The RC 53 battery is a mercury-zinc element in its chemistry and is used in dosimeters, measuring devices, watches, hearing aids, geophysical devices, fire alarm systems, cameras and photo exposure meters.
It has a unique shape with characteristic curves on its surface. These batteries used to be mercury-based, but now stores sell alkaline batteries. Therefore, safety concerns are eliminated.

You can also replace it with a 2Blik-1 battery, which has the following analogs: Duracell PX28A, EnergizerA544 (4LR44); KodakKX28L;
In reality, replacing a full RC 53 battery is quite challenging. Many of its analogs are mercury-based energy sources. When selecting an alternative, make sure the voltage and dimensions match. However, it's unlikely you'll find an identical voltage; it will likely be different. 625The current sources are only the same in size.
When using zinc-air batteries, remember that they start working immediately after unpacking. As a result, they quickly run down.
Alkaline batteries gradually lose voltage during use, which causes incorrect readings on the camera's exposure meter.
