Battery OPTIMA or YUASA

If you change the type from flooded wet cell to AGM, you must code the BCM to change the charging parameters.

Bought the Optima, not yet installed. Have had good luck with them, 5 yrs or more each,

My last experience from them was a yellow top from 2015 that I got for my '01 Mustang. Had it for 4+ years starting up just fine and survived despite having been drained dead 5 times or so. Sold the car before the battery died.

I had one. It lasted a good seven years. Still good quality, its worth it if you can swing the price.

My red top from 08/09 finally let go last week it has already been replaced by another red top.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

My last Optima was outlasted by a Sears Die Hard.

Optima was once a great battery. However a few years back they moved their production and since then its been a nightmare of failures.
