Keep in mind that you can not use one of the ones that has both top and side posts on a C4. I think all years but for sure a 96. Optima has been the standard in the AGM battery's for the last 30 years. I Have at least one that is close to 20 years old. I have also had some that have failed in less than a year. One advantage they have is they are easy to find. Most everybody has them. If you have one go dead be sure to hook it up to another Battery and charge them both.
