Bottom line is that it is the same battery it always was, they just reduced its rating after they actually tested it. The prior rating was an estimate.[/quote]
Thanks Brian. |

Do you recall why he said this is a bad idea? It would seem that Odyssey makes these quick connectors to be used in just that manner. I will admit I have never read through the Odyssey battery literature to see what they say regarding this issue and there is no doubt Bill Bainbridge is much more knowledgeable than I. |
Good connections...

Thanks for bringing this up and I stand corrected. I contacted PP and they confirmed they did indeed tap off the field terminal for the internal regulator sense functlion. However the problem I see with regulating the alternator by increasing the resistance of the field wire (same as installing a resistor in the field supply) is that as the voltage drops on the bus and the field draws more current there will be an additional voltage drop at the field, so the alterator will overcompensate. So the higher the field current the higher the bus voltage will be. At least thats my theory, I would be very interested to know how it actually works though in the real world. |
It died on the 4th
I installed a new Concorde battery and flew with a good volt meter, I'm only charging at 13.90 volts. could this be cutting the battery life short? I am/was using the Odyssey charger between flights.

Russ,
The normal charging voltage for a lead acid battery is 13.8 -14.2 volts. This is where most regulators are set. If it is not a sealed battery and you charge it with too high of a voltage, you will overheat it during the charge cycle and boil the water out which will require you to frequently check the level of the battery. I don't believe that charging it with the 13.9 volts you are seeing, will damage or shorten the life of your battery. What I question is the need to continually trickle charge your battery. Rarely do I see aircraft trickle charged during inactivity. The only instance you may need to do this is if the aircraft is rarely flown. I would contact Concorde and see what they recommend for both the charging voltage and the maintenance voltage. |

If you have an emergency bus with a diode in the circuit, voltage will vary depending on where you take the reading. The diode will absorb about 0.5v and make your system appear to be undercharging if you read voltage downstream from the diode. But you need ~14.5v going to the battery. |
What Sam said. Odyssey recommends charging there batteries at at least 14.5V.

So I just put this battery in http://www.concordebattery.com/flyer.php?id=36 what?s the recommended charging voltage for it? I believe I can adjust my B&C regulator, I?ll be calling Bill (B&C) Monday. |
