Before you Begin - Battery Terminal Types

There are two terminal connection possibilities that can come with a 12V, 5AH, rechargeable sealed lead-acid battery when purchased from a third-party retailer: F1 and F2.

    • The ION Audio Portable Audio products require the F2-type battery terminals, which are slightly larger than the F1-type terminals.
    • If you purchase a battery with the slimmer F1-type battery connection terminals, it may still be able to be used.  As long as all the other specs of the battery are correct, you may be able to locate "F1 to F2 Step Up Adapters" at a third party retailer. These adapters slip over the slimmer F1 terminals and make them slightly wider, allowing for F2-type terminal connection cables to attach correctly. See the pictures below for a visual representation of the above information:

Be sure to watch the video walkthrough at the top of this article for a full demonstration.

  1. IMPORTANT: First, disconnect all power cables, audio cables, and accessories.  Make sure that the product is completely disconnected from any electrical power outlets.
  2. Next, locate the battery access panel on the side or bottom of the product.  It is secured by four Phillips-head screws.

  4. Next, slide the battery out to reveal the connection wires.Step2b    Step2c

    IMPORTANT: Note how the terminals on the battery are connected.  The red connector is connected to the red positive terminal.  The other connector (blue or black) is connected to the black negative terminal.  The replacement battery must be connected the same way.  Failure to connect to the correct terminals could result in damage to your product.

    * Only use an approved replacement battery which meets the specifications provided by ION Audio.  For more specifics or further information, contact ION Audio Technical Support.

  5. Slide the metal connectors off each of the terminals to disconnect the battery.  Remove the battery from the product.Step3
  6. Connect and insert the new battery, close the side panel, and replace the screws.  You have now completed the process.  Enjoy!

IMPORTANT: The red connector must be connected to the red positive terminal on the battery.  The other connector (blue or black) is connected to the black negative terminal.  Failure to connect to the correct terminals could result in damage to your product.


How to Maximize Battery Lifespan

Rechargeable lead-acid batteries are the same type used in automobiles.  As with your car battery, how you use this battery has a significant impact on its lifespan.  For example, if you forget to turn off your car's lights and drain the battery, a jump start may work a few times.  But after a few full discharges, even a jump won't help, and the battery will need to be replaced.  With proper use and treatment, a lead-acid battery can last for years. 

Here are some recommendations for getting the longest life from the internal battery:

General Usage
      • Fully charge the battery before using it and after every use
      • For maximum life, drain the battery 80% once a month.
      • Avoid completely draining the battery.
      • Avoid storing in high temperatures and moist places.
      • For long-term storage, periodically recharge the battery. If you do not charge the battery for six months, it may not charge again.
      • Bring the battery to a recycling center or dispose of in accordance with local ordinances.
