Blue top vs Deka marine

Recommended Posts

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.

No one has a hard on for Optima that actually know anything about batteries. 

 

Dont waste your money on Optima. If you have a sams club membership their Energizer AGMs are really good and not expensive. The group 31s are $179.

too many freq at once, burn the coil, we all know, over 40-50hz, its all coilburning material.
