Not true, at least in my case. My wife and I went for a ride last Sunday [both have 2013 STS] both started right up in the garage, stopped and put gas on, started fine again. About an hour ride to our destination and when we going to leave hers was completely dead. I tried my jump pack, wouldn't even turn it over. Long story short, I ended up taking my month old battery out of my spyder and putting in hers to start it and then I took it out and reinstalled the dead one, While it was running. Wasn't sure if this was going to work but it did, ran just fine until we got back home. Put my load tester on it when we got home and as soon I hit the load button it killed the motor instantly. Putting in a new one Today.
