Wfco replaced today. Will get data in a few weeks..

converter won't come out of float while running lights and furnace, unless the power draw is heavy enough to cause the voltage to droop from the converter, then charge mode will kick in

as for the periodic equalize boost mode, this will only happen during periods of NON use, with fully charged batteries in storage, and you would need a voltage recorder to catch it

Thanks... I posted before I read your reply.... lol

... That's why I'm not an amp hour meter fan. They're too complicated for us common folks, or alternatively, it takes too much time keeping them accurately representative of what state the battery really is in.

In keeping with K.I.S.S., I just use a simple voltmeter and a simple hardwired-in amp meter to keep an eye on the RV batteries.

But what about the float mode question I asked? Any reasoning to it?

Are my batterys so fully charged that it will take a larger amp draw to get it out of float? If its normal Im fine with it... Just asking is all...

It's all about what the batteries want, not what people want or battery recharging device manufacturer's want.

"Is he hungry?"

"Dunno. Is he reading? What color socks is he wearing? What kind of car does he drive?"

;) A good metering system can tell when a battery is laying back with a satisfied smile on its face or sitting there with its tongue hanging out. But it cannot see what's in its stomach.

When you suspect a converter or charger reading is growing a long wooden nose, you have to verify it with a hydrometer or play the part of a pipe organist and start tweaking the voltage. Like petting a strange dog. If he wags his tail, he's happy. If he takes your arm off, then you guessed wrong...

Amp hour meters need periodic re-zero-ing and with a sealed battery that means twirling knobs and poking a stick at the battery. Wet batteries are easier.

David, maybe the proper term should be TRICKLE TRYING TO CHARGE.

When moving from the liquid battery world into the AGM battery world the situation is different. Once my RV batteries are fully charged, I've not found any charger voltage that will continue to drive 1-3 amps continuous into them. They just sit there refusing to accept any more current.

Maybe it takes bubbling battery liquid in order to sit there and absorb 1-3 amps continuously?

(On it's "2 AMP" setting - my ancient Sears charger is only trying to be a trickle charger when hooked up to our RV's AGM batteries.)

Just a question here... My wfco did it too..

I did some work in the camper by removing the top bunk and making shelfs here..

With that said the PD 4655 is in float mode, and has been since it went into this mode whenever....

I had the heat on during my renovation.( Its 26F here in NJ)

I dont think the voltage drop with 6 led lights on and the furnace went lower then 13.1 -13 volts from my meter reading at the batterys...

It stayed in float mode during my 3 days of putzing around in the camper..

Should it come out easier? Is this normal? My wfco did it too. stayed in float mode..

If I remember correctly the wfco came out of float when I winterized the RV and ran the pump to suck up antifreeze...

Is there an algorithm to this?

Also since I have no way to know what time this goes into equalize mode at the 21 hour mark I have not seen this either..

I don't know how I would know other then being at the right place at the right time...

Thanks all..
