That is, a battery can show a status of“charged” but maintain a reduced charge capacity (health).Check the Battery ChargeTo check the battery charge, press and release the status button on the batterycharge gauge to illuminate the charge-level lights. Each light representsapproximately 20 percent of the total battery charge. For example, if thebattery has 80 percent of its charge remaining, four of the lights are on.
