How well does the YTX9-BS OEM battery do in the cold?
I had to replace the YTX9-BS in my 2010 before I could use it below freezing. I replaced it with a KMC replacement that lasted 2-3 months. The KMC battery was rated for 170 CCA but struggled one the temps dropped below 0 C. I was lucky to start the bike at -6 C. I was wondering if the YTX9-BS performs okay below freezing. If not, what replacement would you recommend?

Battery size doesn’t matter in cold-weather performance. It’s chemistry that counts and LiFePO4 lithium-iron batteries don’t lose power as much as lead-acid when temps drop.
Can’t go wrong with Shorai or Yuasa lithium-iron battery in YTX9-BS size. |

Lithium ion batteries are superior to the stock lead batteries. They may cost more but they are supposed to last 10 years. AND they weigh much less and take up less room in the battery box. I recommend a battery tender for any battery. One of my battery tenders does both lithium and lead batteries. I will be getting one for the 250. I have one that was in my 600 and now lives in the 400. This will be my 4th season with it.

I will answer the unanswered question.
The OEM battery for 2010 Ninja 250r (Yuasa YTX9-BS) does fine in cold temps, even -8 C. |

How many amp hours does the YTX9-BS (or the lithium batteries in general for motorcycles) have when compared to traditional batteries? Sometimes ill have my motorcycle off but drawing power from a USB device. Would love to get one of my bike but I don't wanna sacrifice amp hours

Depends upon how long you leave it off. Lead-acid has self-discharge and if you leave it off for 3-months, it’ll be completely dead even without any USB accessories powered. It has zero excess capapcity for that time-frame. Li-ion can go for a year with bike off.
Due to cost differences, it may be more cost effective to buy a new lead-acid battery once a year than going with li-ion. Maybe if you’re racing, that 9-lb weight savings may be worth it. |

Weight
I weighed the stock battery of my 400 and a Walmart battery, both weighed 6.4 lbs. The lithium ion battery I have is less than 1 pound. So if most lithium ion batteries are a pound or a little more or less, you are saving close to 6 lbs.
So if you go with a full exhaust or just a slip on, you can drop 5lbs conservatively. AND a lithium ion battery that’s another 6 lbs. That’s 11lbs, that’s pretty good weight savings for the 250! |
