Default Don't Blow Your Battery Tender

I blew my Battery Tender by starting the car with it still hooked up and powered. I suspect a diode blew inside of the Battery Tender from generator current. To avoid this, simply unplug the Tender before starting the engine. Luckily it was still under warranty and a new one is on the way.
