The TB17 Advanced Lithium-ion Battery uses the most sophisticated lithium-ion chemistry available, providing aviators with an unmatched advantage
of power, safety, life and energy.
Ideal for the piston, turbine, and emergency power market, the TB17 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.
This advanced battery system is engineered to deliver an overall lower cost of ownership with a 2-year maintenance schedule, efficient engine starts, extended useful life and intelligent battery status communication to the cockpit.
17 amp-hour battery nominal at 23°C/73.4°F
Weighs 16 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
