I already have the battery hopeing it will work. I put the battery on the radio but nothing happens. Hoping the battery is just not charged, but I plug the charger in that came with the radio but it doesn't show its charging so maybe I need the correct charger for that battery? I don't know. Anyone with knowledge of this please I need your help. I use the radio all the time and the battery, 1400 mA, doesn't last very long at all.
