General consensus is that the yellow top optima battery is best. Also, the optima is the only aftermarket battery that has the vent hole in the same place as the OEM battery.
I have the Odyssey Yellowtop
I found my first optima red top. It was dead when I found it. I just happened to have an agm battery charger/restorer. It took three days of sitting on the machine reconditioning, and then a day or so of charging afterwards. It held a charge forever. It was made in 05 or something like that, and it ran great until this year. I have since replaced it with a new one, and it works great as well.
I have an optima red top 34/78. Its incredible. Been almost 3 years in and no matter how much I throw at it on the trails I dont get dead cells. The individual gel cells are less perceptible to shake damage from rough terrain.
I’ve got yellow top optima. Hasn’t failed me yet :)
I put that same Optima in 6 years ago (to the month!). Mines still fine knock on wood
I have an optima, have had others, love them. The only issue I've ever had with an optima is getting a severely discharged battery to take a charge, but through youtube i figured out it was an issue with my charger and started putting another one in parallel.
No they are garbage now. Source: we sell them at work. We also warranty them. Don't buy an Optima. Ever since Johnson bought them, they went downhill.
I've never been impressed with an Optima battery.
I used Odysseys PC-680 on other cars, particularly on Evos. They weight about 15lbs and they free up spaces dramatically but the reliability is awful. I went through 3 of them once. They will start the car with a little bit of difficulty but don't try to start the car with the A/C , the radio etc because they can't.
