Fitting 2 Cables onto 1 battery post terminal

[mikepier]

Not for my Explorer, but for my Mom's 2000 Jeep Grand Cherokee, I had to replace the negative battery terminal because it was cracked and could not be tightened anymore. There were 2 cables going into the original molded factory terminal. So I purchased a standard replacement terminal, cut off the old terminal, stripped the cables, and clamped down on both cables one on top of the other. They are tight and not going anywhere for now, but is there a better terminal for this application? It seems most of the battery terminals they sell are mostly for 1 cable. I did buy the Heavy Duty terminal, but that was actually too big, the cables slipped out, so I returned it and got the standard one.

The correct negative cable for the truck can be purchased with the 2 cables attached. Any autoparts store worth their salt will have one in stock.
The clamp that you put on is basically made for a temporary repair. The cables in the clamp will oxidize over time and corrode, and you will have to fix it again or replace the cables.

Stereo shops will carry a terminal that has the place for 2 wires. They use Set screws (big ones) to hold them down.

When I was still running a wet cell battery we would get corrosion on the cable ends. I would just put liquid electrical tape on the end of the wires once I had them in the battery terminal and it would keep them clean.

The other way is to use a marine terminal on the battery and then grab a grounding lug from a home circuit breaker box. This is what I use now..

Ground lug.

Marine terminal

We now run gel cell batteries (AGM) and since switching we no longer get oxidation on the cables. If your in a more humid climate I'd put liquid electrical tape on the end of the cables and on the ground lug to keep them out of the air.

Thanks for the suggestion. Would you know the name of this 2 terminal lug that the stereo store would have? Or pehaps a link?

Stinger is the brand I remember using.. its been years since I used a store bought one.. I've been using the ground lug method for many years now.

They make positive and negative terminals.. and they have them for different wire configurations. Some are 2 wires, some are for 3 and there are others too.

Here is one on ebay..

Anyone have experience with "QuickCable" cast-copper compression terminals? Read an article for them yesterday.
