Check your battery contacts on/in the radio, battery and charger. Clean with a pencil eraser if needed. If your charger will accommodate the battery alone, try charging the battery outside the radio. Does the charger's light (if any) come on and stay on when the battery/radio is attached? If so, your charger is working properly. If the light (if any) on the charger is flashing you may have a shorted or bad battery. Check your user guide to the radio/charger for more information. Finally, periodically a battery has too low of an initial factory charger to start charging on the charge immediately. Try placing the battery on the charger for 3 complete charge cycles, and see if it will then charge. If the battery is new, you might want to contact the vendor for a replacement.
