How to Replace a Motorcycle Battery
Every motorcycle owner should learn some basic maintenance skills, and replacing a motorcycle battery is both easy and important. Just like any other vehicle, a motorcycle will require a fresh battery from time to time. Removing the battery is also a necessary step in charging it or placing the motorcycle into storage.
First, you must locate the access point for the battery. In most cases, this will be housed under the seat. You can lift the seat up to access the battery case, which will be secured by a strap.
Once the strap is removed, you may disconnect the battery leads. Be sure to remove the negative or black cable first to prevent the chance of sparks or electrical shock. Also remove the sensor if your motorcycle is equipped with one so that it can be cleaned and replaced as necessary.
After removing the battery, inspect it for any signs of damage, such as cracking. Be careful not to touch any leaking battery acid with your bare hands as it is very corrosive. Also be sure to clean the connection points of the battery cables to remove any acid or crystal build-up. This will improve the connection with the new battery. Special pads and gels are available to keep the connection points clean and transmit charge more efficiently.
Gently place the new battery into the casing. Connect the cables in reverse order, first connecting the red or positive cable, then securing the black or negative cable. Replace the strap securely to keep the battery in place. Once the new battery is snugly in place, you may lower the seat and secure it to its proper position.
After replacing a battery, it's a good idea to test the motorcycle to ensure that everything works as it should. Turn on the ignition to check that the lights come on. Next, start the motorcycle. If it starts with no hesitation, the battery change was successful. If there are any problems starting the motorcycle, double-check the battery connection. If that does not work, there may be a mechanical problem with the bike or its electrical systems, or the battery may not be sufficiently charged.
Once your new battery is installed, be sure to dispose of your old battery safely and legally. You may be able to recycle your motorcycle battery through a local battery supply store, recycling center or motorcycle repair shop. In some cases, you may even be paid for the old battery.
