One day randomly about 2 years ago, I went out to my Raptor to run some errands. Remote would not unlock doors, no chirp, had to use key to get in. Opened door, no lights, nothing on dash display. Put key in, turned it.....NOTHING. No clicks, nothing. Dead as a rock.
Jumped it with one of those emergency jump packs. Honestly, I didn't think it was big enough. Hooked it to battery, got in truck, turned the key, started right up! I was shocked. Drove it around on errands that day. Started fine all the rest of the day.
That was 2 years ago. It never did that again. I didn't get a new battery. Just a weird fluke. I wouldn't run out and buy a new battery, especially if you already had an Optima AND it was only 2 years old. At least give it a couple of days or a week and see what happens.
