My original PC680 lasted about 2 years of storage/building and 2 years of flying.
Its failure mode was to be able to charge very quickly up to full voltage but it had very little capacity. It would almost instantly drop down to low voltage with only a light load applied.
I replaced that battery in Oct. of 2012 and the replacement battery has fully failed today with the same symptoms. Last week it started acting like it was going to die and today it gave up the ghost. (with 3 of those months being panel upgrades and tests)
It has the same issue. It will almost instantly charge up to full voltage but it does not have any capacity to do any real work.
I took it to Advance Auto and they tested it with their tester and they said it only had 35% of its rating in capacity left.
I have always used the Odyssey Ultimizer 6amp charger. I keep it attached nearly all the time the plane is in the hangar. My aircraft electrical system runs at 14.3 to 14.4 volts in flight.
So what killed these batteries that are suppose to have a long life cycle?
