Pilatus PC-12 STC With True Blue Power® Lithium-ion Main Ship Battery, More Power Less Weight

Finnoff Aviation Products now offering lithium-ion main ship battery upgrade

Pilatus PC-12

WICHITA, Kan. — True Blue Power announced Finnoff Aviation Products has selected the company’s TB44 (46 amp-hour) main ship battery for a lithium-ion battery Supplemental Type Certification (STC) kit, available on Pilatus PC-12, PC-12/45 and PC-12/47 single-battery aircraft. An amendment to include dual-battery aircraft is currently in progress.

“We are especially impressed with the significant weight savings of 32 pounds over the lead acid battery, as well as the high and low temperature advantages—without having to remove the battery in cold-soak conditions,” said Pat Finnoff, Vice President of Marketing for Finnoff Aviation Products. “This especially speaks to the PC-12, which is so suitable for these adverse weather situations.”

True Blue Power’s TSO-certified TB44 lithium-ion aircraft battery utilizes the most sophisticated NanoPhosphate® lithium-ion chemistry available to deliver unmatched power, safety, life, weight savings and energy. In addition to superior performance, the engine start battery offers PC-12 owners a long list of operational benefits:

Faster, cooler engine starts

  • Longer life for power plant components
  • Reduced risk of “hot start”
  • Significantly lower Interstage Turbine Temperature (ITT)

Rapid recharge

  • 15 minutes for complete recharge when the battery is fully discharged on a typical aircraft

Significantly reduced maintenance and operational

  • 8-year (average) useful battery life
  • 2-year maintenance intervals
  • Reduced replacement intervals

Increased aircraft appreciation value

Superior high temperature and cold weather performance

  • -40°C to +70°C (-40°F to +158°F)
  • Battery removal not required in cold-soak conditions

Increased dispatch reliability

“The TB44 is a significant performance upgrade for PC-12 operators currently utilizing heavier, more maintenance-intensive batteries on these aircraft,” said Erik Ritzman, Director of True Blue Power. “The TB44 aircraft battery is reliable, safe, low-maintenance and ideal for operation in even the most challenging environments.”
