Perfect Charge Curve:

Bulk Phase: 200 amp batteries may charge 40 to 80 times. A battery takes more current when it is discharged.

AGM needs different voltages.

Acceptance Phase: Keep the battery at 14.6 v when the amperage is reducing. This will help to restore to 25% capacity.

Equalization: Light bulbs and the electrical object may be damaged by soaring voltage. While equalization, it disconnects all loads. There are multiple stages in manual type. In auto type it is impossible.

Size: Chargers size depends on batteries size. The boats that regularly stay in the port needs smaller chargers.
