Direct replacement for Advance SP

This lithium-ion cell is built to fit the Advance SP AGS-001 and GBA SP consoles. It delivers 900 mAh at 3.7 V and matches the original dimensions of 55.16 x 31.71 x 5.44 mm. The pack weighs 18.3 g and carries ISO9001, RoHS and CE certification.

Built-in protection and decoded chip

A fully decoded chip communicates with the console exactly like the factory unit. Over-charge, over-discharge, over-voltage and short-circuit safeguards are integrated. The battery ships in shock-absorbing foam to prevent transit damage.

Restores original run-time for aging handhelds

Owners of an Advance SP or GBA SP whose factory cell no longer holds a charge will regain stock capacity. The upgrade is worthwhile when the existing battery shows reduced play time or swelling. Buyers needing higher capacity than 900 mAh or a different form factor should look elsewhere.

Questions about this item

What voltage does the 3.7 V lithium-ion cell deliver to the Advance SP AGS-001?

The cell is rated at 3.7 V and 900 mAh, matching the original AGS-003 specification for the Advance SP and GBA SP consoles.

Will the 55.16 x 31.71 x 5.44 mm pack fit the original battery compartment without modification?

Yes, those dimensions and the 18.3 g weight replicate the OEM AGS-003 form factor, so it seats in the stock bay and the cover closes normally.

Which step do installers most often miss when fitting the decoded chip connector?

Align the keyed plug fully before snapping the shell shut; a partially seated connector causes the console to refuse power-up.
