ULM® (Ultra Low-Maintenance) Ni-Cd batteries

Saft has developed the most advanced Ni-Cd technology for our ultra low-maintenance ULM® batteries for the aviation industry. With reduced maintenance needs and extended life, ULM® batteries deliver the industry’s lowest total cost of ownership (TOC) and meet more than 100 different qualification criteria. 

ULM® batteries need to be maintained less than half as frequently as traditional batteries thanks to their plastic bonded electrodes. They are highly reliable and when maintained properly can have a life of up to 10 years thanks to their high-quality proprietary separator systems.
