I’ve had mine in for about 3 or four years. The only thing I’ve noticed is I don’t have to change my battery every year now.
I had an Optima battery in my 2006 WRX for about 7 or 8 years before deciding to replace it with another Opitima battery. I ran that second Optima battery for about 5 or 6 years before trading in the vehicle towards a 2021 WRX. The OEM battery may end up turning over just fine when the temperature is -20F'ish, but Optima batteries have never let me down in the past.
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My red top from 08/09 finally let go last week it has already been replaced by another red top.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.
The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.
Haven't been impressed with the quality of optima over the last 5ish years.
Have two red tops in my 05 GMC. Sneaky suspicion one is bad. They were new when I got the truck six years ago.
Went to start truck after sitting five days and it was dead. Meter showed 12.1 and it charged in an hour which is very fast. Truck would turn over but not run. Checked charge again, primary at 12.4 and secondary at 12.7. Swapped places and truck starts, runs, all accessories work now.
Stay away from optima batteries unless your car specifies an AGM battery because they can be very problematic.
