Yuasa motorcycle technology has been developed and improved over time to fulfil the increasing demands of both bike manufacturers and consumers. Always check with the manufacturer to ensure your charger has a maintenance made and is safe for unattended charging. By connecting an intelligent charger for extended storage periods, you will not only ensure that the battery remains at optimum voltage but also allow security systems and ECU memories to remain active. With the advent of intelligent chargers, riders can now safely monitor and maintain their battery whilst it is still on the bike. Unfortunately this will not stop the natural self-discharge process, which will result in voltage losses and battery damage over time. To combat this, some riders may choose to remove the battery. Typically, at 10☌ the battery loses around 0.1 volts each month rising to approximately 0.4 volts per month at 30° C.Īs well as natural self-discharge, the battery may also have to support electrical loads such as security systems immobilisers and ECU memories. The warmer the environment, the faster the battery will discharge. Even when removed from the bike, the battery is self-discharging at a rate dependent on battery temperature. In most cases the non-start situation is automatically blamed on the battery, however, simple monitoring and maintenance during storage will prevent the majority of these problems.Ī lead acid battery is a live product once commissioned and is constantly releasing electrical energy. It is not uncommon for riders to experience issues when trying to start for the first time after an extended period of storage. – System Support – Supporting security systems and ECU memories whilst the ignition is switched off Issues causing non-startĪ motorcycle is generally used as a seasonal vehicle and may remain unused for long periods of time. – Charging – Operating as a voltage stabiliser to absorb fluctuations in the electrical systems. – Ignition – Supplying power to the ignition system during engine cranking. – Lighting – Delivering steady power before engine start. – Starting – Supplying power when cranking the engine. On a typical bike, the battery has five basic power supply functions: If any of these components are not performing to specification your bike will not start. The triangle of power consists of the starter motor, alternator and the battery itself. The motorcycle battery is a crucial component of what we call the bike’s triangle of power. This guide to all things motorcycle battery should provide you with some useful hints and tips to help keep your battery in the best possible shape and your bike on the road. At some point in our lives most of us have gone to start our motorbike only to find that it’s completely dead. We all know the feeling battery failure can cause.
