I put a Braille battery in my Exige about five weeks ago. I've kept a Battery Tender JR. on it at all times since then while it's parked in my garage as I typically drive it every couple of weeks. The tender's light is always solid green.

Three weeks ago, when I took the car on a three day road trip to take a class at Infineon, I had trouble starting it the morning of the second day and had to be push started twice on the third day. I was driving at least 30 miles each day on that trip back and forth from the hotel, so the car wasn't just sitting.

After the trip to Infineon, the car sat until today when it wouldn't start. It had accessory power, but the starter wouldn't even crank. It had been on the tender (with a solid green light) up until 45 seconds prior to starting it. I put the stock battery in for the hell of it and got the same result, but it had been sitting on the floor of my garage the whole time so it could have drained.

I put the Braille back in, spun up the Mustang and jumped the Exige, which started right up. I let it idle for a minute or two, shut it down and tried to start it again. It did, on the first crank. I tried one more time and it again started on the first crank.
