Jon--When you remove the batteries and dial out do the LED's still light? I doubt the batteries are your problem as they are generally used only as standby in case of power failure for the telephone auto-dial and other memory requirements within the phone, and the LED's are fed from the power supply plugged into the wall or the tele powerline in some units. You might remove the batteries and dial out and see if the LED's still glow(even weakly) to test that. The LED's are probably supplied thru a transistor or diode switch which may not be turned on hard enough when the telephone is activated due to leakage or open condition, although if leakage the LED's would glow constantly. As a caveat, I have been retired from the electron business for a number of years so maybe Bill Gates or somebody has changed things. Lotta luck. (eom) K

PS The current drain of this type of LED is in the micro-amp range.
