Battery Installation | Hurlburt AFB, FL

At this United States Air Force Base, API was contracted to remove and replace all the VRLA batteries from this 480-volt battery string.  40 batteries were removed from the cabinet and replaced with Enersys DataSafe 12-HX400 batteries.  After all the batteries were torqued to manufacturer’s specifications, a proper IEEE-1188 (voltage and internal resistance values) was conducted and then the battery string was placed back online with
the UPS.  The old batteries were palletized and taken to a certified recycling facility and properly disposed of.

Battery Installation | Lawrence, KS

This client needed to replace their 25 year old C&D wet cell battery systems in two locations.  They were both 48vdc telecom systems.  Existing Lorain chargers were reconnected after the battery replacement was complete.  EnerSys PowerSafe DDm batteries were used to replace the old C&D wet cells.  Thorough IEEE-1188 inspections were done with an Alber Cellcorder CRT-400 and acceptance capacity (load) testing was completed as well with an Alber DC Load bank and BCT-2000.

UPS | Bloomington, IL

In 2005, API installed and commissioned the client’s Alber BDS-256 battery monitoring system on 14 battery strings.  Every year, API conducts capacity (load) testing and thermal infrared scanning services on all critical battery systems. For each capacity test, the battery’s discharge and performance data is captured with the BDS-256 and a comprehensive report is provided.  API also performs quarterly preventative maintenance on the client’s Alber BDS-256 battery monitoring systems to ensure proper operation and that it is calibrated to factory specifications.

UPS | Nashville, TN

At this datacenter facility, API removed and recycled two strings (80 total jars) of VRLA batteries and then installed new Enersys DataSafe 12HX-400 batteries for the client’s UPS. Four spare batteries were also removed and installed. After the battery replacement and proper charging, an IEEE-1188 inspection was conducted prior to commissioning the battery strings with an acceptance test. During the acceptance testing, an Alber Battery Capacity Test Set (BCT) and Alber DC Resistive Load bank were used to discharge and capture the battery performance data. API also conducts annual preventative maintenance on this datacenter’s Alber Battery Monitoring Systems.

Telecom | Kansas City, MO

This public power utility company chose API to provide a turnkey installation to remove their depleted 48v telecom battery system, and replace with an Enersys G Series battery with an Alber battery monitoring system. The old battery was properly removed and recycled.

Telecom | Kansas City

API was responsible for providing a new rack, as well as the replacement battery cells.  All batteries were replaced — two parallel strings with four 6-cell modules per string, supplying a nominal 48VDC. (2x4x12).  Battery installed was EnerSys model 12HX-400.  All posts, intercell connectors and terminal lugs were prepared and cleaned using a light coating of “No-Ox” to prevent corrosion.  Using an insulated torque wrench, all connections were verified per the manufacturer’s recommendations.  After installation, voltage values were verified and the rectifier and telephone system were restarted.

UPS | Kansas City, MO

This downtown Kansas City datacenter had two strings of C&D Libert batteries (80 jars total) that required replacement in order to support their UPS load.  API was contracted to remove and replace these 80 batteries. EnerSys Datasafe 12HX-400 valve-regulated lead acid batteries (VRLA) were used as the replacement cells.

After the battery replacement was complete, an Alber BDS-40 battery monitoring system was installed and commissioned.

Switchgear | Kansas City, MO

This private power utility hired API to provide a turnkey solution to retrofit their legacy backup power systems.  A new battery building was purchased and outfitted for each of the three substations.  After the first substation was complete, the other two followed suit.

The substations were equipped with new batteries (Enersys PowerSafe EC), racks, Enviroguard spill containment and Hindle AT10 chargers.

New distribution feeds were required to be ran from the existing generator cabs as well.  After installation, the batteries were acceptance (load) tested and the power loads were transferred to the new system. Later, the old batteries were de-commissioned and properly recycled.

UPS | Kansas City, MO

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.

UPS & Telecom | Kansas City, KS

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.
