Game Boy Advance SP Replacement Battery Pack for GBA SP (packaging may vary)

A couple of years ago my blue GBA SP stopped charging its battery. No matter how many times I tried, my battery simply wouldn't charge. So, I was forced to use my brother's red GBA SP (which he had long since stopped playing) and eventually I stopped playing my GBA games.I recently got back into Pokemon again, and I was tired of playing on my bro's red GBA SP, so I looked on Amazon for replacement batteries. At the time, this was the cheapest one. Also, as another reviewer mentioned, it comes with a Phillips-head screwdriver, so that you can get the back case open. Anyway, I ordered the battery on the 18th, and it came in today.I didn't charge the battery, but it worked for a little while until the battery went red. So, I tried charging it, but the charging light didn't come on. Curious, I decided to run a couple of tests.First, I opened up my bro's GBA SP and charged the battery in that. Charging light came on, it worked fine.Then, I decided to try charging the other battery (the one I had thought went bad) and charged it for 5-10 minutes. I unplugged the GBA and turned it on; it worked fine (but was still low on power.)So, why do I mention this? If your battery doesn't charge, chances are the problem isn't with the battery; it's with the GBA SP. I think what happened to mine is that for some reason the charging mechanism in it doesn't work anymore; I don't know how or why, I don't have much technical knowledge with the GBA SP, but to me that seems to be the problem.Never fear, however; if you have another GBA SP, you can use that to charge the original battery, and when it's done you can place it back in your GBA SP. If you don't have one, then I'm sorry, but you probably will need a new GBA SP.Anyway, should you get this battery? Absolutely; it's a great battery and it works. I'll edit this review in 2 or so weeks about the durability of this battery, but right now everything works great. As I mentioned earlier, it comes with a small screwdriver that will open the back case, so all in all it's a good deal.-ScottP.S. The actual battery looks different then the one displayed here; I'll try to get a picture of it up on here. Also, apparently the company gives a portion of the money earned from selling this product to the Kids in Need foundation, which gives free school supplies to kids in need.

Needed to replace the battery in my Gameboy bc it was starting to bulge,, this battery was easy to put in and it works fine.

Even came with a screw driver!

Dug out my old Game Advance SP from storage, was excited to plug it in and found the battery to be horribly bloated (like, pressing out on the back cover!). Ordered this as a replacement, came fast, fit perfect, ready to go!

Giving 4/5 due to first one received being a dead battery. Not a lot you can do to test that ahead of time but guessing these have some age on them.Second one works great and I have allowed it to fully charge and drain about 4 times now with an average life of about 4hrs and 3min and 1hr and 20min to fully recharge again. Happy to have a fresh battery for my GBA SP!

Great price and super easy install. I used my own screwdriver but it's nice that it comes with one.

Perfect fit inside gameboy advanced sp. Noticed longer game sessions than my original battery. Highly recommended!

I was prepping a GBA for sale. The battery would no longer take a charge, so I ordered this one on Amazon.Fit and worked like an OEM battery, perfect!No complaints, highly recommended!
