Edge 540 Solar and 840 Solar Battery Life Assumptions
The battery life of your Edge device may be impacted by the usage of features within the product or the way it is used. The information in the tables below is presented to help outline the conditions used to determine the estimated battery life specification. The additional usage of these features or other features not included below may result in reduced battery life. The information presented below is presented as a general guide for reference only on the Edge 540 and Edge 840 products.

1 Battery Saver Backlight - The backlight brightness and timeout settings do not automatically change when Battery Saver is enabled. Users may change the backlight brightness after enabling Battery Saver by selecting Reduce Backlight in the Battery Saver menu. Users may change the backlight timeout through System->Display. Leaving the brightness set to Auto and timeout set to Stays On may result in a reduction in battery life.
2 Following a Course - Each course is unique regarding the number and type of alerts generated. The number of alerts generated by the course will impact battery life. Courses that generate a large number or frequent alerts will consume more battery life than courses with fewer turns or alerts
3 This calculation assumes that daytime riding is done in consistent 75,000 lux conditions. To extend battery life further, see “Tips for Using the Edge 540/840 Solar Device” in the Owner’s Manual. The Solar harvester will always be enabled in the specified temperature range. However, when the battery is at or near 100% the harvester may reduce its power output which may reduce the overall improvement in battery life.
