SuperSmashMedia® - 850mAh Replacement Battery Pack Kit for Gameboy Advance SP Screwdriver Included (Game Boy Advance GBA SP)

This replacement battery pack has an extra 250mAh capacity compared to the original Nintendo GBA battery and it really shows. A full charge last so much longer than before. Even when the GBA's red light comes on indicting that the battery is running low I've found that it still has about two hours of use left. I'd recommend following the simple calibration guidance on the first and second charge for optimal performance.

This little chappie brought new life to my Nintendo Gameboy Advance SP which I bought when it was first launched in the UK back in the day. The instructions are really simple to follow and it even comes with a little screwdriver thus making the whole process stupendously simple After installing this new battery (which, incidentally, is VERY easy to do) I was able to give the console away to someone for their 12 year old son's birthday. I totally recommend this product.

Good replacement GBA SP battery which is easy to install, and offers decent battery life. Easy to recommend.

Our Gameboy Advance had been languishing in a drawer for the past few years. When I took it out tried to charge it but all that happened was the orange light came on for a second and went out again. Googled the issue and it pointed to the battery being exhausted. Ordered this one on Prime and removed the panel with the supplied screwdriver. Popped in the new battery, Hey Presto! up and running again. Just remember to charge the battery fully before using and exhaust the battery fully after the first charging cycle to maximise longevity.

I bought this for my Gameboy Advance SP to play older Pokemon games that rely on clock-based events. I followed the instructions to the letter, and it worked. The error message no longer came up to say that the internal battery had run dry. I had not used the Gameboy much since then, but when I tried to use it today, the same internal battery error message came up with the new battery. Very disappointed

Just as the title says, I purchased this as a replacement battery for my Gameboy Advance and it has been working great now for several months. Would recommend.

It's certainly not 850mAh. Purchased it to replace a previously bulging original OEM battery and it lasts far less time than my original. I'd recommend going elsewhere for an SP battery.

Even though it took a week longer than it said it would it's awesome my game boy advance has new life again haha 🎮
