Product Details and Uses

Nash Siren R3 / S5R Receiver Batteries (CR123A)

Never let a dead battery compromise your session awareness. Engineered specifically to meet the high-drain, digital demands of your bite indication setup, these premium CR123A 3V Lithium cells ensure your Nash Siren R3 or S5R receiver remains reliably powered. When you are sleeping out or monitoring rods from inside a bivvy, these high-output cells offer optimum performance that far outlasts cheap, standard alternatives.

High-Performance Digital Cells

Modern bite indicator receivers process constant wireless data, multi-tone audio, and high-intensity LED outputs simultaneously. These specialized lithium cells are designed to handle those rapid current draws without suffering sudden voltage drops.

Built with advanced Lithium chemistry, these batteries boast an exceptional operational temperature range, working flawlessly from searing summer heatwaves down to freezing winter nights (as low as -40°C). Furthermore, they feature an incredibly long shelf life, meaning you can confidently store a spare pack in your tackle box for seasons to come without losing charge.

⚠️ Critical Compatibility Note

Make sure you are buying the correct power source for your specific Nash setup.

This Product (CR123A 3V): Fits the Siren R3 Receiver and Siren S5R Receiver.

Alternative (CR2 3V): Fits the actual Siren R3 and S5R Bite Alarm Heads themselves.

Pro Tip

Bite alarm receivers consume significantly more power when set to high volume combined with vibration mode. To maximize your receiver’s battery life during long sessions, drop the master volume down a notch and rely on the vibration alert if the receiver is clipped to your belt or resting right next to your bedchair. Always remove the battery at the end of the season if your gear is going into long-term winter storage to eliminate any risk of slow parasitic drain.

Ideal Applications

Long-Stay Carp Campaigns: Essential for week-long sessions or French trips where your receiver is switched on 24/7.
Sub-Zero Winter Sessions: Perfect for freezing winter carping when cheap alkaline batteries lose their power and fail unexpectedly.
Emergency Spares: An absolute tackle box staple that ensures you’re never caught short when your receiver gives you the low-battery warning tone on the bank.

Frequently Asked Questions

Will this battery fit the actual Nash Siren R3 bite alarm head?

No. The R3 and S5R bite alarm heads take a smaller CR2 3V Lithium battery. This CR123A battery is slightly larger and is designed exclusively to fit the Receivers.

How long can I expect one of these batteries to last in my receiver?

Under normal fishing conditions, a high-quality CR123A cell will comfortably power your receiver for multiple months of active angling. However, heavy action, leaving the unit turned on in your luggage, or running maximum volume/vibration will naturally reduce this lifespan.

Are these cells rechargeable?

No, these are standard single-use lithium cells engineered for maximum power capacity and steady voltage discharge. Do not attempt to place them in a standard battery charger.
