Optima is easy, replacements are available on the road, there is many different hold down options available, and they work well. I run EFI, Two Electric fans, Electric water pump, two fuel pumps, and all the other street car crap. My Yellow top is 7 years old and has 5 drag weeks and lots of passes on it, it is doing great. I work for a battery company and I put a load test on it every year before I go on drag week and so far so good. I do load up a spare for drag week but have yet to need it.

If you go optima you will want a yellow or blue top. They are the same battery but different layouts and warranty. The yellow has top and side posts and the blue has an automotive post and a 5/16th stud because it is designed for marine use. While the batteries are the same under the cover they carry different warranties, the yellow has a 36 month free and the blue a 24 month.

The downside is of course the weight.
