Based on this test, it was decided to omit any further capacity checks and leave the batteries in the aircraft with no maintenance until failure. Executive Jet Aviation Inc. In the Citations, there were no significant problems reported with the nickel-cadmium batteries. Capacity checks were not made and essentially no maintenance was performed on the batteries while in service. Conclusions Valve regulated lead-acid batteries provide electrical performance that is comparable with nickel cadmium batteries. VRLA can deliver excellent high rate performance at low temperatures.
VRLA batteries offer the user a maintenance free aircraft battery.
