Here are the readings that I get. Battery Voltage this morning is 12.3.

A question. Is a fully charged 12V lead-acid battery held at 14V a voltage stabiliser? People seem to think so but I doubt it. If you disconnect the battery while the alternator consistently puts out over 13V will there be much difference in AC components on the bus? Is there an AC on top of DC internal impedance measurement out there somewhere that I can't find a reference to? I hope somebody knows more. Thank you.

If your generator goes into an overvoltage charge situation it won't take long to boil the battery. Once that happens the buss will go overvoltage too, Noel -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Jan de Jong Sent: January 2, 2011 1:53 PM Subject: AeroElectric-List: is battery filter or dead weight?
