Replacement batteries for Chinon cameras

Simple Code - a battery with an "A" usually means it's Alkaline, an "S" is silver an "L" or "DR" is Lithium.  Lithium batteries last longer but are more expensive so you have to determine how much you use your camera and flash (built in flashes use the camera battery)
See bottom of page for more equivalent batteries - Many are the same!
 

Alkaline button batteries: LR44 equivalent to G13, A76, 357, 303, PX76A, PX675A, KA76, V13GA, LR44P, AG13

Silver Oxide button batteries: SR44 equivalent to MS76, EPX76, S76, SP76, KS76, V76PX, RS76, SR44P, SG-13, S15, 11077SOP, B-SR44, 76, 4075

So most of the cameras can use either of the two, LR44 or SR44 or their equivalents. The Silver Oxide will last longer and cost only a bit more.  SR44 batteries are used in lots of laser pointers so they are available and a bit cheaper at times.

Chinon CS and CXII: These take the old mercury batteries that are no longer sold in stores.  The mercury content in the battery, however small, is very dangerous expecially if swallowed by a child or animal.  If you have an old mercury battery PLEASE dispose of it at the many "battery return sites" at Radio Shack, Sears or Walmart.  They dispose of them properly.  The problem is the mercury batteries are 1.35 volts and the "replacements" are 1.5.  That little voltage adjustment could make your negatives underexposed.  Since these cameras are "manual ASA adjustments" you can set a 400 ASA film to 325 to compensate for the over-voltage.  Check the negatives, ask the people at a the photo booth about the negatives and look at the pictures to make sure the new higher voltage battery is working correctly
.
Please check for Wein replacement zinc-air batteries numbers MRB625, MRB 675 and MRB400.  These photo replacement type 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.

You can also purchase a battery adaptor for $20.  This item goes into the battery spot but contains electronics to drop the voltage and uses a standard battery. The adaptor will work for many years and you only have to replace the battery inside the unit, not the whole unit.  Two units are available.
