Currently running a yellow Optima, 3 years and going strong. I don't recall what the OE battery was but it crapped out after 2 years in mild California weather.
I had an older optima yellow top last about 10 years. I miss when that quality was available
On my 2014 Leaf SV I put in an Optima Yellowtop and it lasted over 7 years.
I have a 10 year old yellow top Optima (not even the nicest thing out there) that starts a 440 (often 9 months between starts) every time. I haven't even put a tender on it in the last 5 years.
Optima yellow top. It's around $300 ish. The last one was replaced after a decade. The new one I have will probably be the last one.
I have used Bosch, Panasonic, and now Amaron in my 2013 WK2. Bosch lasted as much as my previous 2 Mopar lasted.
Optima seems to be the only brand of cylindrical Pb batteries for automotive use... pretty much every other automotive Pb battery is prismatic.
That's the first I've seen one fail this way.
A few hours later he came back with a new S4 018 Bosch battery (original one was Yuasa HSB056). He assured me it had the same specs, despite being a different brand (40Ah, 12V). He installed it, and then told me it was a “slightly different base size” from the old one.
One day my alternator went and killed the optima battery
I bought a brand new Bosch battery last year ( not Halfords)and when I checked the voltage it was less than 10 volts so there are dud batteries out there.
