I want to replace the batteries on my boat before there is a problem. I know I want the sealed batteries that don't require adding distilled water every month or so. Problem is, I'm a car guy and don't think the Optima battery would turn over a diesel for very long. On my 460 I've got two batteries in a box at the front center of the engine room under the ladder. I know I need to see if my new charger is compatible with the new batteries. But which battery and what size will I need? AGM or gel? What lasts longer? Shipping a battery that size has got to be a pain so do I buy local? I want two to fit in the factory location and that they don't require anything but opening the box and remove/replace.
