In most cases, 10 volts is not enough to start a motorcycle. Motorcycles typically have a 12-volt electrical system, and the battery needs to provide sufficient voltage to power the ignition system, fuel pump (if applicable), and other electrical components.
When starting a motorcycle, the battery needs to supply enough power to engage the starter motor, which requires a significant amount of current. If the battery voltage drops too low, the starter motor may not have enough power to turn over the engine, or it may turn very slowly.
Ideally, a fully charged motorcycle battery should have a voltage of around 12.6 to 12.8 volts or higher. As the battery discharges over time or due to various factors like cold weather or extended periods of inactivity, its voltage will drop.
While a motorcycle may show some signs of life or attempt to start with a battery voltage of around 10 volts, it's usually an indication that the battery is significantly discharged and needs to be charged or replaced. It's best to have the battery charged fully to its optimal voltage or replaced with a new one to ensure reliable starting and proper functioning of the motorcycle's electrical system.
If you're experiencing starting issues or suspect battery-related problems, it's recommended to have the battery tested and checked by a qualified mechanic or use a battery charger to restore its charge.
