Concorde Battery (Stand 2404) is exhibiting its range of improved lead-acid aircraft batteries. Although lead-acid is old battery technology, having been invented in 1859, it may be soon the only one available for aviation use. According to Concorde executives, nickel-cadmium batteries could be banned to protect worker health and lithium-ion models seem too hazardous for airborne applications.
The FAA has issued Special Conditions for the Cessna 680 Sovereign, for which Cessna proposes to use rechargeable lithium-ion main batteries and APU start batteries. According to the FAA, lithium-ion batteries differ significantly from the nickel-cadmium (Ni-Cad) and lead-acid rechargeable batteries currently approved.
Gulfstream Aerospace selected Securaplane’s lithium-ion battery as standard equipment on its new G650. The multimillion-dollar deal marks the first time a Gulfstream aircraft will feature the technology, which is some 50-percent lighter than conventional NiCad or lead-acid batteries and carries a higher energy density. The subsidiary of UK-based Meggitt said the weight reduction per shipset equates to nearly one passenger.
Gulfstream Aerospace has chosen Securaplane’s lithium-ion battery as standard equipment on its new G650 business jet. The multi-million-dollar deal marks the first time a Gulfstream aircraft will feature the technology, proven some 50-percent lighter than conventional NiCad or lead-acid batteries and carrying a higher energy density.
Bombardier Challenger 300 operators now have a choice of replacing the jet’s original nickel-cadmium main ship battery with a new Concorde RG-441 lead-acid battery. The FAA has awarded Concorde (Booth No. 2039) a supplemental type certificate (STC No. ST01488WI) for installation of the RG-441 lead-acid battery.
CRS Jet Spares is offering a new low-current/constant-voltage battery trickle charger that can be used to float-charge nicad and lead-acid mainship batteries. According to Armando Leighton Jr., the company’s CEO, the unit is a low-cost way to maintain the charge of batteries in storage or on aircraft so that fully charged batteries are available when needed.
Saft has been selected to supply batteries for both China’s AVIC ARJ21 regional jet and its Russian competitor, the Sukhoi Superjet. The company is already set to provide the Lockheed Martin F-35 Lightning II with batteries for the low-rate initial production phase.
Lithium batteries, as used in cellphones, laptops and other electronic equipment, have been in the news recently, as airlines have severely limited their carriage on aircraft due to the hazard of fire. So it might not seem an opportune time to begin marketing a lithium battery designed to replace nicad and lead-acid aircraft batteries.
Aircraft maintenance does not exactly move forward technologically at the speed of light. Instead, it appears the industry is in a constant state of making things incrementally better. A small innovation here, some modification to an existing procedure there, a reemphasis on the importance of service, and the result is that operators get better, faster, more cost-effective maintenance.
Securaplane recently announced that CRS Jet Spares, a Securaplane mainship and emergency battery line distributor, has sold its 20,000th mainship battery. Securaplane emergency battery systems use Hawker sealed lead acid batteries instead of nicads and are either original or approved replacement equipment for most business jets.
