If you have a batteries plus in your neighbor hood check them out...good price, service, and warranty. go with the agms.

Some Gel and/or AGM batteries require a different charging voltage for optimum life, so you might want to research that requirement to see if it's compatible with what your motor puts out. The reason I mention this is that on some new cars, the engine computer software that controls the alternator output must be tweaked if you change the battery! I personally think a good quality lead acid battery like a Deka is still the best bang for the buck!
