I just bought 4 new DSE 801 Penstyle batteries, not the auto or usb type - the 4 I just ordered, two passthrou and two regular have all had the little black buttons go inside, happening over and over again and are really just useless. Want to find Sealed DSE 801 regular batteries that I can purchase and hope someone has suggestions on where to buy them, would really appreciate any info on good sealed manual battery. Thanks a lot, Darlene
