Review: Volver a encender mi Game Boy de la infancia 💚 - 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. ## Features - Never run out of power while you are about to upgrade the winning point - Money-saving and environment-protective by using the rechargeable battery - Voltage: 3.7V，Capacity: 850mAh，Type: rechargeable lithium ion polymer - Compatible with:Nintendo Gameboy Advance SP / GBA SP ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FJ2WOJE | | Antenna Location | Gaming Console | | Battery Capacity | 850 Milliamp Hours | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Brand | OSTENT | | Brand Name | OSTENT | | Compatible Phone Models | Nintendo GBA SP | | Customer Reviews | 4.4 out of 5 stars 753 Reviews | | External Testing Certification | Não Aplicável | | Item Dimensions | 5.2 x 3.1 x 0.5 Centimeters | | Item Weight Unit of Measure | 0.02 Kilograms | | Manufacturer | OSTENT | | Model Number | 024400 | | Net Quantity | 1 Count | | Number of Batteries | 1 Lithium Ion batteries required. | | Recommended Uses For Product | Gaming Console | | 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 - **Item Weight:** 0.02 Kilograms - **Item dimensions L x W x H:** 5.2 x 3.1 x 0.5 Centimeters - **Net Quantity:** 1 Count - **Number of Batteries:** 1 Lithium Ion batteries required. - **Recommended Uses For Product:** Gaming Console - **Reusability:** Rechargeable - **Voltage:** 3.7 Volts ## Images ![OSTENT 850mAh Lithium Ion Li-ion Polymer Rechargeable Battery Pack Tool Kit for Nintendo Gameboy Advance SP GBA SP - Image 1](https://m.media-amazon.com/images/I/71sGsTYM2UL.jpg) ![OSTENT 850mAh Lithium Ion Li-ion Polymer Rechargeable Battery Pack Tool Kit for Nintendo Gameboy Advance SP GBA SP - Image 2](https://m.media-amazon.com/images/I/71lqQn60zQL.jpg) ![OSTENT 850mAh Lithium Ion Li-ion Polymer Rechargeable Battery Pack Tool Kit for Nintendo Gameboy Advance SP GBA SP - Image 3](https://m.media-amazon.com/images/I/715nHRgF-VL.jpg) ![OSTENT 850mAh Lithium Ion Li-ion Polymer Rechargeable Battery Pack Tool Kit for Nintendo Gameboy Advance SP GBA SP - Image 4](https://m.media-amazon.com/images/I/71fj5EwjwWL.jpg) ![OSTENT 850mAh Lithium Ion Li-ion Polymer Rechargeable Battery Pack Tool Kit for Nintendo Gameboy Advance SP GBA SP - Image 5](https://m.media-amazon.com/images/I/71noZoIRq2L.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 ### ⭐⭐⭐⭐⭐ Battery for GBA SP *by A***J on 24 May 2019* Amaing. ### ⭐⭐⭐⭐⭐ Volver a encender mi Game Boy de la infancia 💚 *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.

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. ## Frequently Bought Together - OSTENT 850mAh Rechargeable Lithium-ion Battery + Tool Pack Kit for Nintendo GBA SP Game Boy Advance SP - Charger for Gameboy Advance SP, AC Adapter for Nintendo NDS and Game Boy Advance SP Systems, Wall Travel Charger Power Cord Charging Cable 5.2V 450mA for GBA SP - Xahpower Charger for Gameboy Advance sp, GBA SP Charger Cable Cord for Nintendo DS Original Console(NDS)/Game Boy Advance SP --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/137994523-ostent-850mah-lithium-ion-li-ion-polymer-rechargeable-battery-pack](https://www.desertcart.com.kw/products/137994523-ostent-850mah-lithium-ion-li-ion-polymer-rechargeable-battery-pack) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-19*
