Threw a Duracell 12v in my second gen Honda Insight, and it did fine for the six additional months I had the car.
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 got an already fully charged duracell battery at my local Batteries and Bulbs location in California. Works like a charm just needed to get top posts for it to work in the i3.
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.
At 126,000 miles in 2016, we had the battery replaced with an Optima yellow top dry battery. It lasted around 2 years and was replaced in September of 2018 under warranty. Today, my car suddenly wouldn't start, and after getting a jump and going to Autozone, it showed the battery had zero charge. They didn't have another yellow top, so I got a wet battery, one of the only ones available. What sucks is I checked the warranty date and it expired 4 days ago. I'm quite disappointed that the average life I've seen with these are under 3 years.
my optima red top died after 3.5 years and 4800 miles. When it wasn’t driven, I had the battery disconnected. For a $240 battery, I’m extremely disappointed. FWIW, the battery was in a restomod 66 mustang. I bought it in March 2018, and the warranty expired in March 2021.
Optima used to be a big name but they switched manufacturing to Mexico and ever since they just don't hold up.
