A quality product by OSTENT. Review: Compré esta batería para mi Game Boy Advance, que llevaba años guardada en un cajón sin encenderse desde que era pequeña. No sabía si iba a funcionar o si la consola ya estaría estropeada, pero al ponerle esta batería... ¡ha vuelto a la vida! No puedo explicar la sensación de verla encenderse otra vez. Fue como volver directamente a mi infancia. La batería llegó con las herramientas necesarias, así que el cambio fue muy sencillo y rápido. Se ajusta perfectamente, carga bien y la consola funciona sin problemas. La duración está muy bien para lo que es, y lo importante es que permite usar la consola como antes, sin complicaciones. Me ha hecho mucha ilusión poder volver a jugar a mis juegos de niña. Es un producto sencillo, pero tiene detrás un valor sentimental enorme si tienes una consola guardada y quieres revivirla. Si te pasa como a mí, y tienes tu GBA esperando desde hace años, de verdad, esta batería es una manera preciosa de devolverle vida. Review: De batterij hield het maar 1 uur en 45 minuten van volgeladen naar uitvallen. Tevens is de batterij ietsjes korter tov het orginele waardoor deze niet goed past in de gameboy advance sp en af en toe uitvalt ivm contactverlies echter met wat elektrical tape heb ik dit verholpen. ## Features - Rechargeable Lithium, 100% brand-new and high quality - 850 mAh 3.7V Rechargeable Battery for GBA SP - Never run out of power while you are about to upgrade the winning point - Money-saving and environment-protective by using the rechargeable battery - Please charge the battery for 12 hours when using for the first time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FJ2WOJE | | Antenna Location | Gaming Console | | Battery Capacity | 850 Milliamp Hours | | Battery Cell Type | Lithium Ion | | Best Sellers Rank | #5,645 in Videogames ( See Top 100 in Videogames ) #6 in Game Boy Advance Accessories | | Brand | OSTENT | | Compatible Phone Models | Nintendo Game Boy | | Customer Reviews | 4.5 4.5 out of 5 stars (2,740) | | External Testing Certification | Não Aplicável | | Item Dimensions | 5.2 x 3.1 x 0.5 centimeters | | Item Weight | 0.02 Kilograms | | Manufacturer | OSTENT | | Model Number | 024400 | | Number of Batteries | 1 Lithium Ion batteries required. | | Reusability | Rechargeable | | UPC | 609652483287 | | Unit Count | 1 Count | | Voltage | 3.7 Volts | ## Product Details - **Battery capacity:** 850 Milliamp Hours - **Battery cell composition:** Lithium Ion - **Brand:** OSTENT - **Number of batteries:** 1 Lithium Ion batteries required. - **Recommended uses for product:** Gaming Console ## Images ![OSTENT 850mAh Rechargeable Lithium-ion Battery + Tool Kit Pack Compatible for Nintendo Game Boy Advanced GBA SP Console - Image 1](https://m.media-amazon.com/images/I/71sGsTYM2UL.jpg) ## Questions & Answers **Q: What are the exact product dimensions? mm are preferred.** A: The dimension of battery is 52x31x5mm . **Q: I plugged battery in and charge light went out do I continue to leave plugged in?** A: If it's fully charged then it's fully charged. Try playing it until it red lights (low battery warning). If the time it takes to red light is way too short, somethings wrong. If the gameplay session lasts as long as it should (or longer), then all is well and the battery must've been shipped mostly charged already. If it didn't charge AND it doesn't turn on, make sure the gba sp battery tabs are clean and sticking out far enough to make proper contact with the battery (known issue with nintendo handhelds from sp forward). If it still doesn't charge AND won't turn on maybe you got a dud. **Q: I am about to do some exhaustive testing of this battery, does anyone doubt the capacity?** A: Not really any doubt. Not sure why the testing. Works fine in my gameboy **Q: Can I return this item?** A: That would be an Amazon policy question, but if brand new they have a fairly liberal policy. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***P on 5 November 2025* Compré esta batería para mi Game Boy Advance, que llevaba años guardada en un cajón sin encenderse desde que era pequeña.
