Micro Maintenance Batteries

Marathon's Micro Maintenance () batteries are improved nickel cadmium batteries that supply reliable power for large commercial aircraft, regional aircraft, military aircraft, corporate aircraft and helicopters. batteries are offered in sizes from 17 to 75 ampere-hours, and in most cases, they're interchangeable with existing batteries. Therefore, you can easily make the change without aircraft modications and can support the product with your existing battery shop equipment. They're also FAA-PMA approved for many aircraft models.

The battery utilizes the latest Polymer Bonded Electrode (PBE) negative electrode technology to ensure optimized performance and dependability. Today's PBE technology was pioneered by MarathonNorco decades ago. Now, we've refined this unique technology to give you greatly reduced maintenance costs. Compared with standard nickel cadmium batteries, this technology provides reduced water consumption, faster recharge and greater energy density, which translates into longer flight hours between servicing, increased capacity retention, and faster, cooler engine starts.

SuperPower Batteries

MarathonNorco Aerospace pioneered the development of sintered plates. The company was the first to use Bunsen vent valves on nickel-cadmium cells, and the first to manufacture hermetically-sealed nickel-cadmium cells.

Sintered plates feature improved woven-wire substrate. They're stronger, blemish-free, and offer lower resistance. Exclusive high heat-resistant polypropylene separator material provides longer life and better high-rate performance at extreme temperatures. Heavy-gauge connectors, large terminals and heavy-duty screws give superior conductivity.

The rechargeable vented-cadmium batteries are widely used for engine starting and emergency power in commercial, corporate and military aircraft - fixed wing and rotary. They also supply power for military weapons, ground vehicles, medical and telecommunications equipment.

The rechargeable sealed-cadmium batteries supply reliable power for everything from emergency lighting in commercial airliners, military communications, military aircraft flight control systems to backup power on F-16 Fighter jets.
