Duracell Ultra Lithium CR2 / CR17355 3V 800mAH Lithium Photo Battery

Product Description

High-Performance Camera & Photo Battery

• Designed specifically for high-drain devices like digital cameras, flashes, and portable lighting.

• Uses lithium manganese dioxide (Li/MnO₂) chemistry for reliable power output.

• Provides a stable 3.0 V nominal voltage for consistent performance.

Long Shelf Life & Storage Guarantee

• Features Duracell’s Duralock Power Preserve technology, preserving charge for up to 10 years in storage.

• Ideal for emergency kits, spare batteries for photo gear, or infrequently used devices.

Robust Build & Durability

• Lightweight (~11 g) yet built with a flat recessed negative terminal for secure contact.

• Operates reliably from –20°C to +75°C, making it suitable for both cold and hot environments.

• Low internal resistance (~0.3 Ω) helps deliver high-current pulses with minimal voltage drop.

High Capacity for Demanding Devices

• Rated capacity around 800 mAh, offering extended use compared to many other CR2 cells.

• Exceptional performance under pulsed loads, such as camera flashes or rapid-fire photography.

Precise & Reliable Power Delivery

• Typical voltage under load ranges from 3.2 to 3.3 V, providing solid performance even during demanding use.

• Discharge curves are optimized for photographic duty cycles, maximizing energy per cycle.

Safe, Non-Rechargeable Primary Cell

• This is a single-use (non-rechargeable) primary lithium cell — not designed for recharging.

• Built-in safety features and robust casing help prevent leakage and damage under normal operating conditions.

• Proper handling and disposal are recommended according to battery safety guidelines.

Versatile Compatibility & Equivalents

• IEC designation: CR17355.

• Equivalent to: CR2, DLCR2, ELCR2 (Duracell and other brands).

• Well-suited for a wide variety of electronics beyond photography — such as laser pointers, medical devices, and security equipment.
