[volt-nuts] Datron 1082

[Randy Evans]

Tom,

I would think with 0.08 VDC the battery is dead and all the memory is gone.
 Do you think it would make any difference if I paralleled the leads with a
new one?  I don't have a parts list to know what type the battery is so
it's going to be a challenge to find a direct replacement.  Wish I had a
manual.

Randy
