Battery OPTIMA or OEM BMW

I like AGM batteries. Using optimas now, whenever these finally die I'll try another brand. 4 years in now and I can't notice any loss of capacity yet. They work amazing when it is like 0 degrees F, too.

If you do need one, optima is pretty good but expensive.????

I have a VR6 swap that Sal at S&P did for me and we used an Optima Red Top.

I've had an Optima battery for several years. Still cranks my G20 van as if were brand new.????

I run optimas because of the extreme temps here. Can be -40 outside and over 120 in the summers. They've been great for my old 454 powered truck.

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.

While I did that I went ahead and grabbed a Red Top Optima Battery. Got everything back together, it turns over great but it doesn't spark.

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.
