For charging the valve-regulated lead-acid battery, a well-matched charger should be used because the capacity or life of the battery is influenced by ambient temperature, charge voltage and other parameters. Cycle use is to use the battery by repeated charging and discharging in turn.
This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.
It provides instructions for proper storage, servicing, replacement, repair, and disposal of RG® Series valve regulated lead-acid main aircraft batteries manufactured by Concorde Battery Corporation. Batteries covered by this CMM are designed for engine starting applications and may also be used as an emergency power supply.
REMOVING THE PRESSURE RELIEF VALVE VOIDS THE WARRANTY. When valve regulated batteries are on charge, oxygen combines chemically with the lead at the negative plates in the presence of sulfuric acid to form lead sulfate and water. This oxygen recombination suppresses the generation of hydrogen at the negative plates.
In this revision, particular reference is made to ‘General Definitions’, ‘Product Characteristics’, ‘Design Life’, ‘Service Life’ and ‘Safety’. A valve regulated cell or battery is closed under normal conditions by a non-return control valve that allows gas to escape if the internal pressure exceeds a predetermined value.
Nickel-cadmium and lead-acid battery safety concerns include the possibility of fire and venting violently. For batteries not covered by TSO-C173/C173A, there are no airworthiness limitations associated with the installation of a Concorde valve-regulated lead-acid battery in an aircraft.
