Gentlemen,
The Optima factory Ford battery that came in my Ford GT was a great battery that lasted over 7 years. The replacement Optima that I ordered from my Ford dealer lasted only two years before it was completely shot. I used to swear by Optima batteries and it is the only brand that I used in my boat and all of my cars. A couple years ago Optima moved their manufacturing operations to Mexico and started using recycled lead, recycled plastics, and battery acid sourced from China. The quality of their product has gone completely to hell. I have purchased 10 Optima batteries over the last three years and all 10 of them have gone bad. One of the two Optima batteries in my boat split and leaked battery acid into my engine compartment causing some fiberglass damage. I thought they were supposed to be dry cell and leakproof? I keep them all on battery tenders but it didn't make any difference.
The representative at my local Batteries Plus dealer told me that the only reason they still carry Optima batteries is so that they can warrantee all of the units that are going bad. They no longer sell them as a high-end battery as they have had such horrendous luck with them. Although I do accept the free warranty replacements I don't expect them to last long and I will never purchase another Optima battery whether it is sold by Ford or through a battery dealer. :thumbsdow
I used to be Optima's biggest cheerleader and one of their best customers. But it is now the last choice I would make and I highly suggest something other than Optima until they get their materials and manufacturing difficulties sorted out. All the best.
