A 1 amp trickle charger shouldn't be able to bring 4, 6 volt batteries to 14.6 volts.

Is the shore power cord plugged in ?

Yep, you would think not. No for sp. Only one plug

So has anyone used this unit, if so did it preform as advertised? I don't really see the need in equalization ever 21 hours but since it is only 14.4vdc for 15 min it shouldn't be a problem.

My WFCO 8955 is suppose to charge at 14.4vdc, 13.6vdc and 13.2vdc with no equalization. It never changes from 13.6vdc which is why I am considering the change.

Is that actually correct? Never heard of that until now but wondered if there was a downside!

That brings me to my next question....it is normal for these converters to hum when plugged in? It hums at all times.

Thanks!
Not sure about your particular unit but... Inverters hum when in use. However, when on shore power, you do not need an inverter. Inverters convert DC to AC. Only need to run inverter while using the batteries.

I keep mine plugged into a 30 amp at all times when at home. Been doing that for about 30 years to many different rigs. In the last DSDP that we had for 13 years the OEM batteries lasted 10 years and had never been equalized.

The "downside" is if the electrolyte level is ever allowed to drop below the top of the plates the mineral oil will ruin the battery.
(IMO if adding mineral oil was a good thing... new batteries would come with mineral oil already in them).

I just replaced my 4 wet cell batteries out and installed 4 full river AGM 6 volt house batteries. I always keep it plugged in to power while parked at my house.
Should I turn off the batteries bank and/or turn off my inverter/charger while it is not being used?
The new batteries were expensive and I don't want them to have a short life because I'm doing something wrong.

If you add the oil the levels DON'T drop.

If battery manufacturers put oil in them, they'd sell a lot less batteries.

Just think about that for a minute..........

I've got a couple of those free meters and have found that they read differently from each other. I'd betcha your batteries aren't actually at 14.6 volts.

On the OP's question, there's a decent chance his older charger will damage the batteries if it stays plugged in day in and day out. He would definitely have to monitor voltage and maintain the batteries' water levels. I would not leave the frig going, not sure why some people think it's a good idea to do that.

It's normal to hear the hum, especially on older convertors.

It shows 6.6 on single six volt. And 12.9 on the 12s..

Ill check it against 2others I have.

And no, they aren't 14.6 when not on charge. They show about 13.5 when the timer is cycled off.

Ill see what the onboard monitor reads at the same time.

If you have a newer 3 stage charger you can leave plugged in. Would check fluid levels at a minimum monthly.
