Why Is It Important to Replace the Battery in Your Garmin Forerunner 935?
Replacing the battery in your Garmin Forerunner 935 is important for maintaining its functionality and performance. A worn-out battery can lead to shorter device usage, inaccurate data recording, and ultimately, a diminished running experience.
According to Garmin, a leader in GPS technology and fitness wearables, batteries in devices degrade over time and usage. As batteries age, their ability to hold a charge diminishes, affecting the device’s overall performance.
The underlying reasons for replacing the battery include reduced battery life and power retention. Lithium-ion batteries, used in Garmin devices, undergo chemical reactions during charging that can create wear over time. When a battery is constantly drained to below a critical level, it loses capacity. Furthermore, environmental conditions such as temperature fluctuations can exacerbate battery wear.
Battery degradation follows a predictable pattern. As the battery cycles (charging and discharging) increase, the electrodes in the battery become less efficient. Additionally, battery age affects performance; most lithium-ion batteries last around 300 to 500 charge cycles before significant capacity loss occurs.
Specific conditions, like extended exposure to high temperatures or humidity, can contribute to premature battery failure. For instance, leaving the Forerunner 935 in a hot car can increase the likelihood of battery damage. Similarly, regularly allowing the battery to drain completely before recharging can shorten its lifespan.
In conclusion, regularly replacing your Garmin Forerunner 935 battery ensures optimal performance and longevity of the device. This practice can enhance your overall experience and ensure accurate tracking during your activities.
