MediaJoy has list of camera batteries and their replacements  MRB625, MRB675 and MRB400.  These photo replacement types only have two air holes, rather then the 7 in standard hearing air replacements.  The hearing-aid batteries need more power over a short time rather then a lower drain over a long time and the two holes allow longer life for the low drain light meters.
