Upgrading to the Concorde lead acid battery reduces cost per flight hour as the result of a lower cost of acquisition, reduced maintenance requirements and Hazmat exempt shipping. Concorde’s RG-292-102 and RG-292-103A do not require watering and pose no risk of thermal runaway.

The advanced lead acid technology of a Concorde battery is exhibited by instant spooling of the engines upon starting. Helicopter operators depend on Concorde batteries for reliability in remote locations and extreme weather conditions with Concorde certified performance at temperatures ranging from -40°C to 71°C.
