New Optima Battery DOA (almost); And Getting Worse

Companies who sell chargers with "gel/AGM" settings may like folks to think that they are one in the same, but they are not, even though many folks use the terms interchangeably. Gel batteries are rarely found in automotive applications and are more typically found in stand-alone power systems, wheel chairs, etc... Optima batteries are AGM lead-acid batteries and can be treated and maintained just like other lead-acid batteries, but using any charger setting with "gel" in it may not fully-charge non-gel batteries.
