Many of you know I have been having problems with my batteries since I came back from Mammoth. The Interstate 6 volts that were in my trailer were over 5 years old So Labor Day weekend I replaced them with a set of NAPA 6 volts. I have still had many problems with the batteries not making it through the night, New Years weekend being the worst.

So Ive been reading up on RV.net on my power converter thinking that it wasnt charging the batteries. I have a WFCO Converter WF 8955 AN. Lots of problems with this converter on the net so I ended up calling Tech support and having them walk me through everything as far as what the converter should be doing. So after work last week I was working at the trailer testing the different circuits, swapping out batteries, ect ect...... The converter seems to be doing what it should....

13.2 Vdc “float” mode - Im right at 13.2
13.6 Vdc “absorption” mode - Im at 13.51
14.4 Vdc “bulk” charge mode. Im at 14.34

I almost bought a new board for $160 glad I didnt.......

So back to the batteries. I pulled all the batteries and put them up on my work bench. I charged them one at a time for 8 - 10 hours a piece. The 5 year old Interstate 6 volts seemed to take a better charge than the new NAPA's. So I did some more reading online about batteries and ended up running up to Pep Boys for a hydrometer to check the electrolyte level in all 4 batteries.

The 2 Interstates were low - kinda what I figured for a 5+ year old batteries.
The first Interstate had an AVG 1.225 between the 3 cells which is still okay for use. The other Interstate had an AVG of 1.210 which is on the low/replace side. All cells were even so I know the Interstates did not have a bad cell.

When I tested the NAPA 6 volts with the same hydrometer in all 6 cells and the needle never moved??? Almost like they were filled with just water no electrolyte level at all??? I have been reading up on batteries and converters for weeks trying to figure out this problem I have been having. So last weekend I picked up a couple new Costco 6 volts and so far so good....

Here are a few Pics I took.....

I also picked up a Equus 3721 Battery and Charging System Monitor for $14.Plugs into the 12v plug in the trailer and give a digital readout of what your batteries are at.......

Damn Jeffy NICE JOB!!:dude: I wish I knew you were having problems.

BTW, keep an eye on that Chinese WFCO converter. I have personally replaced 2 of them after they got stuck at 14.4v charge and boil the batteries, both in Gear Box's.

Now it's time to PLAY!!!:boob:

Nice job Jeff... Do you keep the trailer at your house?

Thanks Scotty - After reading everything on WFCO converter I figured I just needed to change out the board but everything seems to be working like it should. Did you replace the WFCO to another converter on the Gearbox's or just swap out the boards??? Did you stay with the 55w if you did??? I was reading you coud swap out the 55w board for the 35w board and the charger would kick in more. I also read you could drop in a PD9260C converter which will slip right into the same slot of a WF8955 - prob what Ill do when this one goes.......

:boob: time :dude:

Thanks D - My trailer is kept in storage and doesnt get very much plug in time unless we are camping at the beach. I have a 6v/12v charger - Im going to start using a little more. I think most of my problems started when I left the battery kill switch on for 2 weeks just before we did Mammoth and it killed the batteries down to nothing. The only charging they got was the drive up and then from the generator that week. I dont think they ever got a full charge - Being they were over 5 years old I just replaced them with the NAPA's thinking I was good to go.... Thats when I really started having problems - Knowing the batteries were new I figured the charging system on the trailer was not working right and thats when I started reading and testing.......

I dont know where the electrolytes went on the NAPA's and for it to show nothing on both batteries is pretty strange also. They dont appear to have been over charged ( I see no boil over on the tops ). I cant find anyone else who has ever herd of this happening so its still a mystery to me....

I would assume someone screwed up when they filled your Napa batteries.

You should look into some type of solar charger and make sure you turn the switch off.. I am spoiled being able to ha e my trailer at home and plugged in all the time..

Napa has never had that problem - Just ask them:ftt:

I like the solar idea but to spend that kind of coin that will have to be on a keeper rig. I like our trailer but figure we will only have it a few more years and then it will be time for another one.....

On our first trailer, we had a battery draining problem, I went out in the trailer one night and started pulling fuses in the dark to see if one would arc,or show a load. I found one that did, It was the refer door heater, relay was stuck closed even with the fridge off, and killing the battery.....Older trailer. Actually i just made this story up. Not really, true story

Ah, if you have the "plastic" faced WFCO so there is a drop in PDI for it.
I've done both the plastic and metal WFCO. The metal one there is no drop in solution and requires cutting and modification to get the PDI 9260 (http://www.bestconverter.com/9200-Series_c_84.html) installed. Also the intelicharge switch hangs outside the panel and lights up the bathroom at night as it flickers away.
If your WF8955 series is the plastic face newer series, there is a drop in PDI 4600 series (http://www.bestconverter.com/4600-series_c_133.html) to make life wonderful for you. Takes about an hour to do (2-3 w/ beer) and the intelicharge is built on the board. :dude: The 4655 is about $50 more than the 9260 but it's worth the money and time savings and the 5-amp charge difference is negligible


BTW... Props for Best Converter (http://www.bestconverter.com/), Great to work with and awesome pricing!

I have the metal faced - If I pull the old board out isnt there enough room to drop the 9260 in?? Randy was out of town when I tried him last week.

Damn! what year is your GB? Fleetwood musta had a shitload of the of metal WFCO's in inventory because WFCO quote making the metal faced units in 2002!!!

You will need to do some trimming of the converter cavity to get it to fit in but the 9260 is this one to get.
