Battery OPTIMA or OEM Subaru

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My red top from 08/09 finally let go last week it has already been replaced by another red top.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

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.

My battery keeps dying if I dont use my car for 1-2 days and Subaru is failing to address the issues.

I also have an 18 and replaced factory with an Optima Yellowtop. Did not last long at all which sucks, was excited to try a battery I've heard so much good about. Went back to OEM since I didn't want any headache and it lasted me quite a bit the first time. Seems like Optima has declined in quality over time.

Replaced my OEM battery with a yellow top and it lasted less than a year. Complete junk imo.
