As suggested, get a battery charger. The smallest is best. A "Battery Tender" is a motorcycle specific charger and many folks swear by them. The Tender will come with proper leads and are color coded with excellant instructions for the uninitiated. You can get one on-line or check out your local bike shops. The package also includes a cord to be permanentely attached to the battery so you don't have to remove the side cover. Just leave the other end(2 or 3 inches)hang out from underneath the side cover. Both of our bikes have this feature. It is great if the battery is run down or the bike sits idle for a long time. The Tender will maintain the battery at full charge and is fully automatic.
