kcr357 81 #1 Posted February 12 Going into a boat w 2x 500 watts rockford amps, 1 is an AB, the other is D. Charging system is less than stellar, current wise. Both batts are group 27 and will be dedicated to the audio. The Deka flooded battery https://www.nationwide-battery.com/deka/27m6.php actually has better specs, costs around 130. The optima https://shop.advanceautoparts.com/p/optima-blue-top-marine-battery-group-size-27m-800-cca-d27m/16940024-P?searchTerm=group+27 has a much better rep, thinking I can get it for a bit under 200. Are the bluetops going to be worth it, especially having worse specs? Seems everyone has a hard on for optima, not sure why.
