Heavy Metal | F-350 Super Duty Odyssey Battery Install Sooner or later, the unending march of time is going to kill your factory flooded-cell batteries. Sure, you can prolong their life with proper storage and maintenance techniques; but in the end time always wins. That was the issue I found myself facing a few years back with the factory Motorcraft batteries in my 6.4L Powerstroke equipped 2009 F-350. After ~7 years of used the originals were showing the “Red Dot of Death”. All-in-all, they lived a good life. It’s hard to ask for more than service life they provided, but it was time for an upgrade. Over years of motorsports and off-road/marine experience I’ve come to trust the Odyssey brand of AGM batteries. They can be somewhat expensive; but they deliver massive cranking amps, deep draw capabilities, can last over a decade, and are tougher than a $2 steak. I’ve been using one of their power sports batteries for well over 10 years in a Jet-ski and it has never let me down. So picking up a set of Odyssey AGMs for my Super Duty was a no-brainer. The "Red Dot of Death" signifies the end of life for this particular battery. Acid leaking around the post has done a number on the terminal finish too. Interested in knowing how to correct that? One of the most interesting things I noticed about the Odyssey Batteries, it just how much beefier they are than the factory equipped units. It’s instantly apparent as soon as you pick one up. Even though the AGM Odysseys occupy the same amount space, they outweigh the Motorcrafts by nearly 12 pounds each. That’s a lot of extra lead, and goes to show why Odyssey Batteries tend to have such a long life. That makes them perfect for my F-350 where an extra 24 pounds isn’t really going to make any difference (it already tips the scales at over 4 tons). The factory equipped Motorcraft batteries couldn't even muster 9 volts. This install actually took place about four years ago, and the Odysseys don’t show any signs of giving up. Though they were fairly expensive I wouldn’t hesitate to buy them all over again. If you have an application that requires an insanely tough battery that you expect a very long life from, I high suggest you shop Odyssey. This set has done everything from jump start an 8 second drag car to power a kegerator in order to provide the cold hoppy nectar of life on a hot South Carolina summer day. I’d buy them all over again, they’ve been well worth the money. American Made Quality in a rugged package, what's not to love? If you’re interested in picking up check out the link below: https://amzn.to/31FKShh Fresh out of the box the Odyssey Batteries were putting out 12.76 volts. No light weights in their own respect, the Motorcraft units weighed in at 42 pounds each. But at nearly 54 pounds, the Odysseys are clearly the heavy weight champs. It looks good under the hood. It's a good idea to make sure these things are mounted securely. The CAI required a little extra work to get everything set up on the passenger side. Be sure to mark your install date.
