i just got a brand new optima deep cycle yellow top battery for my T4R and i doesnt exactly fit.... is there any way i can keep it in place so it wont slide off or tip under my hood?
I recently got one and I had to lower the nut that holds it to the fuse box and then move the bolt on the front to a bolt closer to the passener side. Then just wedge something in that will hold it.
As was stated they do make a spacer for the Optima. Personally I just used a few of the rubber coil spring spacers and they work fine. I messed up and didn't realize I needed the reverse terminals, but Optima clearly states the battery can sit in any position, even upside down, so I just laid mine on it's side and it has been fine for the last 3-4 months.
Instead of laying it on it side I could get enough stretch out of my negative terminal, I just had to more the small piggyback ground. For the positive cable I bought a foot long battery cable at advanced and bolted it as an extension and wraped it in electrical tape.
