TB17

Advanced Lithium-ion Battery

TB17

Ideal for the piston and turbine market, the TB17 Advanced Lithium-ion Battery starts the aircraft’s engine quickly and features superior energy density — Nanophosphate® lithium-ion cells offer 3x the energy per kilogram, resulting in a battery that is 45% lighter than lead-acid or nickel-cadmium alternatives.

Features

  • Communicates battery status to the cockpit
  • Higher voltage during engine start — Less wear, less maintenance and increased useful life
  • 2-year maintenance interval — 50 – 75% less scheduled maintenance cost
  • 6 years useful life
  • Designed and built in Wichita, Kansas, USA
  • 2-year limited warranty
  • 17 amp-hour battery nominal at 23°C/73.4°F
  • Weighs 15.6 lbs. — 45% lighter than lead-acid or nickel-cadmium alternatives
  • Advanced Nanophosphate® lithium-ion cell chemistry from A123 Systems, LLC — 3x the energy per kilogram when compared to lead-acid and nickel-cadmium cells
  • 7 engine starts in 7 minutes
  • 30 minutes (at 34 amps) for complete recharge when the battery is fully discharged
  • Superior performance at higher temperatures (up to 50°C/122°F)
  • Overcharge, over-discharge, over-current, short circuit, over-temperature, under-temperature and charge current limiting protection
