I had checked the voltage at rest and everything seemed reasonable but in flight there were electrical failures and problems. The A&P put the batteries on a load test and they failed immediately. New batteries=no more problems. So, a good annual check is load testing the batteries just to make sure they can handle the loads from hyd pumps and other high- amperage draws.
