Description
The Panasonic 2CR5M is a 6V lithium photo battery sold in packs of two, designed for cameras, flash units, and other high-drain electronic devices that require compact, high-voltage power. Each battery measures approximately 45mm × 34mm × 17mm and uses lithium chemistry to deliver stable voltage output across the battery's discharge cycle.
The 2CR5M is commonly found in film cameras (particularly autofocus SLRs from the 1990s-2000s), some digital cameras, medical equipment, and professional lighting gear. The lithium chemistry allows the battery to operate in temperatures from -20°C to +65°C, making it suitable for outdoor photography in winter conditions or hot-climate use where alkaline batteries would fail. The 10-year shelf life means spare batteries can be stored for long periods without significant self-discharge.
Each battery weighs approximately 25g and provides higher energy density than equivalent alkaline cells, which translates to longer runtime in motorised camera functions (film advance, autofocus motors) and faster flash recycling times. The cylindrical cell construction inside the 2CR5M housing gives it resistance to vibration and impact compared to stacked coin-cell alternatives. This pack contains two batteries, sealed in blister packaging.

Frequently Asked
What devices use 2CR5M batteries?
The 2CR5M is most commonly found in film cameras with autofocus and motor drive (Canon EOS, Nikon F-series, Minolta Dynax models from the 1990s), some digital cameras, professional flash units, and medical diagnostic equipment. Check your device's battery compartment or manual to confirm compatibility.
How long does a 2CR5M battery last?
Runtime depends on the device. In a film camera the battery typically lasts 50-100 rolls of 36-exposure film depending on flash use and autofocus frequency. In low-drain devices the 10-year shelf life often exceeds the operational lifespan of the equipment.
Can I use rechargeable alternatives?
The 2CR5M is a primary (non-rechargeable) lithium cell. Some devices accept a rechargeable 2CR5 equivalent using different chemistry, but this requires checking the device manual for voltage tolerance. Do not attempt to recharge a 2CR5M lithium cell.
What temperature range can it handle?
The 2CR5M operates from -20°C to +65°C. This makes it suitable for winter outdoor photography where alkaline batteries lose capacity rapidly in sub-zero temperatures, and for use in hot climates or enclosed equipment housings.
