Slow cranking but starts

[Matthew Jeschke]

I have same problem. JUST bought my battery. I lost my receit though It's an Orielly Super Start AGM battery Hopefully they have me in the system yet for the warranty.

Years ago my C5 Corvette had electrical problems so bad that the ignition would TURN off and motor shut down going down the interstate. I couldn't figure out for the life of me what it could be I went through a TON of stuff. Turns out the new battery was bad and causing that much trouble.

Likely is the battery but I would still check voltage drop on the cables. Check for corrosion at connections and loose fittings. Basics first.
