MegaBat800 Game Boy Advance SP High Capacity Battery

Custom made battery for the Game Boy Advance SP with a true and tested capacity of 800mAh for extra hours of play time in comparison to the old and failing OEM batteries and the many clones with less than 600mAh that they claim.

 

The battery does not have the 2 plastic teeth that the stock battery has but this is not an issue at all with the battery as it fits snugly in the battery compartment and the pressure of the spring contacts and the cover help it stay in place just fine with the AGS-001 GBA SP. The AGS-101 SP and After Market Shells might need a shim to make better contact, we will include a 3d printed shim with the battery but you can also print your own using the file below.

    Great replacement battery

    Posted by Kevin W. on Nov 17th 2021

    Works way better than the green Chinese ones (note, did not buy the old-school battery available here on SAG, but they looked very similar). Bought 2 of those, the first one lasted about 4 hours, but the warning light would stay on for about half that time. The 2nd one only lasted about 2 and a half hours with the light coming on for the last 20 minutes.

    This thing lasts about 9 hours on my AGS 101 with an Everdrive.

    An Excellent battery for GBA AGS-101

    Posted by Julio CĂ©sar on Sep 10th 2021

    I've decided to order this battery to revive my GBA AGS-101, I'm from MĂ©xico and it came in 2 days, super fast, this product includes a 3d printed shim that fits perfectly into the battery slot, some friends wants to order this battery too and they're waiting a restock, completely recommended.

    MegaBat800 High Capacity Battery is "highly" recommended.

    Posted by Tony B on Sep 4th 2021

    Easy to install battery and takes about 3 hours to charge. It can easily last past 8 hours depending on your volume and light settings. Great price and great product.

    Game Boy Advance SP Battery

    Posted by Terence Tan on Aug 21st 2021

    Technically the battery is great. Much Better than the ones you can buy from AliExpress. I've left the console for a week and it is still holding a charge. The other ones are barely able to function. The battery does need spacer to push the battery up to the leads though and it is a little 'flimsy' with the wrapping around the battery coming apart. While it doesn't effect the functionality, it doesn't inspire confidence in the build quality.

    Excellent quality aftermarket battery!

    Bought this to replace the ever-expanding battery of my childhood SP, and I am nothing but satisfied with the quality of the battery life. They really weren't kidding about the extended length, and it's allowed for even more nostalgic, reminiscent playtime. Hats off to Stone Age Gamer for the fast shipping and quality service.

    Highly Recommend

    Posted by Sal C. on Jul 14th 2021

    This was my first order form this site and I received it within 3 days! This battery is great. I had been looking for an SP battery for a while and a friend recommended this one. Once fully charged it lasts quite a while - actually feels like it lasts a little longer than I remember the original battery lasting.

    Works as advertised, with warning

    Posted by Frank P. on Jun 13th 2021

    Just put in and charge... got well over 8 hours on the first charge with heavy play. Next few charges have been crazy long.

    One thing: it didn't work when I used the included shim (wtf?). Took out the shim and it worked fine. So, beware a tight fit isn't always the best (giggity).
