That's bullshit!

As noted in a previous post, I acquired a Dreamcast, it turns out that the system needed a new clock battery. I replaced that. The VMU needs new batteries after just 3 months. I have an ancient infant toy from when I was just a wee one whose battery(ies) are still good after 27 years! Seriously, What the flying flimp is going on when modern batteries die after barely being used for just 3 months, whereas older manufacturing methods could create better stuff!
