Cycleafer battery and performance


Understand Cycleafer Products performance and its relation to your battery.

Your Cycleafer Bicycle light is designed to deliver an experience that is simple and easy to use. This is only possible through a combination of advanced technologies and sophisticated engineering.

One important technology area is battery and performance. Batteries are a complex technology, and a number of variables contribute to battery performance and related your Cycleafer product performance.

All rechargeable batteries are consumables and have a limited lifespan – eventually their capacity and performance decline so that they need to be replaced. Battery aging can contribute to changes in your Cycleafer product performance. We created this information for those who would like to learn more.

         About lithium-ion batteries

Your Cycleafer product batteries use lithium-ion technology. Compared with older generations of battery technology, lithium-ion batteries charge faster, last longer and have a higher power density, giving more battery life in a lighter package. Rechargeable lithium-ion technology currently provides the best technology for your device. Learn more about lithium-ion batteries.


    How to maximise battery performance

'Battery life' is the amount of time a device runs before it needs to be recharged. 'Battery lifespan' is the amount of time a battery lasts until it needs to be replaced. One factor affecting battery life and lifespan is the mix of things you do with your device. No matter how you use it, there are ways to help. A battery’s lifespan is related to its 'chemical age', which is more than just the passage of time. It includes different factors, such as the number of charge cycles and how it was cared for. Follow these tips to maximise battery performance and help extend battery lifespan. For example, keep your Cycleafer product half-charged when it’s stored for the long term. Also avoid charging or leaving your Cycleafer product in hot environments, including direct sun exposure, for extended periods of time.


       When batteries chemically age

All rechargeable batteries are consumable components that become less effective as they chemically age. 

As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged. This can be referred to as the battery’s maximum capacity – the measure of battery capacity relative to when it was new. In addition, a battery’s ability to deliver maximum instantaneous performance, or 'peak power', may decrease. In order for a phone to function properly, the electronics must be able to draw upon instantaneous power from the battery.

One attribute that affects this instantaneous power delivery is the battery’s impedance. A battery with high impedance may be unable to provide sufficient power to the system that needs it. A battery's impedance can increase if a battery has a higher chemical age. A battery’s impedance will temporarily increase at a low state of charge and in a cold temperature environment. When coupled with a higher chemical age, the impedance increase will be more significant. These are characteristics of battery chemistry that are common to all lithium-ion batteries in the industry.

When power is pulled from a battery with a higher level of impedance, the battery’s voltage will drop to a greater degree. Electronic components require a minimum voltage to properly operate. This includes the device’s internal storage, power circuits and the battery itself. The power management system determines the capability of the battery to supply this power, and manages the loads in order to maintain operations. When the operations can no longer be supported with the full capabilities of the power management system, the system will perform a shutdown to preserve these electronic components. While this shutdown is intentional from the device perspective, it may be unexpected by the user.


                Preventing unexpected shutdowns

With a low battery state of charge, a higher chemical age or colder temperatures, users are more likely to experience unexpected shutdowns. In extreme cases, shutdowns can occur more frequently, thereby rendering the device unreliable or unusable. For all your Cycleafer products dynamically manages performance peaks to prevent the device from unexpectedly shutting down so that your Cycleafer product can still be used. This performance management feature is specific to your Cycleafer product and does not apply to any other products.

The effects of performance management on these newer models may be less noticeable due to their more advanced hardware design.

This performance management works by looking at a combination of the device temperature, battery state of charge and battery impedance. Only if these variables require it, will dynamically manage the maximum performance of some system components, in order to prevent unexpected shutdowns. As a result, the device workloads will self-balance, allowing a smoother distribution of system tasks, rather than larger, quick spikes of performance all at once. In some cases, a user may not notice any differences in daily device performance. The level of perceived change depends on how much performance management is required for a particular device.

In cases that require more extreme forms of this performance management, the user may notice effects such as:

  • Longer High mode use times

  • Lower frame rates while flashing

  • Continues Low Charge 

  • Weather condition ( cold - Hot )

  • During the most extreme cases, the flash will be disabled as visible refreshing in the background may require reloading upon launch
