Gary asks:
<<
What voltage is your regulator set for charging? The Panasonic specs list
2 voltages - one for trickle (like in a UPS) and one for deep cycle (like a
golf cart). There isn't a spec for aircraft (auto) type usage.
>>
The trickle voltage is intended to hold the charge in the battery and prevent self discharge. The cycle voltage is for charging a battery that has lost a significant amount of its charge. I use the low end of the cycle voltage or 14.5 VDC and 29.0 VDC for 14 and 28 volt systems respectively. Remember that the alternator is a 3 phase AC generator that has an internal full wave bridge rectifier (6 diodes) so its output is rectified AC (DC with a lot of ripple). Be sure to measure your charge voltage at the battery terminals so you read what the battery is seeing and not what the alternator is producing.
