Not enough in what way? 650 ca is adequate but maybe there is something wrong with the batt. Could have a bad cell. Have you done a load test?so what is the preferred battery of choice for your FJ?
Cranking amps, etc...
I bought a new one with 650 CA and it doesn’t seem to be enough.
Same story with me. USA Plant closed for good Jan. 2009. Another Johnson Control , cheap labor and no worries on pollution , so they can use the Optima name and then let quality go... And reap the rewards.When Optimas first came out, I bought a red top. That one lasted for 10 years, so when I needed a new one, I got another Red Top, it lasted 6 months...absolutely a sorry battery. Like everyone else says, stay away from them, they are not what they used to be.
Save your money, I went thru 3 in 8 months. JUNK!!A free battery is always good. For dependability, get the one that Consumer Reports recommends. It seems they have a different one every year. Lately I have been getting mine at Costco because of the warranty.
I always wanted an red top Optima but never can convince my self to purchase one.
