I have a pair of Optimas (older) and they're dead-ass solid.
They’re pricey but I’ve always sworn by Optimas
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 :)
Used redtops for years. Had a couple go bad, but 3 year free replacement warranty solved that.
I'd be more concerned about the Optima battery - they have been crap quality for years now. Probably better than VW OEM junk though.
Purchased one a few years ago, bad a year later and yes I have a good battery tender.
The "new" Optima in my RX7 died after a very short life
