My GBA sp's battery died 5 years ago, and when I got this, it was alive again! My only complaint is that there is no conclusive picture as to what it looks like, but so far, it's been working normally.
Ordered on 5/12/2019. Received pictured product, 600mah batteries. My original Advance SP batteries lasted about 30 minutes. The new ones last for hours! A great way to breath new life in to the best Game Boy made.
So for awhile now the switch on my Gameboy advance sp wasn't working properly...when I would try and turn my Gameboy on, it wouldn't. I would have to carefully toggle the power switch for my Gameboy to turn on. I thought that maybe it was a problem with the battery (the battery wasn't holding a full charge sometimes after charging it) so I decided to order a new battery, hoping it would fix the power problem.
As you can see in the pictures, the battery comes with a tiny little screwdriver so you can unscrew the back which holds the battery. I have a picture of what the difference between the original battery and the new one look like and that the new one does in fact fit perfectly.
Even though the new battery didn't fix the power switch problem (guess my Gameboy advance sp is finally starting to die on me, though it is over 10 years old) the new battery keeps a charge just fine so at least there's that + the little Phillips head screwdriver is a nice little bonus.
This is just like the picture, this battery is a perfect fit for my GBA sp and works perfectly, and it even comes with the screwdriver to remove the battery cover. Just please make sure like every new battery make sure you fully charge it before using
This battery was bought for the sole purpose of bringing my Gameboy SP back to life. At first it did made me worry when the charge light went out so easily, but I decided to continue to let it charge. Upon turning it on once fully charged, my dead Gameboy works just like new. I haven't had the battery for long (a few days), so I cannot attest to how long it will last for. I bought it to make my device work and that is what it did.
This battery worked great. There was no tight or loose fit at all. It fit perfect, just as it was the OEM. Played on a full charge and no problems after 2 hours. I charged it up and it held its charge for 2+ hours after that and still didn't run out.
Used to power my Gameboy Advance Sp which has never had the original battery replaced. Lasts almost 3 hours even on a partial charge so battery life is pretty good (haven't done a confirmed full charge yet). Easy to use, came fast, can't complain!
