Optima....... :wallbang: High price + low quality. Match made in heaven. Thundra04struck has the right idea.I got an Optima Red top about 2 years ago and am quite glad that I did. The OEM battery was showing signs of corrosion on both terminals and was actually eating away at the top support clamp/bracket/brace. They are a bit more expensive, but they are maintenance free, sealed and will not corrode like the OEM battery did. I've had no issues at all since I made the switch.
