“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 costs

  • 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.”
