SOURCE: lost power supply
Hi,
If the desktop charger is the version that can accommodate two radios simultaneously similar to the T5000, then the AC wall adapter or the power supply is 9 volts AC.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

If radios are brand new then I would take them back to the store for warranty exchange. The other opton is to vist a local radio service center and ask the tech to jump the battery. if the battery falls below a certain voltage it might need a quick jump sart from a power supply with a higher voltage normally 12 volts works well...
First put the dead laptop battery in a zip lock.
Then put the zip into refrigeratory and keep it in freezer for 14 - 15 hours.
Afer waitinf for a long time, take the dead laptop battery out of refrigeratory .
Using clean and soft cloth to dry the battery and get the battery to room temperature (about 20° - 25°)
In the end fully charging and discharging the battery for 3 - 4 cycles.
Now you would see that your dead battery holding up charge for 1-2 hours.

SOURCE: my charger will not charge
1) Clean the battery contacts on the radio, battery and charger with a pencil eraser.
2) Test the charger by turning the radio on while attached to the charger (do NOT transmit, as this may cause damage to the unit). If the light on the charger comes on while the radio is turned on, you have a good charger, and a bad battery.
3) If the above test detects a bad battery, replace the battery.
4) Not sure if the battery is bad? Trade the battery out of a known good unit into this one to see if it solves the problem.
