ME Super/MX Batteries

[aimcompute]

Hi,   I need to pick up some batteries for my MX and ME Super on the way home tonite and don't have the battery types recorded in my wallet. :-(  Can anyone let me know the numbers?  Thanks.   Tom C.   P.S. A beautiful aurora last night with both green and red.  I hope I captured it.  Also, northern hemisphere Lyrid meteor shower peaks in pre-dawn hours of April 22.  Radiant is to N/NE.
