Battery for Gameboy Advance SP(GBA SP), Upgraded 1600mAh super high capacity Li-Ion replacement battery with high capacity for Nintendo AGS-001, AGS-003, AGS-101

Works as expected, easy installation and bought my Gameboy SP back to life.

Can't say anything about the battery life but at least it fits, which is more than I can say about other vendors I've tried.

Lasts super long time

Works well. Very pleased to be able to bring an old gameboy back to life.

I have had my Game Boy more than 15years and it's passed from one generation to another. It still works and the battery is ok. However, this new battery has a much bigger battery capacity so last longer which is great for days out, when travelling on the train and all those other times when you sat around twiddling your thumbs, such as airports, plane trips, A&E and more.Was easy to install and works a treat. Don't know how durable it is but so far so good. Reasonable price at currently £12.68

After having a few poor experiences - I'm always sceptical these days about battery life claims. I'm happy to report that this GBA-SP battery from HUAENG actually lives up to its claims.My original GBA-SP's battery is getting on for 20 years old at this point yet it still holds a charge quite well. They don't build them like they used to! This ancient 600mAh battery gets around 5 hours on my test.My test involved leaving a game running on it's menu screen with the volume half way up. This menu has animation so it is actually 'working' the GBA-SP at the time. This 1600mAh battery got just over 13 hours!Battery replacement is a single screw on the bottom of the GBA-SP (ah - the good old days!). This package includes a small screwdriver that just about does the job.While I can't vouch for how many cycles this battery will last I can very much recommend it at this stage.

Battery lasts 4 hours at best on a Nintendo sp with ips screen on low brightness and very low sound.
