Does anyone know where to find, or even look for the QB-35L battery for AnyTone 398UV? I recently got a can't-pass-it-up deal from an eBay seller on this excellent analog hand-held. I always have an extra battery for all my hand-helds. This one is the hardest to find that I have ever come across. I have searched the internet high & low. This post is part of that search.
