1. Exell A32PX 6V Alkaline Battery PX32A TR164A EN164A
This direct replacement simplicity earned its spot on my list because it requires zero modifications or adapters. You simply drop the cell into the chamber and start shooting.

Buyers note that dropping this cell straight into the camera saves time and effort.
Users appreciate having an immediate power source without tracking down separate converters.
Some photographers mention monitoring the voltage drop as the battery ages.

Choosing Between Them
You will get the best results by matching your shooting habits with the right power solution. My top recommendation is the FASTROHY Battery Adapter because it solves the classic power shortage reliably, though finding the specific internal battery requires some patience. If you prefer avoiding sleeves altogether, the Exell A32PX stands ready for immediate drop-in use.
Keep in mind that older electronics require clean contacts regardless of which power source you choose. Taking a moment to clean any residual corrosion from the battery compartment ensures your meter operates at peak accuracy.
