The new Saft battery system is designed to offer 777 operators superior performance and lower total cost of ownership (TCO) by extending maintenance intervals. Customers can retrofit existing 777 airplanes with these new systems distributed by Boeing subsidiary Aviall.
The Boeing 777 battery system provides onboard power for APU (auxiliary power unit) starting and backup for critical systems. It comprises a 60 Ah, 24 V ULM battery together with a charger. Two battery systems are fitted to each airplane.
The 777 contract is Saft’s first direct contract with Boeing as a Tier 1 supplier. Saft has been providing batteries to Boeing indirectly for more than 30 years working via integrators. Boeing recently recognized Saft as “Supplier of the Year” in the Advantage category. Saft also has a long-standing relationship with Aviall to offer extensive product and related service support for the worldwide commercial aircraft fleet.
Saft ULM aviation batteries have a well-established track record with major aircraft and helicopter manufacturers. They offer the ideal combination of high performance, low weight, long service life and ultra-low maintenance requirements that enable significant reductions in the TCO for commercial aircraft.
The ULM design also benefits from easily replaceable spare parts as well as the capability to be stored for long periods – up to 10 years – with no deterioration in performance. The 777 ULM batteries are manufactured in Valdosta, Georgia, in the United States.
