Re: Who's still riding? (Fall & Winter 2018 Edition)
Those fancy lightweight batteries are lithium, they're maintenance free and you can leave them in the bike over the winter. It will start up come spring with no issues.
I used to just disconnect the battery and take it upstairs to keep it out of the cold. Then I got lazy...
Last couple of years I just left it in the bike. When it comes time to start it in the spring, it usually has enough juice to crank. If not, it's a bike... As long as it still lights up the dash, you can just push start it and go for a ride to charge the battery. If I had a fancy lightweight battery then the tender and all would make sense but otherwise it's more hassle than it's worth.
If you're really concerned, just take out the battery and store it somewhere in the house. Guess how they sit in storage before you buy them...
