Sorry I didn't get back to you all sooner. My four original
batteries are now down to three and they are going downhill
fast. I'm in California (to WHDigital) and tried e-mailing
one of the dealers; they weren't helpful. Just emailed
RTI. I'm thinking of just rigging a four AA cell NIMH
battery holder to the gutted original battery case and
chargeing them with the proper charger when needed. The
voltage would be right but there would be lots more mAh
so charging wouldn't be needed often. It would look like
s**t but work.
