On my 2014 Leaf SV I put in an Optima Yellowtop and it lasted over 7 years.
Had this issue with the R1250RT - apparently the hot engine means more compression, so need more power to start - after a while the OEM-battery just doesn’t have the punch.
I upgraded the battery to the Yuasa YTX20CH‑BS and it solved the problem.
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 prefer Yuasa.
Yellow top , my recommendation ; I do carry multiple lights on the taco .size 35
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.
I should have bought a yuasa. I bought another brand and rode it hard and two days later it wouldn\u2019t start. I ordered a yuasa since that\u2019s what was in there.
One day my alternator went and killed the optima battery
DO NOT buy a red top Optima. They haven't been good or worth the price in like 15 yrs.
