Batteries died on me for the first time. I replaced them and now I'm having issues, when you shake it or tap it, it shorts out or something, I imagine it does this since there is no battery holder, I just taped the wire to the battery, so it must be disconnecting and turn off when you move it a lot. Can I solder directly to the AAA battery? Thats prolly the best way to solve this if its possible, without spending any money.
