  • Low Battery Indicator: Many Fitbit scales have a low battery warning. If your scale displays a battery symbol or alert indicating it needs replacement, it’s time to switch it out.

  • Delayed Response: A lag in the scale’s response time when you step on it can also suggest that the battery is running low. If the display takes longer than usual to light up, consider replacing the battery.
