At long as the battery voltage is the same and the physical size is the same you
should have no problem. Batteries with a higher mAHrs will last longer. Go to
Radioshack and by a regulated 9 volt adapter along with the plug that fits the
Star Diamond. That along with the batteries can keep the Star Diamond powered
for long periods.  Thats what I did.

Batteries that cost 3 times as much, better last at least three times longer
than what they are replacing.
