The battery in my 2009 Kawasaki Ninja 650R died on me just before winter. I need to winterize my bike and get a new battery. Is there a battery that is preferred to use in my bike? Also what all do i need to do to winterize my bike? I just got it in April so im not sure what to do.
There isn't a preferred battery for your bike, if you are talking brands. There are preferred brands on this forum, as you can see. Invest in a battery tender, and considering your bike, you probably aren't super worried about excess weight, so you'll probably go with a standard battery. you can pick up a battery at cyclegear or shop around online. you can either match up the CCA from your current battery or just look it up online.
your battery might still be ok, you need to test the voltage. any pepboys or autozone will do it for free. if it's below 12v toss it (recycle).
I personally prefer lithium, but I'm into weight savings and a longer lasting battery. It holds the charge longer also.
Cycle Gear sells a battery with a lifetime warranty, if you are close to one of their stores.
I have tried Advance and Auto Zone batteries, but they failed sooner for me than the Walmart Everstart.
