Your motorcycle battery is what provides the electrical power to start your motorcycle engine as well as power all of the lights and electronics on your bike. Over time, your battery will lose its ability to hold a charge and will need to be replaced. When it comes time to purchase a new battery, you will need to know how to charge it properly in order not to damage the battery or your motorcycle.

What You Will Need

To charge your motorcycle battery, you will need:
-A charger specifically designed to charge lead-acid batteries
-An adapter cable that will allow you to plug the charger into a standard household outlet
-Eye protection

It is important to use a charger that is specifically designed to charge lead-acid batteries, as other types of chargers can damage the battery or even cause a fire. Be sure to read the instructions that come with your charger carefully before use.

To charge your motorcycle battery:
1. Park your motorcycle in a well-ventilated area and make sure that it is turned off. Remove the seat and side panels to access the battery.
2. Disconnect the negative (-) terminal of the battery first, using a wrench if necessary. Then disconnect the positive (+) terminal.
3. Clean the terminals with a wire brush to remove any corrosion.
4. Connect the adapter cable to the charger, then plug the charger into a standard household outlet.
5. Connect the positive (+) terminal of the battery to the positive output on the charger, then connect the negative (-) terminal of the battery to the negative output on the charger.
6. Turn on the charger and monitoring charging process closely. If charging rate is too high, unplug immediately and check connections. When charging is complete, unplug charger and disconnect adapter cable from bike before reconnecting battery terminals.

Preparing Your Motorcycle

To get the most out of your motorcycle battery, you should prep it before each ride. This will help to prevent the battery from dying prematurely. You should clean the battery terminals with a wire brush to remove any buildup of corrosion. It’s also a good idea to check the fluid levels in the battery before each ride.

Connecting the Battery Charger

Before connecting the battery charger, check the following:
-The motorcycle is in a well-ventilated area.
-The motorcycle is turned off and the key removed.
-The charging leads are not touching each other or any metal surfaces.

To connect the battery charger:
-Connect the positive (+) lead of the charger to the positive terminal of the battery.
-Connect the negative (-) lead of the charger to a clean, metal surface on the motorcycle that is not connected to the negative terminal of the battery. This will help prevent sparks from occurring when you connect the leads.
-Turn on the charger.

Charging the Battery

If your motorcycle is not starting, it may be because the battery needs to be charged. You can do this by connecting the positive and negative terminals of the battery to a charger. Make sure you read the charging instructions that come with the charger, as well as the safety precautions. Once the battery is charged, you should be able to start your motorcycle.

Disconnecting the Battery Charger

When your motorcycle’s battery is fully charged, disconnect the charger by first removing the “positive” or red clip, then the “negative” or black clip. If your charger has a switch, set it to “off.”
