Reading another post I see that tenders are not recomended for Optima Batteries??

Is that correct? I've been using one for 6 months and don't want to kill a 130.00 battery.

I've been using one on one car for four years and another on another car for two years and the batteries seem as strong as new. I'm happy with them.

don't believe all you read here, some are just opinions. go to the battery tender website and you will find out they are fine for optima batteries.
 
For me NO tender--or other charging--even if it sits all winter, just generator while driving = 7-9 years for regular batterys, and so far 14 years for Optima--and still going --thriving on neglect.

Ask people that use tenders how long they get from their batterys, then make your own choice.
 
I don't use a tender on my regular batteries. I just disconnect the battery, then start them once a month during the winter.
 
The problem with lead acid batteries is once they are discharged and not enough electrolytes are in solution, they freeze in the winter. When I just happen to not drive my cars as much...I was taught that freezing destroys the plates quickly. I assume Optima batteries don't have that problem without liquid solution.

I use an old charger in the barn every few weeks to put a charge on them. Some of my old cars discharge the battery slowly (clock?). My Ford Bronco, on the other hand, sits through the winter and starts right up every spring. Still has the Sears Diehard battery that was in it when I bought it in 2002.
 
I have no Idea what my problem was: first winter disconnected my opitma, it wouldn't hold a charge that spring. Contacted Optima, they said don't allow battery discharge below 10.5 volts. Added a battery tender. Following spring, battery wouldn't hold a charge. Went to acid battery, no more problems. I use tender on cruiser, one on tractor, no problems
