Frequently Asked Questions
Can I charge a battery without the radio attached? Yes. The charging pocket is precisely molded to charge either a standalone battery or a battery while it is attached to the radio handset.
What does the amber (yellow) light mean? An amber light indicates the charger has detected the need for a reconditioning cycle. This process calibrates the battery and removes memory effect to ensure maximum capacity.
Is it safe to leave the radio in the charger overnight? Yes. Once the LED turns solid green, the charger enters a maintenance mode that maintains full charge without overcharging or damaging the cells.
