Checking and Charging Motorcycle Batteries
Understanding Motorcycle Battery Ratings
Motorcycle batteries are rated based on their amp/hour (AH) capacity. For example, a 12AH battery can deliver one amp of current for 12 hours or two amps for six hours. To estimate how long a fully charged motorcycle battery can last with the lights on, divide the power in watts by the voltage to get the current draw in amps. For instance, if you have a 72-watt headlight and tail light running on a 12-volt system, it draws 6 amps. Therefore, a 12AH battery would be depleted in about 2 hours.
Checking Your Motorcycle Battery
To check your new motorcycle battery, follow the manufacturer’s recommended procedure:
1. For Non-Maintenance-Free Batteries: Unwrap the battery, unkink the vent tube, and trim about half an inch off the end. Fill the battery with electrolyte up to the midpoint between the high and low level markings. Let it sit for 1-2 hours. At this stage, the battery will be only 65% charged. Add more electrolyte if needed.
2. Charging:
- Refillable Lead-Antimony Batteries: Charge at one-third of the rated amp/hour capacity for 4-5 hours to reach full charge.
- Maintenance-Free Batteries: Use a constant-current charger capable of up to 16.9 volts, monitoring closely to avoid overcharging.
3. Post-Charging Check: Recheck the electrolyte levels and add water if required. Allow the battery to cool before fitting it into its holder. Ensure any breather tube is routed correctly as per the factory setup.
Tips for Charging Your Battery
1. Polarities Matter: Red is positive, and black is negative. Correct polarity prevents short-circuits and electrical shocks.
2. Charger Compatibility: Ensure the charger output is slightly higher than the battery voltage, but not excessively so.
3. Connection and Levels: Keep connections clean, and maintain electrolyte at the upper level, but not overflowing.
4. Using an Optimizer: Consider using a battery optimizer, which automatically disconnects when the battery is fully charged to prevent overheating.
5. Regular Charging: Charge the battery every 2-3 weeks to maintain optimal performance.
6. Electrolyte Levels: In batteries with distinct upper and lower level markings, ensure the electrolyte remains at the upper level, without exceeding it.
7. Distilled Water Only: Use only distilled water for topping up low cells.
8. Initial Charge: A new battery should be charged for at least 8 hours initially.
9. Dry Batteries: If you have a dry battery, fill the cells slowly and allow it to stand for about 30 minutes before use.
By following these guidelines, you can ensure the longevity and reliability of your motorcycle battery.
