which we test and maintain.
This datacenter contracted API to conduct its comprehensive UPS battery maintenance and battery replacement program. As their VRLA battery systems are replaced, am acceptance load test is conducted after the installation to properly commission the new battery string. A regimented quarterly IEEE-1188 battery maintenance inspection is conducted on every string to ensure this datacenter’s operations and uptime are never compromised. They are proud users of Enersys DataSafe HX VRLA and DataSafe DX batteries.
This is a training facility which needs to ensure 100% uptime, 24/7. Each year, the oldest of the three battery strings is replaced. In addition, an annual UPS preventative maintenance procedure is performed with an IEEE-1188 battery inspection. This client has used both Enersys DataSafe HX and Exide GNB Sprinter VRLA batteries.
This critical datacenter site consists of seven VLA battery strings and API conducts quarterly IEEE-450 battery preventative maintenance. Every quarter both voltage and internal resistance levels are reported on every individual cell. On an annual level, specific gravity is also taken.
This facility has several types of stationary battery applications. API provides UPS (annual) and battery (quarterly) preventative maintenance services for this critical facility. The facility has a wide array of battery types including VLA flooded (UPS), flooded Nicad (switchgear) and sealed UPS VRLA batteries (UPS).
The battery system for the emergency lighting inverter was replaced in 2010 with Enersys Datasafe HX batteries. An acceptance test was conducted after installation to verify the battery’s capacity prior to placing it into service.
