Hardware Shopping for a new battery for my GBA-SP

[KimKong]

Hey, I noticed my battery is starting to get a little old and worn out. And I'm wanting to swap it out with a brand new one. But I'm a bit hesitant as to where I'm going to shop for these types of batteries.. Most of my concern come from not wanting a cheap crappy battery that wont last.

I'm looking for a good place to buy new high quality batteries. Anybody know of such a shop..?
Any help is much appreciated!

I got myself a few of these for my SP collection, they work really well.

I wouldn't go with an aliexpress battery. Get one of these. https://www.heldergametech.com/shop/batteries/game-boy-advance-sp-megabat800/

The Helder battery that Plstic recommended is of good quality, along with Helder's other products. If you're not located in the US or UK and are comfortable with minor soldering, Makho's battery mod is also very reliable. Note that it requires you to print your own pcb, but a few vendors carry pre-assembled versions of the mod. Details are in this video:
