Direct GBA SP replacement

The Estry AGS-001 is a new lithium battery built to match the original specifications for the AGS-001, GBA SP and Advance SP handhelds. It delivers 3.7V and 900mAh capacity in a single pack, giving owners a straightforward way to restore playtime without modifying the console.

Fits the original battery bay

The cell measures 55.16 x 31.71 x 5.44mm and weighs 43.3g, so it slots straight into the existing compartment and connects to the stock connector. No soldering or case trimming is required, leaving the console’s shell and latch mechanism untouched.

3.33Wh rated for typical sessions

At 3.33Wh the pack comfortably powers several hours of gameplay on a full charge, while integrated protection guards against overcharge, over-discharge, over-voltage and short circuits. Heavy backlight use or extended sleep periods will drain the cell faster, so frequent players may want a spare charged unit.

Questions about this item

How long will the 900mAh capacity keep a GBA SP running under sustained play?

The 900mAh cell stores 3.33Wh at 3.7V; actual run-time depends on screen brightness and volume but matches the original factory specification.

Does the pack heat up or draw extra power after hours of continuous use?

Built-in overcharge, over-discharge, over-voltage and short-circuit protection limits heat and parasitic drain during extended sessions.

What must I already own to install this battery?

A compatible AGS-001, GBA SP or Advance SP console and a small tri-wing or Phillips screwdriver to open the battery compartment.
