Hi Cyclin, I will get onto taking a pick tomorrow. Mind you I don't know if even instructions will help me understand the thing.
Sound like your battery is toast. If you post a picture of your "battery gadget" I can find you either instructions or the actual product manual
If the gadget has a box that'd be perfect to see, or if the gadget itself has a model number or info on it that would help too![]()

Mine like knocking me around (big labs)

Awful
