Is Optima a good brand?

I"m considering THESE AGM for my EV conversion in the future.

WaxyChicken -

I heard that they *used* to be great, but the quality has gone down a bit.

I am sure that others will chime in with better knowledge.

When my car battery fails I am curious if an Optima would be a good replacement.

For almost half the price per watt hour you can get Trojan batteries and those are for sure good batteries, the most common size is the T105 that is used in golf carts so they are also used for larger electric cars.

Optimas are good but Trojans are better. Trojan's been in the traction battery business for a long time; Optima's main gig is rough-service and all-position mounting capability.

The Optima won't require any maintenance either. The Trojan's will require occasional checking to top off the water level I believe. Personally, I'd definitly go with the Trojans, but I'm don't know a ton about this kind stuff.

the red tops are pretty crappy, they used to be the best. Friend of mine put one in his Delorean since it is sealed.. worked great to crank the car over but after a week of sitting the battery was dead! He figured a parasitic drain... nope. Put in a regular non sealed battery and it didn't drain after a week.

Okay, I just got off the relevant websites. Trojan's and Optima's size 24s are consistent in every respect: Trojan's better. Their size 24 weighs less and delivers more amp-hours than the Optima. Move to the Marine/RV deep cycle battery and it's not just better - it's way better.

Odyssey, the last name in batteries IMHO..

Althought I bought an Optima red top, I have subs, amps, ect..

I left it on for about 8 hours solid a an excessive
volumn and my truck cranked right over with no problems..

If you do buy an optima, dont accept one thats got a date of 4 months or older, sitting for a long time is bad on red tops, yellow tops are ok for that tho..
marine blue tops are the best of both worlds..

Look into the Odyssey batteries if your going EV..
I got 13 years out of my old Optima and had lots of load on it..

A guy in my truck club SWEARS by the Odyssey and hes not a guy to BS about electronics, he works for DEI and does all sorts of stuff..

I bought an Optima Red Top for my Nissan a few years ago (car was totaled in 2006 ) and liked it. More CCA and about 8lbs lighter than factory unit which was notoriously unreliable.

It's sad to hear they've gone downhill ... unless that is a nonsense rumor.

Those Trojans look big and bulky. I think I saw 54lbs each.

Odyssey batteries look good. Ideally, I want as many CCA as factory (or a few more) but with less weight.
