Duracell 28387 CR2 3V Lithium Battery 780 Mah 2-pack

Product Description

The DURACELL 28387 is a 2-pack of CR2 3-volt ultra lithium batteries built for high-drain portable electronics. Each cell delivers 780 milliamp-hours (mAh) of capacity, making it a reliable power source for digital cameras, camera flash units, and portable lights. The batteries incorporate Duralock Power Preserve Technology, which maintains charge during storage for up to 10 years. This shelf-life performance is particularly useful for contractors and service technicians who stock backup power supplies for jobsite equipment or low-voltage diagnostic tools.

These CR2 lithium cells are suited for residential and commercial applications where compact, high-energy batteries are required. Common use cases include digital cameras, flash units, portable lighting devices, and other electronics that draw consistent current from a small form-factor cell. The 3-volt lithium chemistry performs across a wide temperature range, making it practical for both indoor and outdoor service environments.

Installation Notes

CR2 batteries are installed by end users and service technicians without specialized tools. Observe polarity markings inside the battery compartment before inserting each cell. Do not mix new and used batteries or combine different battery chemistries in the same device. Dispose of spent lithium batteries in accordance with local regulations, as they are not suitable for standard household trash in many jurisdictions.
