Your camera takes a PX625 mercury battery, which is not made anymore. The camera will not meter properly with the alkaline equivalent. However, you can use a 675 zinc air battery (made for hearing aids) and put an o-ring or similar around it to make it fit the battery chamber properly. Alternatively, you can purchase a Criscam MR-9 and use a modern alkaline battery. The adapter attenuates the voltage to the correct amount.
