How to Pick the Best Charger for Motorcycle

If you have vehicles or toys that are powered by 6 volt or 12 volt batteries then you need to have a battery charger to help you maintain a full charge on your batteries. Before you go shopping for a battery charger, consider the following items so you can choose a charger that is right for your needs.

Type of Battery you have

There are several different types of batteries on the market. You want to make sure that the charger you are buying is compatible with the battery type that you own.


You need to know the voltage of the batteries that you will charge the most. The battery voltage should be listed clearly on the side of the battery. If you have both 6 volt and 12 volt batteries then choose a charger that is capable of charging both voltages.

Modes of Charge

A battery charger can provide your battery with enough power to bring your motorcycle to life instantly, or it can be connected to your battery to provide a float charge. The float charge mode will be used when the motorcycle is being stored and not used for an extended amount of time. The charger will be able to sense when the battery discharges to a certain level and will then power on automatically and boost the power of the battery.

Safety Features

There has been a lot of improvement in safety feature designs for batteries. At one time you could blow a battery up if you connected the positive charging lead to the negative battery terminal. Today with the reverse polarity technology in place you are not going to be able to damage a battery in this manner. The charger will into provide any current if the battery is connected improperly.

At one time you could cause a fire if the negative lead and the positive lead of a battery charger were to make contact while the unit was plugged in. The no spark technology has eradicated that possibility and even if the leads touch you will not be in danger of a spark or a fire.

Connection Possibilities

The majority of battery chargers come with alligator clamps on the end of leads that connect the positive and negative battery terminals to the appropriate power leads on the charger. If you are going to use the charger to maintain a battery then you will want ring connectors instead of alligator clamps. The ring connectors fasten securely and will not be easily disconnected.

Final Note

A battery charger used to be a simple way to help a discharged battery provide cranking power to the item it was connected to. The battery chargers of today are designed to provide those quick cranking charges, and then maintain the level of power in a battery when the battery is not in use. The new maintenance technology means that your battery is hot and ready when you need it.

The battery chargers can now also reverse damages that have been done to a battery, and they can help eliminate sulfur build-up so the battery retains proper health longer, and your battery lasts longer. Battery chargers are not a luxury. They are now a necessity to help protect your investment.
