  • Battery packs ship with the switch set to OFF. Please remember to turn the battery pack ON before powering on your console.
  • Our battery packs are produced in-house, meaning some production time is always involved. Each battery goes through a rigorous quality assurance process before shipping. Even if you don't order a trimmed battery door, please be advised that there may be up to 2 weeks lead time on this product.
  • Parts of the console's battery compartment need to be trimmed in order for the battery pack to fit into the shell. We strongly recommend purchasing an aftermarket Game Boy Advance shell to avoid damaging your genuine shell.
  • These battery packs have been made with aftermarket shells in mind.
  • Battery cover does not need to be trimmed if you prefer to keep the console's original aesthetic, but this option requires removing the battery cover whenever you want to charge the battery pack. 
  • The 1000 mAh version has been discontinued in favor of our Ultimate 1400 mAh model
  • Product images are from our second prototype. The product you receive may vary slightly from what's depicted on the product page with respect to color, dimensions, and LED positioning
  • For customers living in the United States, due to restrictions imposed by USPS, this product can only be shipped to you via ground transportation, which may extend the time it takes for you to receive your order 


  • This product is fragile and should be handled with care. It uses a 1400 mAh rechargeable Lithium ion polymer (LiPo) battery and, as with all LiPo batteries, it can leak or explode if not handled properly. By purchasing this battery pack, you acknowledge that you take responsibility for how you treat this product.
  • Do not force the battery to fit in the Game Boy Advance battery compartment. Trim more plastic away from your shell until you guarantee a good fit.
  • Do not leave your battery pack unattended if it's close to a heat source
  • We recommend not removing and reinserting the battery pack more than you have to. Once you have installed it in your system, leave it there and charge it either by removing the battery door or by trimming the battery door to fit the charger
