I've ordered the batteries solely to replace a dead one in my Pokemon Emerald game on GBA.
As far as the quality of batteries can be reviewed, it's a good one. The only gripe I have with it is that the tabs are quite short, at least they were for Pokemon Emerald. For that game, the battery is placed over a chip, and so the tabs need to be slightly bent (making sure not to break them) and even after doing that, the tabs only go through half the solder joint, since they're so small. So you'll have to be quite precise when soldering them, making sure to leave enough tab length on each side for the solder to catch it properly.
