A33 Wireless Weatherproof Speaker - Play time of the rechargeable battery.
Reference Number: AA-00386 Views: 6831 Last Updated: 2015-06-24 09:42

How long should the battery play on a full charge? 

There are a number of factors that will affect how long the A33 Wireless Speaker will play on a full battery charge. 

Some things to check: 

  • Is the battery fully charged? 
    • The shortest charge time will be with the power adapter attached and the unit turned off .  Playing the unit during charging will take additional time. 
     
  •  
  • How old is the battery? 
    • A new battery will charge faster and reach a higher charge than an older battery.  This is characteristic of all rechargeable batteries. 
     
  •  
  • Is the battery power switch on the right end of the unit in the OFF position when the Wireless Speaker is not in use? 
    •  Leaving the battery power switch ON, even though the Power button on top of the unit is OFF, will gradually discharge the battery. 
     
  •  
  •  What volume level is being used for playing music? 
    • The volume level has a significant effect on the length of the battery charge.
    •  For example, here are some trial results on play time for a new, fully charged battery: 
      • At half volume setting (2 & 1/2 bars on indicator) - 6 to 6.5 hours
      • At full volume setting (5 bars on indicator) - 2.5 hours

The above factors affect the play time and the recharging of the speaker.  Each time the battery is charged and discharged (charge cycles), the battery capacity slightly diminishes.  Rechargeable batteries have a limited number of charge cycles and eventually need to be replaced.  You may wish to replace your battery when, or before, the battery does not supply enough power for acceptable playing time.  Please contact TDK Life on Record Support for assistance.
