So i bought this SDS100 at a online auction and got a pretty good deal on it. after i got it i noticed it's not charging i'm not seeing the battery voltage on the display if i turn it off the red light comes on and it just blinks while plugged in, but when i turn it on there is no light. i also notice if i hold the scanner in my hand and shack it alittle i feel the battery moving inside of it. anyways i really want to get it working so i don't have to keep it plugged in all the time. Is there anyone on here that has had this issue before that might know what my problem could be. The scanner works fine in ever other regard it's just the battery and charging. I'll had two pictures showing what i mean. Thanks
