CR2 3V Lithium Battery 50 Pack - Long Shelf Life, High Capacity

In this review of the CR2 3V Lithium Battery 50 Pack the bottom line is simple: these cells are a dependable, high-capacity option for gadgets that need short bursts of steady power. The reviewer finds them most useful for photo equipment, flashlights and range finders because of the advertised 800mAh capacity and minimal self-discharge, which together extend run time and storage life. This pack is best for users who need many spare CR2 cells and value long shelf life rather than a rechargeable solution.

Key Features

• Size and Voltage: CR2 3.0V lithium chemistry delivers the correct nominal voltage for cameras and photo equipment that specify CR2 cells.
• Capacity: 800mAh energy capacity provides longer operating time in high drain devices like digital cameras and range finders.
• Long shelf life: Low self-discharge rate means these batteries can last up to 10 years in storage with very little loss of charge.
• High-drain performance: Short and consistent discharge profile supplies the quick bursts of power required by flash units and light meters.
• Pack quantity: Fifty cells make this a practical choice for shops, frequent users, or someone stocking multiple devices.
• Storage guidance: Storing in a cool, dry place and avoiding direct sunlight or intense heat helps preserve capacity and safety.

Who It's For

This battery pack is suited to photographers, outdoor enthusiasts, and technicians who use multiple CR2-powered devices such as flash units, range finders, rifle scopes and specialty cameras. The large quantity and long shelf life make it convenient for people who need reliable spares or who prefer buying in bulk.

Those who should look elsewhere include people who need rechargeable solutions or devices that require CR123A batteries, since these CR2 cells are not interchangeable with CR123A types. Also, owners of certain surveillance camera models that are explicitly incompatible with these cells should avoid this pack.

Pros & Cons

Pros

• Good value for bulk buyers who need a steady supply of CR2 cells for multiple devices.
• Strong runtime for high-drain devices thanks to an 800mAh capacity.
• Very low self-discharge provides up to 10 years of shelf life when stored correctly.
• Consistent burst performance makes these reliable in flash and photo applications.

Cons

• Not compatible with devices that require CR123A batteries and explicitly not recommended for some camera models that list incompatibility.
• Non-rechargeable design means ongoing replacement cost rather than a one-time rechargeable option.

Our Verdict

The CR2 3V Lithium Battery 50 Pack is a practical, cost-effective choice for anyone who relies on multiple CR2-powered devices and values long shelf life and steady burst power. It offers good capacity and consistent performance for flash, photo and range-finding gear, but it is not a substitute for rechargeable cells or CR123A batteries.

Frequently Asked Questions

Are these batteries rechargeable?
No, these CR2 cells are non-rechargeable lithium primary batteries and should be disposed of or recycled according to local regulations after use.

Can I use these instead of CR123A?
No, CR2 and CR123A are different sizes and are not interchangeable; do not substitute them in devices that require CR123A cells.

How should I store these batteries?
Store in a cool, dry environment away from direct sunlight and intense heat to preserve the up to 10-year shelf life.
