I would get the latest Nuclear infused ultra titanium battery. Some people are saying that these batteries will last like 12-20 yrs, and could be used from car to car. They have like a inversion check valve that never allows the holding charge to draw them down.They also have twice the normal amount of acid in them compared to a normal battery. They crank out at like almost two thousand cranking amps. If your going to get one...I would get the green one with the side glowing illumination, they look awesome at night.
