Lithium Photo Battery GP 2CR5 — GP brand model 2CR5 1‑P, single cell 6V (photo battery)

The Lithium Photo Battery GP 2CR5 (single cell 6V) is a compact lithium power source designed for photographic equipment and other devices requiring a small high‑voltage cell. It delivers a nominal 6 V output in a cylindrical configuration optimized for cameras, light meters and optical instruments where size, stable voltage and long shelf life are important. The GP 2CR5 is intended as a replacement battery for devices specified to use a 2CR5-type lithium photo cell.

Advantages

This GP 2CR5 photo battery offers a stable nominal voltage and low self-discharge typical of lithium chemistry, providing reliable performance during intermittent or long-term storage. Its compact single‑cell construction makes it suitable for confined battery compartments, and the battery maintains useful capacity over time, supporting devices that depend on steady voltage for accurate measurements or flash operation.

Suitable for

• Film and digital cameras that specify a 2CR5 or equivalent photo cell
• Light meters and exposure meters
• Rangefinders and optical instruments requiring a 6 V compact cell
• Portable photographic accessories such as small flashes and triggers

When it may not be suitable

The GP 2CR5 is not suitable for devices that require rechargeable cells, since it is a primary (non-rechargeable) lithium battery. It may also be inappropriate for equipment that demands higher continuous current than typical photographic devices, or for applications where a different physical battery size or terminal arrangement is specified.

Key specifications

• Chemistry: lithium primary cell
• Nominal voltage: 6 V
• Form factor: single compact cylindrical photo cell
• Typical use: photographic equipment, light meters, optical instruments
• Storage characteristics: low self-discharge for long shelf life

How to use

Install the GP 2CR5 with correct polarity into the device battery compartment and ensure secure contact with the terminals. Observe the device manufacturer’s replacement recommendations and power specifications. Do not attempt to recharge the cell or modify it. Dispose of the used battery according to local regulations for lithium primary batteries.

What to consider before purchase

• Confirm that your device explicitly accepts a 2CR5-type 6 V lithium photo cell
• Verify the physical dimensions and terminal orientation against the device battery compartment
• Decide whether a primary (non-rechargeable) battery is acceptable for your use case
• Check storage and operating temperature requirements in your device manual

Usage recommendations

Store unused batteries in a cool, dry place and install them only when needed. Replace batteries in matching sets and remove exhausted cells promptly to avoid leakage or device malfunction. For high-drain accessories check device specifications to ensure the 2CR5 provides sufficient current for reliable operation.
