If your motorcycle's battery has been sitting unused for five months and has dropped to a voltage of 9.5 volts, it is significantly discharged. Starting the motorcycle with such a low battery voltage may be challenging, as the battery may not have enough power to crank the engine effectively.
It is generally recommended to have a fully charged battery, ideally with a voltage reading of around 12.6 to 12.8 volts, before attempting to start the motorcycle. If the battery voltage has dropped significantly, it is advisable to recharge the battery before attempting to start the bike.
You can either use a battery charger specifically designed for motorcycle batteries or jump-start the motorcycle using another vehicle with a fully charged battery. Ensure you follow the proper safety precautions and connect the jumper cables correctly if you choose to jump-start the bike.
If the battery fails to hold a charge or continues to discharge quickly after recharging, it may be an indication that the battery needs to be replaced.
It's worth noting that proper battery maintenance, such as regular charging and storing in a cool and dry place, can help extend the battery's lifespan and prevent excessive discharge. If you anticipate extended periods of inactivity for your motorcycle in the future, consider using a battery tender or trickle charger to maintain the battery's charge during storage.
If you're uncertain about the condition of your battery or need further assistance, it's recommended to consult a professional or visit a reputable service center to ensure proper diagnosis and resolution of the battery-related issue.
