Ultra Low Maintenance Batteries

Saft ULM® (Ultra Low Maintenance) aviation batteries have a well-established track record with major aircraft manufacturers. The most advanced Ni-Cd technology, first developed by Saft, is used in its ULM aircraft batteries. These batteries have the industry’s lowest TCO due to their reduced maintenance and extended life duration. Since ULM batteries serve a flight-critical function, they meet more than 100 different qualification criteria to uphold safety.

ULM performance hinges on our plastic bonded electrode (PBE) technology. This engineering solution measurably reduces water consumption due to a reduction in overcharge current compared to sintered technology. Thanks to PBE technology, our ULM aircraft batteries provide added safety and longer life, even at high operating temperatures.
