Case Study: Southwest Saves Big with NexSys
Southwest Airlines saves big with NexSys PURE battery-powered baggage tractors
ENERSYS DECEMBER 2020
In 2015, Southwest Airlines® began powering 70 new electric baggage tractors with NexSys® PURE Thin Plate Pure Lead (TPPL) batteries at Chicago’s Midway International Airport. The carrier had just started using them in its baggage tractors station-wide, after a multi-city trial proved that the TPPL batteries would eliminate the watering maintenance and acid spills associated with flooded lead acid batteries.
Southwest was getting up to four years of service out of the gel batteries, but that involved sending them out frequently for repairs. Attempting such services in-house was impractical and would have required additional training, but sending the batteries out took tractors out of service, slowed operations, and added to overall battery power costs. NexSys PURE batteries promised a much better solution.
