I bought one earlier the year, p/n 3121. Works for me. You need to use one of the low amp/mantainer chargers. I don't have an electric water pump(pure stocker), so all it does is start the car. I've made 8 runs at a test&tune, no problems. If I knew about the Deka, I'm sure I'd would have gone the route.
