SKU CH-KRB8-HGMK2

Rechargeable 3.7V 850mAh lithium-ion pack for GBA SP, includes screwdriver for easy installation

  • 7V 850mAh capacity extends GBA SP playtime
  • Includes mini screwdriver for straightforward battery replacement
  • Compact 53x32 mm size fits original battery compartment
  • Lightweight 31g lithium-ion pack adds minimal bulk
  • Rechargeable Li-ion chemistry supports repeated charge cycles

Replacement Battery for Game Boy Advance SP

This 3.7V 850mAh lithium-ion pack is designed specifically for the Game Boy Advance SP handheld console. It serves as a direct replacement for an exhausted or failing original battery. A mini screwdriver is included in the package to assist with the installation process. The pack weighs 31g and measures approximately 53x32 mm.

Verify Console Model and Battery Compartment Access

Before ordering, confirm that the handheld is a Game Boy Advance SP and not another model in the Game Boy family. Ensure you are comfortable opening the battery compartment using the provided screwdriver. The replacement requires removing the battery cover and disconnecting the old pack, so basic disassembly is necessary. Check that the existing connector matches the replacement unit.

Upgrades an Ageing Original Battery

This pack replaces the factory-fitted battery that no longer holds a useful charge after years of service. The jump is worth it when play time per charge has dropped significantly or the console shuts down unexpectedly. It restores portable runtime without modifying the hardware. Buyers who need a higher capacity than 850mAh or a different voltage should look elsewhere.
