To cut the battery cable teminates off the cable.. Just get some metal cutting sheers.. They sell it at Home depot for like $10.. Cuts wires, metal sheets and so forth.. It took like 2 seconds to cut the terminals off on both my Jeeps..
I then just got 4 new color coded terminals from Advance auto and use a knife to scrap some of the paint off where the cables go in (they overpainted it) and then just clamped down the metal plate to hold the cables on the terminal and walla.. No more loose battery terminals.. The stock terminals are lead so they pretty much once tightend never hold a good grip anymore because lead is so easy to bend.. I had electrical issues on my 4.0 with those looser terminals.. since replacing them hasnt had a issue anymore
