BR-A Lithium Battery with Tabs (3V) — Reliable Primary Power for Industrial Electronics
The BR-A lithium battery with tabs is a primary (non-rechargeable) 3V cylindrical BR-series cell commonly selected for equipment that needs stable, long-life power and an installation method suitable for assemblies—like spot-welding or direct PCB connection. This is Not Panasonic brand.
This style is frequently used for memory backup and real-time clock (RTC) support, and it also appears in many industrial and professional devices where dependable shelf life and low maintenance matter. :contentReference[oaicite:1]{index=1}
Why “Tabs” Matter
Tabbed versions are designed to be integrated into an assembly (battery pack, control board, or harness). Tabs help ensure a secure electrical connection without relying on spring contacts—especially in equipment subject to vibration or long service intervals.
Common Applications
- Memory backup and real-time clocks (RTC)
- Utility metering and automated meter reading (AMR)
- Wireless alarms and security devices
- Emergency location transmitters / beacons
- Industrial/professional electronics (including some PLC-related backup uses)
- Size: (L × W × H) MM 45.40 × 16.64 × 16.50 mm ≈ (1.787 × 0.655 × 0.650 inches)
These use-cases are widely listed by battery suppliers and compatibility references for BR-A/BR-A-TABS style cells.
Specifications (Common for BR-A Type Cells)
- Nominal Voltage: 3.0V :contentReference[oaicite:3]{index=3}
- Typical Capacity: ~1800mAh (varies by manufacturer/variant)
- Size: “A” class cylindrical (approx. 17mm × 45.5mm)
- Chemistry: BR series primary lithium (poly-carbon monofluoride / Li-CFx is commonly specified for BR cells)
- Termination: Solder tabs (tab orientation can vary by version)
Compatibility Notes (Read Before Ordering)
- Confirm tab style & polarity: Tabs come in multiple shapes/orientations (top/bottom/side). Match your original battery.
- Do not recharge: This is a primary lithium cell—charging can be hazardous.
- Verify device requirements: If your device specifies BR-A, BR17455, or BR-A with tabs, this is typically the correct family.
Tip: If you’re unsure, send photos of the old battery (front/back) and the connector/board area. We’ll help you confirm the correct tab layout before shipping.
- BR-A type primary lithium cylindrical cell (BR series)
- 3.0V nominal output
- Solder tabs for secure pack/PCB installation
- Commonly used for RTC & memory backup in industrial electronics
- Frequently found in metering, alarms/security, and professional devices
FAQ — BR-A Lithium Battery with Tabs
Is the BR-A battery rechargeable?
No. BR-A batteries are primary (non-rechargeable) lithium cells.
What is the nominal voltage of a BR-A?
Most BR-A type cells are rated at 3.0V nominal.
What does “with tabs” mean?
“Tabs” are metal solder/spot-weld terminals attached to the battery to connect it to a circuit board or harness—commonly used in industrial assemblies.
What devices typically use BR-A / BR-A-TABS batteries?
Common listings include memory backup, real-time clocks, utility metering/AMR, wireless alarms & security devices, and other professional electronics
How do I make sure I’m ordering the correct tab configuration?
Compare your original battery’s tabs (shape, location, and polarity). If you can, send us a photo of the old battery and mounting area so we can confirm the closest match.
Are BR-A and BR17455 the same?
BR17455 is a common “A-size” BR-series designation often associated with BR-A listings. Always match your device’s part number and the physical tab style.
Commonly listed applications for BR-A / BR-A-TABS style cells include:
– Memory back-up and real-time clocks (RTC)
– Utility metering and Automated Meter Reading (AMR)
– Wireless alarms and security devices
– Emergency location transmitters/beacons
– Professional/industrial electronics (including some PLC-related backup uses)
