Any special way to remove dual 6v batteries

jquarles · 10-17-2010, 06:56 PM

I was getting ready to remove my dual 6 volt batteries. But as I stood there wrench in had, it dawned on me, I don't know how. Question to all of you with two 6v batteries: Does it matter how you remove the cables? Positive first...negative first...disconnect the jumper wire between the batteries????

The last thing I want to do is harm my system. I just these sixes put in back in May so I havent' had to do this yet.

I think many of us have used this. This was the first link to it that I found with google.

Thanks.

From what I gather there, I remove the negative from one 6v battery. I assume this is the negative for the trailer and not the negative that just goes to the postive of the other battery.

Then I remove the positive. Is the the positive off the other battery or the one off the first battery or the one that goes to the trailer??

The attached diagram has my assumptions. The numbers represent the removal order, the letters are just label so speak to. In the diagram, I remove in order, D, A, C, then B

Yes? No?

Think of your two 6v batteries as one 12v battery, because that is exactly what they are. The wire that goes in between them makes them that way, so if you mentally eliminate that wire in your mind, you just have 2 remaining terminals, both going to the trailer. Those are the ones that matter.

In your diagram, remove wire A first, then wire D. The order of the remaining 2 connections (the wire going in between the batteries) doesn't matter.

One of the terminals is connected to the frame. That is the first one removed and the last one installed.

The reason is that way if your wrench accidentally touches the frame while touching the hot lead then you don't send sparks flying every where.

You do not want a short circuit.

Good point PopBeavers!

[QUOTE=Barb&Tim;76448]ShrimpBurrito's method is as good as any.

Order of connection or disconnection really makes no difference. Once you remove any of those connections you have removed 12v power from the TM.

Always remove the negative( to frame gnd) terminal first. That way of the wrench hits the frame while loosening the terminal connection nothing happens. Always put the negative terminal back on last for the same reason.

Not only that, you may blow up the battery...seriously...years ago it happened to me, while tightening something in the battery area on a car. So follow the above instructions. The hydrogen gas produced in a lead-acid battery is highly explosive!
