The most used batteries in film cameras since the late 70’s are; The LR44, CR123a, CR2, CR5 and AA. In older cameras, mercury cell batteries were the most used.

The use of mercury or cadmium batteries such as the PX625 was displaced by alkaline, lithium and silver batteries. This due to the high toxicity that they meant to the environment. The 1.5v LR44 became the standard for most cameras in the 1970s.

It is known as the “watch battery”, button battery or coin battery, since it is used in a large number of consumer electronics such as watches, calculators and of course cameras.

The use of lithium for camera batteries became a standard after the abandonment of mercury. Note that missing batteries do not replace their use in old cameras made for mercury batteries, a better candidate includes the zinc-air batteries that we will see later.

It should be noted that the use of this battery had its peak in the era prior to the advent of autofocus, since only its use was intended to measure light and make shooting speed calculations for Av or Program mode (as in the case of Canon “A” model SLR cameras).
