I just ordered a few new batteries and am having some troubles with a couple of them. I have a copper shorty that quite a few of my carts won't fit on. An auto XL black that is having the same problem and a purple XL manual that has a jacked button. Can't press it down, won't even budge in any direction. Also, one of my USB chargers in this order just stopped working for me about an hour ago. Anyone else having issues like this? Sent Mark an email yesterday and haven't heard back yet.
