Direct replacement for Game Boy Advance SP

The Estry lithium cell matches the original 3.7V 850mAh specification for AGS-001 and AGS-101 models. It fits the SAM-SPRBP(A), AGS-A-BP-USA and BAT-GBASP-1LI part numbers without modification. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. This single pack restores portable play time for handheld owners.

850mAh capacity for typical handheld sessions

At 3.15Wh the cell delivers several hours of gameplay on a full charge, matching the factory runtime of the original pack. Capacity drops off when the console draws peak current during bright backlight use or flash-cart operation. It will not suit users who need extended marathon sessions without recharging. The 1-pack format means no spare is included for swap-out play.

Compact 56.07 x 31.17 x 6.21mm cell runs cool

The 47.5g lithium pack generates minimal heat during normal charge and discharge cycles. No active cooling is required and operation stays silent in the handheld cavity. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards for safe daily use. The slim 6.21mm profile ensures the battery door closes flush on all compatible models.

Questions about this item

Will the 850mAh 3.7V lithium pack fit and charge correctly in my original AGS-101 console?

The pack is built to the exact dimensions 56.07 x 31.17 x 6.21 mm and 3.7 V specification listed for the AGS-101, so it seats in the original compartment and uses the console's stock charging circuit.

How can I verify the 850mAh capacity is performing as expected after installation?

A full charge should deliver roughly 3.15 Wh; if the SP runs for the same play time as a fresh original pack and the voltage settles near 3.7 V under load, the cell is working to spec.

Does the single 1-pack include any tools or adhesive strips, or must I source them separately?

Only the 47.5 g lithium cell is supplied; opening tri-wing screws and any replacement adhesive are not included and must be obtained separately.
