Every time I come back to my GBA after not using it for a few days the battery will be dead. I will charge it up and play for a bit, but then when I come back to it after letting it sit for a couple days it's always dead and needs to be charged before I can play it again. It also makes a somewhat concerning hissing sound even while it's off. The sound reminds me of the coil whine that'll sometimes come off of the gpu in my pc. Overall I went back to AAs.
Super easy, barely an inconvenience to install.
A while ago I installed an IPS panel, and used one of the pre-cut shells.
I was happy with the results, but it was a pain to keep my rechargable AAs charged, and I had to swap them pretty often.
I got this mod along with the pre-cut battery cover, and it was a breeze to install, looks great, and works great!
Can't stress how neat and modular this battery upgrade is. Definitely recommend this to folks who don't wanna burn through packages on packages of AA batteries (and wallets) while sustainably keeping up with the new V2 IPS screens on the market. The Clean Juice mod elevates old and weary GBAs into long session players.
Easy to install and wonderfully working!
Works like a charm!
