Any reason this wont work...?
The stock D3 power supply was 9V @ 700 mA
-thanks!
Should work fine for a time depending on battery capacity, but no way to tell if taking the battery down too far by deck's battery gage when using this type of battery.
D3 DAT deck draws just a bit over half ampere when recording, so if external battery does not have its own gage, make note of its capacity so as not to use it for too long where battery gets over exhausted to not be reliable anymore.
