3DS XL Battery Pack, 2000mAh Replacement Rechargeable Lithium-ion Battery + Tool Pack Kit Compatible with Nintendo 3DS XL/New 3DS XL

I recently purchased a replacement 2000mAh battery for my New Nintendo 3DS XL, hoping to rejuvenate my gaming experience. Unfortunately, this battery has been a letdown. Despite its claims of a 2000mAh capacity, it struggles to hold a charge, not even lasting a full day on standby. This leads me to suspect that the battery may be old or not up to original specifications. I would not recommend this product to others looking for a reliable power source for their device.

Advertising a screwdriver but none came with it. Battery might have been used before because it was not flat to fit in the handheld.

Thank you
