Upgraded Gameboy Advance SP Battery

Battery great. No issues so far. Perfect fit and it’s been a few months.

Works great. It was a perfect fit no issues

It's a good battery, but the original 600mah Gameboy Advance SP states that it will last anywhere from 7 to 10 hours with the backlight turned on and about 18 hours with it off. This was tested on the Gameboy Advance SP 001 version/model, which is not the brighter version/model which is the 101 model. With that being said this 2800mah battery right out of the box gave me a good 1 hour and 36 minutes before the red light to charge came on. It then took 1 hour and 53 minutes to get to a full charge. I then tested to see how long it would run. I tested Pokemon Ruby with sound and backlight on the whole time. This 2800mah battery was able to give me a total of 10 hours and 5 minutes of play time. It's a good amount of time that it was able to produced, but it doesn't sound any better than what the original 600mah was said to produce. It's a good product but to say it's a big improvement or upgrade is a no. The installation was easy as the original and fits right in. If your old battery doesn't last more than 2-3 hours or just dead, yes you should definitely buy this replacement! Attached are the times that I screenshotted as I was testing the duration of each phase.

Cheapest way to fix an old device, started right up

I was surprised with how quick it charges and how long it lasts. I played for a good 10 hours or more until it gave me the red light. I also always use the backlight, but it can last longer if you keep the backlight off while playing in well lit rooms. For heavy gaming, 2 are well worth it.

Edit: after a good while and playing Boktai 2, Golden Sun 2 and even LoZ:OoS/A, this battery does last a good while long than the original, even after it's fully charged! Even if you haven't used it for a few days, it still holds up! Just be sure to charge it after wks or a month of not using it. OG: If you own an sp since it came out, want to buy one, or recently bought one second hand, this is a great upgrade for your SP. Especially if you've upgraded to a better quality screen like I've done. The battery life am testing right now after I drained it and fully charged it. I do know is that it stopped charging once the battery became fully charged. The battery itself is similar in dimension to the original battery.

This battery has worked well on my gameboys. I would recommend it to anyone looking to extend their battery life. I will say you do have to charge and discharge the battery fully to work right it was by about the 4,5th charge that the battery life was optimal.

Everything I needed in one box to replace the battery. It was extremely simple and straightforward thanks to the included screwdriver. This battery has a significantly larger capacity than the original and is a perfect upgrade. Moreover, the battery fit within the housing perfectly, and I have had no issues thus far.
