Description

The Energizer CR2 is a 3V lithium battery designed for high-drain devices requiring quick bursts of power or sustained operation over extended periods. The CR2 cell format measures 27mm length x 15.6mm diameter and delivers stable voltage output across its discharge cycle, making it suitable for digital cameras, professional camera flash units, rifle scopes, night-vision equipment and security sensors.

Lithium chemistry provides higher energy density than alkaline alternatives, allowing the CR2 to power devices that would drain alkaline batteries too quickly. The battery performs across a temperature range of -40°C to +60°C, maintaining output in cold outdoor conditions where alkaline cells lose capacity. The 10-year shelf life means the battery can be stored in camera bags, emergency kits or equipment cases without significant self-discharge.

This single-pack format suits users replacing a depleted CR2 in a specific device rather than stocking multiple batteries. The blister packaging protects the battery terminal from shorting during storage and the cell itself weighs just 11 grams, adding minimal weight to portable equipment. The CR2 is part of Energizer's Specialist range, which covers less common battery formats used in photography, medical devices and industrial sensors.

Frequently Asked

What devices use CR2 batteries?

CR2 batteries are commonly used in digital cameras, professional camera flash units, rifle scopes, night-vision equipment, laser pointers, security sensors and some medical devices. They suit high-drain devices requiring stable voltage output.

How long does a CR2 battery last in storage?

Energizer CR2 lithium batteries carry a 10-year shelf life when stored at room temperature in their original packaging. This makes them suitable for emergency kits and backup equipment where the battery may sit unused for extended periods.

Can CR2 batteries be recharged?

No. The Energizer CR2 is a primary lithium cell designed for single-use. Attempting to recharge a non-rechargeable lithium battery can cause leakage, rupture or fire. Rechargeable CR2 equivalents exist but use different chemistry and require compatible chargers.

What is the voltage of a CR2 battery?

The CR2 provides 3V nominal voltage. This is higher than the 1.5V of AA or AAA alkaline cells, which is why devices designed for CR2 batteries cannot substitute standard alkaline batteries without voltage conversion.
