Brand new 12V battery on a brand new TT. Even after several days hooked to 120V line voltage, and a few very brief draws of 12 while in storage, my battery voltage is 12.3...
With plans for 6V batteries
PD 4655L Wildcat is arriving tomorrow!
Ok there are basically three classes of converters. one is (Thankfully) becomming more and more rare
1: Feroresonant like the Magnetek 6300 Converter/Charger This is, by today's standard, JUNK and is the one which is more and more rare
This unit was usually a 30 amp Converter and a 3-4 amp CHARGER the problem is it had poor regulation. the Converter side was NOT filtered and when the battery was full up.. IT JUST KEPT CHARGING and boiled them dry swiftly.
2: Single stage. IE: Parallax 7300 Not a bad converter/power supply but not a good battery charger. May well NEVER get to full. 90% yes but never full Parallex bought out Magnatek and dumped the 6300 line.
Now the 7300T (Two stage on a timer) MIGHT fill em if you unplug and plug back in to reset the timer.
3: 3 or 4 stage converters like the Progressive Dynamics WIZARD jobs
And I might add I've been looking for a better charger for 14 years.. Still looking.. (nuff said)
These start with high current. then taper off to low current but about 14.5 volts, finally they drop to 13.6 to "Float" things.
Now the Progressive Dynamics Wizard... after 20 hours of float. Will kick back up to the higher voltage for a bit just to keep things interesting.. (Also working properly) not all do that automaticall but most 3 stage offer it on the manual menu.
