TB44 True Blue Lithium-Ion Battery

The TB44 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 turbine market, including fixed-wing and rotorcraft applications, the TB44 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 40% lighter than lead-acid or nickel-cadmium alternatives.

The 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 ARINC 429 communication to the cockpit.
