There are several options.

You can build up a hoard of 1.35v mercury batteries. The supplies are drying
up fast but they are out there. Store them in a fridge, not the freezer, and
they should last many years.

You can use the 1.4v ZnAir batteries. Camera stores sell Wien ones the
"right size" for a considerable expense. You can buy them cheap at a drug
store (hearing aid batteries) and use a copper washer to fit them properly.
They can have a very short life span depending on the humidity where you
live.

You can get an electronic adapter called C.R.I.S. from these chaps:

They are slightly thicker than the original mercury battery and some battery
compartment covers will not go all the way home. It still functions fine.

Finally you can send your meter in to have it calibrated to the 1.5v silver
cells. The alkaline cells do not have the right discharge curve and will not
always be accurate.
