OK you genuises, I have a PD9260C converter in my 5ver. Suddenly it decided to start charging at 14.5 volts continuously. When I first noticed it it had my Crown batteries at 112 percent. I unplugged it from shore power for a few days then plugged it back in. Within a few hours it was charging at 14.5 vots and creeping above 100 percent charge. I have a TM-2030-RV batter monitor on the battery.I have contacted Proggressive Dynamics for input but no response yet.Any suggestions?

There actually are two or three possibilities here:Converter went bad.Batteries are getting REALLY weak, causing the converter to think they need the boost charge voltage all the time.A loose or corroded main cable connection, also giving the converter a wrong signal.P.S. How are you determining that percent of charge ?Typically you can't trust a "battery monitor" for a real accurate report.

Sounds like it may be stuck in booct mode. Can you manually take it out of boost? I have a PD9230 and can do that at my charger.

What is the amps draw when the batteries are full and the PD is doing 14.4? (bad cell?--have you checked the batteries?) What is the amps draw when not on shore power--anything unusual?

Is it possible the converter is going into equalization mode? Is it possible that when the TM's base line understanding of 'full charge' was set it really wasn't at 100% capacity and it needs to be reset?

Disconnect from all power. Then touch disconnected cable pigtails together to drain all power. Reconnect power leads. Reboot City...

Disconnected batteries, checked water and specific gravity. One cell was a smidgen low on water, maybe 1-1.5 ounces all cells checked at 1.3 specific gravity and batteries were showing 94 percent charge status before I disconnected them. I discharged any remaining power by touching the leads as suggested and hooked them back up. We'll see in the next few hours if anything changes.

I'll do this today, I want to check them with a hydrometer and check water levels in the batteries anyway and they have to be removed to do so.

Ok, from time to time (after 20 hours on float as I recall) the 9260 is supposed to go into "Equalize/Desulfate" mode for 15 minutes, again as I recall (Times may be off) You might be seeing that.

Then it repeats again in 20 hours, and 20 more hours, and .. eternally.

Yes this is the normal operational mode of the 9260 however, it's not coming out of this Equalize mode. It just stays there all the time at 14.5 volts and as mentioned had my batteries at 112 percent. Which can't be good for them.

Not sure how to do that. I'll have to look at the manual.

Until the rear duals rectify the problem.
