Hi @TriGlides, that must be frustrating. I have a few tips.
First, get an accurate battery reading. This article shows you how: http://squ.re/1MI5kUg
For best performance, you'll want to charge your reader regularly, especially when you're using it for multiple days at a time. Don't let the reader sit too long between charges. You also will want to make sure the reader isn't sitting on a metal counter or anything conductive, since it'll consume more power and take fewer payments per charge cycle.
If, after going through these tips and best practices, your reader still won't hold a charge, you may need to send it back in to us. Here's how to process a warranty request: http://squ.re/1nBId2z
