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 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
Red optima battery on my 93 integra 10 yrs old still starts.
FWIW, my post is the top one, I did not go with an OEM battery after reading through other threads where users had issues finding one in stock and instead went with the Optima YellowTop that was recommended on their site. I have had zero issues.
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.
My last Optima was outlasted by a Sears Die Hard.
Optima was once a great battery. However a few years back they moved their production and since then its been a nightmare of failures.
