FYI, the CTEK line will also desulphate a battery. BatteryMINDer looks like a decent product as well. I just felt more comfortable with the CTEK line as they are well reviewed and supply rebranded chargers for BMW, Lamborghini, Audi, Chevrolet, etc.
Setec, before seeing this thread, I did exactly as you suggested and used the CTEK charger to pad my order to get to free shipping ... great minds think alike. :laughing: I got the CTEK 4.3 in last AGO order. Haven't even had a chance to crack open the package so I can't give my opinion on it...
