Motorcycle Battery Technical Guide
Bike batteries are available in a wide variety and each battery has its own internal characteristics. When buying a bike battery, what you should look for in a battery is its ability to store charge, the notion of storing charge refers to the battery capacity. Having a battery with high DOD (Depth of Discharge) that you should look for in a battery is one crucial factor. Depth of discharge is defined as the fraction or percentage of a fully charged battery that has been discharged. If the battery has a 10Ah capacity and its depth of discharge is 9Ah, it can be said that the useful capacity of the battery is 90%.
Traditionally, batteries were designed with low DOD which made them vulnerable to premature failure. Having low DOD means the battery would require a frequent charge. As the charging and discharging cycle increases, the battery loses its useful lifecycle. Selecting the right size and type of battery doesn’t only give you a good ride, but it also perfectly powers your bike accessory. Although, bike batteries have become advanced in terms of design and capacity. Most of the battery manufacturers are still struggling with emerging issues of the battery due to material properties. A good battery has low internal resistance and it plays a substantial role in determining battery life cycle and stator life.
Having a battery with high internal resistance can be harmful to the bike and the stator that charges it. Resistance is the property of the material to oppose the flow of current. Some of the battery cells and terminals are made of poor quality or counterfeit material. As a result, batteries offer higher resistance and hinder the smooth flow of current. Therefore, a bit of technical knowledge about battery could save your time, money, and ultimately the bike.
