Just came back from a trip. Left the car for about 3 months and I'm pretty sure the think is dead. No lights or anything. Tried to give it a jump but nothing happened. Read online that a completely dead battery has a hard time being jumped. What are my options now? Do i need a new battery, is there a battery charger that can charge it, can i take it to someone to charge it up? I am thinking about getting a new battery though, whats the best out there?
What to do with a completely dead battery?

I once had my battery die to the point that I couldn't jump it either. I bought one of those portable chargers and hooked it up for a bit and waited and it fired up after that. Still going on that same battery too, at least 3-4 years later. It's come in handy for myself and to jump other people's cars since.
I have this one, but I think I'd get the air compressor equipped one for $25 more. [Dead Link Removed]

I would think so. They just have a small battery inside, so I guess it's like putting in a new battery without taking out the old one. The issue with not being able to jump with another car might just be their battery is too weak to power that car and start yours from dead.
Or maybe me leaving it connected for longer is what helped because it charged the battery up enough that it was able to start.

I had that problem once and a regular boost would not start it. I hooked up a standard battery charger and left it charging all night and it started fine the next day. My car had been sitting for a couple of months. Since then if I am away for an extended time (more than 1 month) I hook up a Battery Maintainer and that solved the problem.
A completely dead battery is harder to jump simply because you have to get the charge up to a minimum level for the car to even crank. You pretty much would have to leave to cars connected for longer to keep charging it. What car are you jumping the FX with? If it's a smaller car with a small alternator, it may not have enough current to even start the FX. I tried jumping my FX with a 4 cylinder once and even after leaving it connected for 20 minutes revving it up, it wouldn't start. Then our building's handy man brought his V8 Titan down and it started on the first try.
Ah okay, was using a Lexus RX didn't do much. Had a Toyota Tundra connect to me and gave me instant battery. Not enough to turn over so I'm still currently waiting.

Haha, I tried to jump with an RX330 as well and no luck.
Yeah gave no life at all. After a hour with the Tundra it worked. Probably could of taken less time but I kept trying to turn it on. Took it out for about a 30min drive or so. Hopefully it last long enough. Bought the Stanley 500amp peak 1000amp with air compressor just for back up.

I did notice after getting back in the car and starting again it has a little trouble starting. It does that starting sound for a little bit. Not sure how to describe the sound but with cars that use a key ignition and you turn the car over. It seems it's doing it for a bit longer then normal. I assume it's a low battery thing?
