Exell Battery CR425 3.0V LiMnO2 Pin-Shape Battery – 25mAh for Fishing Lures, Floats, LED Flashers

Overview

The Exell Battery CR425 is a compact 3.0 V pin‑shape lithium manganese dioxide cell designed for small, non‑rechargeable devices. With a slender 4 mm diameter and 25 mm length, it delivers steady energy in tight spaces while keeping a lightweight profile. Originally developed for lure applications on large fishing fleets, this cell doubles as a practical replacement option for BR425 devices, offering dependable power in a tiny package.

Performance, longevity, and everyday use

Equipped with a 25 mAh capacity and a nominal discharge around 3 mA, the CR425 aims for reliable operation in low‑drain applications. A low self‑discharge rate helps keep stock ready for use over time, making it a sensible choice for seasonal or occasional equipment that sits idle for extended periods.

• Long shelf life up to 20 years when stored properly
• Low self‑discharge supports readiness after long storage

Typical uses and benefits

Ideal for tiny devices that require compact power, such as fishing lures with LEDs, illuminated floats, pole lights, and night signaling aids. It also suits compact microphones, PDA pens, and arrow nocks where space is at a premium. The pin shape makes installation easier in slim housings while maintaining stable output.

• Small, precise energy for slim enclosures
• Non‑rechargeable design reduces maintenance and replacements
