How to Charge Your Motorcycle Battery Before The Riding Season Picks Up

As apposed to a car, the alternator that charges the battery on a motorcycle is not quite strong enough to fully charge your lead-acid battery. Motorcycles batteries tend to run their course faster than those in a car. The stronger alternator in a car will have a much easier time keeping the lead-acid batteries charged and prevent them from getting deeply discharged. Because of the difference between car batteries and motorcycle batteries, one must use a motorcycle-specific battery charger when charging their motorcycle battery as a car battery charger will put out too much charge and possible damage the battery.


When a battery loses it’s charge completely, even when recharged, you run the risk of reducing the calendar life of the battery. Although under ideal conditions, and with proper maintenance, a motorcycle battery should last its full manufacturer life expectancy. Keep in mind though, many factors can play a role in your batteries life such as weather and temperature. If riding in hot desert areas, you may find yourself replacing your battery more than someone who drives the same motorcycle but lives in a fairer climate.


Now the you have an overview of motorcycle battery specifics, these simple steps bellow will show you how easy it is to charge your battery:
