What is the BR-2/3A4F?

This is a 4 cell lithium primary battery designed to work in Fanuc 18-T series programmable logic controllers and robot controllers and Fanuc ALPHA iSV, BETA iSV and BETA iSVSP CNC system amplifiers.

I see that the BR-2/3A4F battery is meant for a programmable logic controller for a CNC system. What exactly is a programmable logic controller and CNC?

The BR-2/3A4F battery is used in programmable logic controls (PLCs). PLCs are simply digital computers which control manufacturing processes like robots and CNC machines. PLC’s can be modular with 10’s of inputs and outputs or very large with 1000’s of inputs and outputs. The programs which run the PLC’s require a battery operated memory back-up system and use batteries such as the BR-2/3A4F.

As mentioned above, PLC’s can control CNC machines. CNC’s or computer numerical control, is a process used to control machining tools (lathes, mills, plasma cutters, etc.) Traditionally, machining tools were manually adjusted. A CNC machines automates the process by controlling the movement and actions of these machining tools via a computer which delivers instructions to the tools. Additionally, CNCs can be used to fabricate complex parts due to the precision of the CNC controls as contrasted to the manual controls once used.

What are the specifications of the BR-2/3A4F?

The BR-2/3A4F is a 4 cell lithium ion primary battery with an output of 6 Volts and a capacity of 2900 mAh. Capacity is a measure of the amount of charge a battery can deliver at a specific voltage. The higher the capacity, the longer the battery can run. The BR-2/3A4F has a capacity of 2900 mAh. It has a very low discharge rate which results in a shelf life of 10 years.

The BR-2/34AF measures 1.38 x 1.8 x 1.33 inches.

The BR-2/34AF provides a stable voltage at a broad temperature range (-60°C to 85°C.)

The BR-2/3A4F is a 4 cell primary battery. What exactly does that mean?

Every battery has three components: the anode (negative (-) side), the cathode (positive (+) side) and an electrolyte (a substance that creates a chemical reaction with the anode and cathode.) When the electrolyte reacts with the anode, electrons are produced in a chemical reaction called oxidation. At the same time, the electrolyte also reacts with the cathode in a reaction called reduction. Reduction requires electrons. So the electrons naturally want to travel from the anode to the cathode but the electrolyte makes it difficult. When we create a circuit using electrically conductive materials (wires), the electrons flow from the anode through the circuit and back to the cathode. When we have a device (e.g. a light or a motor) in the circuit, the electrons travel through it to power it.

A cell is simply one anode and cathode separated by the electrolyte. A standard AA battery is a one cell battery. A car battery has 6 cells. The BR-2/3A4F contains 4 cells.

Additionally, there are two types of batteries: primary and secondary. A primary battery simply means it’s a single use battery. Once the chemicals are depleted, the battery is “dead” and is thrown away (or recycled). A secondary battery is a rechargeable battery. The BR-2/3A4F is a single use, primary battery and cannot be recharged.
