Over the years, I have purchased three Optima Blue Tops for our 2005, 19-foot Bambi.
Optima #1 is eight years old and still going strong.
Optima #2 failed after four years.
Optima #3, which was #2's replacement, is three years old and is still in use.
Our Bambi still has the OEM converter installed, along with a marine battery isolator switch. In storage, shore power is connected 24/7; and the battery switch is set to OFF to prevent overcharging and boiling the batteries dry, and to eliminate phantom drains. Then, once a month, each battery is charged separately using the converter, by selecting it with the battery switch.
