The Fanuc A98L-0031-0012 is probably the most commonly installed backup battery in the world of CNC machining. It is a special 3.0-volt lithium cell of size 2/3 A, which serves in thousands of Fanuc controls (series i) and robot controllers as life insurance for memory.This battery supplies the SRAM memory and the absolute encoder (depending on the place of installation) with power when the machine is switched off. It stores machine parameters, zero points, tool corrections and CNC programmes. As the cell often serves for many years, its replacement is frequently forgotten – until the critical "BAT" alarm appears.Highlights at a glanceOriginal Fanuc specification: The part number A98L-0031-0012 designates the specific cell (often a Panasonic or Sanyo BR-2/3A), which is contained in the Fanuc order number A02B-0200-K102.High energy density (lithium): Uses lithium poly-carbon monofluoride chemistry (Li-CFn). This is not designed for high currents, but for extreme longevity and stable voltage over the years – ideal for memory backup.Format 2/3 A: A compact cylindrical cell (approx. 33.5 mm long) that is shorter than a standard AA battery, but thicker than a CR123A.Ready to plug-in installation: Delivered including cable and the special black Fanuc system connector (JAE 2-pin with locking nose). No soldering required.Long service life: Typically offers an operating period of 3 to 5 years in the CNC machine. The self-discharge is so low that it can be stored for up to 10 years.Critical data protection: Prevents the loss of system parameters (parity error), which on older machines would often mean manual re-entry of hundreds of parameters.Areas of applicationThis battery is found in a very wide range of Fanuc devices:CNC controls: Fanuc Series 0i (0i-Mate, 0i-B, 0i-C, 0i-D), 16i, 18i, 21i, 30i, 31i, 32i.Robot controller: Fanuc R-J3iB, R-30iA Mate (often in the controller housing or in the base of the robot).Power Mate: Series iD, iH.Position: Usually directly behind the screen (LCD) or in a small compartment on the CNC unit inside the control cabinet.Installation & safety instructionsGolden rule: Replace the battery only when control is switched on (Power ON). The system is buffered for only approx. 20 minutes by a capacitor when switched off. If you remove the old battery and have trouble inserting the new one (e.g. connector stuck), the memory is cleared. With the machine switched on, this risk does not exist.Attention high voltage: Work carefully in the control cabinet. Do not touch any live parts near the control.Reset: After the change, the error message ("BAT" flashes or alarm) usually does not have to be acknowledged manually; it disappears as soon as the voltage is > 2.8V again.Connector coding: Pay attention to the "nose" on the black connector. There are similar batteries with brown connectors (different coding) which do not fit mechanically. Do not use force. Features Model / Fanuc Ref.CNC battery A98L-0031-0012 Chemical system**Lithium poly-carbon monofluoride** (BR series) Voltage**3.0 V** Capacityapprox. **1200 mAh** (standard for 2/3A) Format (cell)**2/3 A** (Cylindrical, short and wide) Dimensions (cell)approx. 17 mm Ø x 33.5 mm height Connection**JAE connector 2-pole** (coded for Fanuc board) CompatibilityFanuc Series **0-C, 0-D**, Series **15-B**, 16/18/21 (older revisions), Power Mate iH TypeNon-rechargeable / primary cell Weightapprox. 18 g  FAQs for A98L-0031-0012What is the difference to A98L-0031-0025?That is a big difference!A98L-0031-0012: Small cell (2/3 A), black connector. Mostly for the CNC control (display).A98L-0031-0025: Large cell (type C or D in housing), grey box. Mostly for the servo amplifier (buffering of the axis position). Do not mix these up, they do not fit mechanically.My screen displays "APC Alarm 307" – is this the battery?Probably not. APC alarms (Absolute Pulse Coder) usually refer to the batteries in the axis amplifiers (servo drives), not to the battery in the CNC unit. The battery of the CNC unit usually causes system alarms or a flashing "BAT" in the status line. Check your machine's manual.Why is the battery so expensive compared to supermarket batteries?This is an industrial lithium cell (not alkaline manganese). It has a special chemistry for long-term stability (10 year shelf life) and a very wide temperature range (-40 to +85 degrees), to avoid failure in a hot control cabinet. A standard battery would quickly fail here and cause expensive damage.
