The battery in the Yamaha Vstar 650 motorcycle is a 12-volt, 14-amp-hour battery. This means that it can store up to 168 watt-hours of energy.
If the motorcycle is not used for a long period of time, the battery will eventually lose its charge. However, the motorcycle's charging system will automatically recharge the battery when the engine is running.
To ensure that the battery stays charged, it is important to ride the motorcycle for at least 30 minutes every week. This will allow the charging system to fully recharge the battery.
