Energizer 4LR44 2-Pack

Keep your iconic electronic SLRs, rangefinders, and light-metering circuits firing with pinpoint accuracy. This is a genuine Twin Pack (2x Batteries) of Energizer 4LR44 6V Alkaline batteries (also widely designated as A544, PX28A, or 476A).

The 4LR44 is one of the most critical power sources for the golden generation of late-1970s and 1980s film gear. Designed as a compact 6-volt block composed of four internal 1.5V button cells, it supplies steady, dependable voltage to drive electromagnetic shutter curtains, internal light meters, and exposure computers. A fresh spare in your bag ensures an unexpected flat battery never leaves your mirror locked up mid-shoot.

The Highlights

• Value Twin Pack (2x Cells): Pop one fresh battery straight into your camera body and tuck the second into your bag or studio drawer so you are never caught out in the field.

• Stable Shutter & Metering Voltage: Many vintage electronic cameras rely directly on battery voltage for precise shutter timing (e.g. the Canon AE-1’s electronically timed cloth shutter). Energizer cells deliver steady output to keep your timings accurate across all speeds.

• Leak-Resistant Casing: Vintage battery compartments and delicate electronic battery doors are notoriously hard to replace. Energizer’s sealed construction guards against destructive acid leaks and terminal corrosion.

• Multi-Year Shelf Life: Formulated with high-purity alkaline chemistry to hold power reliably in storage, ready to go whenever you pick up your camera.
