Hello, These walkie talkies are pretty simple to use. Turn on and turn the volume up and talk. So if you turn it on it is possible for there to be enough juice in the batteries to make the LED function but not enough to modulate (or talk) to the other walkie talkie.

Have you tried to replacing the batteries with new ones yet? Sometimes recharge ables go bad and they are no good when you install them into your item. So make sure the batteries you installed are 'new.' And replace in both units. Should this not work, given the nature of the item and the age of those who will more than likely be using them, they break and soldier joints come loose. The back has a screw that is a specialty tool to remove.

18-24 months. Check your battery for a 3-digit date code.

It is usually a 3 digit number followed by a couple of letters. The numbers tell the date of manufacture. The first number is the year, followed by the week of the year. 025 would be 2010 the 25th week. (or if very old it could be 2000 the 25th week.) If you feel age is not a problem, you might check your charger(s) to see they are fully powered, and clear of debris on the contacts (and the radio contacts as well). Clean with a pencil eraser if needed. A few tips: Be certain when placing your radios on the charge they are turned off.
