Battery OPTIMA or OEM KIA

My red top from 08/09 finally let go last week it has already been replaced by another red top. Highly recommended.

I remember this very interesting post a couple years back regarding AGM batteries and their charging requirements: On the one vehicle that I modified the charging circuit to run at 14.7V I have an Optima Redtop battery in it that has never been replaced. And this includes repeated discharges to near 0% SOC when the sales people at the tradeshows forget to turn the vehicle off after the show.

I always hear people talk about issues with newer Optimas but my old REDTOP is going on 13 years old and still going strong.

i have a optima red top in my drift car. its been in the car for atleast 4 years. 3 of which i have owned it. its been crushed, deformed, on fire and drained dead multiple times (always when diagnosing electrical issues or wiring up lights) and it still works great. it sits in my car hooked up and unused for weeks at a time with no issues.

I have a pair of Optimas (older) and they're dead-ass solid.

They’re pricey but I’ve always sworn by Optimas

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.

Optima has been garbage for about a decade now, ever since they were bought out and production moved out of the country. Quality immediately took a huge dive.

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.
