Plug in

[woody62]

Hi everybody, I have a 2011 Grey wolf trailer and im wondering if it is okay to plug the trailer in while not in use. Im assuming once the batteries are charged they will stop charging. Right now Im plugging in for 2 weeks and then unplugging for 2 weeks. Thanks Ian

Depends on which converter you have and which battery type. (I looked at the trailer specs and they don't say). I would bet that it has a WAFCO or Progressive Dynamics multi stage charger and deep cycle led acid battery.
If it has a AGM battery you do not need to plug it in to charge until a day or so before you will use it unless there are phantom/vampire loads and there should be a disconnect switch to kill those.
If it has conventional led acid batteries you will need to pug it in periodically and monitor water level in the battery.

If your converter is made by Progressive Dynamics and is a model number 91XX (XX is the amperage), you will need the Charge Wizard accessory (only around $25-$30) for it to function as a multi-stage charger. If your model number is 92XX, the Charge Wizard function is built into the converter. Our 5th wheel was built with a PD9180 to which I immediately added a Charge Wizard.

Can't comment on the WAFCO - I'm not familiar with it.

If all you have is a single-output converter, you can boil your lead acid batteries dry and ruin them in very little time (as little as a week) if you leave it plugged in.

Hi I have the Wold friendship co LTD converter WF -8955 and deep cycle batteries. Ian

Hello all and thanks for the help in advance. I don't mean to hijack the thread but I am dealing with exactly the same issues. I have a new trailer with two group 24 golf cart batteries and also have been doing the plug unplug routine. I have a WIFCO 8955PEC converter/ charger. What is a PEC? I can't find any specs. I would like to leave it plugged in full time.

As mentioned previously, you need to find the specs and determine if the converter/charger is multi-stage or not. If it's a single stage you will boil the water out of the batteries, I speak from experience. A good multi-stage will provide a higher current charge if you have lots of lites on or the batteries are low, As the demand decreases the current will cut back and once there is no load it will drop back again to more of a trickle charge to keep the batteries topped off. But you still need to check the water (if conventional lead/acid) level once in a while.

From another Forum...

-------------------------------

A quick search on Google and then WFCO's website found the spec sheet for this unit.

It is a 55amp conveter/charger, as suspected there is no inverter built in and it is a 3 stage charger. You're good to go. This should do a great job of keeping up your batteries in storage. You still need to be sure to check the fluid level in the batteries at least once a month if left plugged in.

I found all the Spec Docs here. Note the correct Company name of WFCO - very well known - if that's part of the search issue...
