Many standard BIOS batteries have 3.0V, but Siemens S5/S7 controllers specifically require 3.0V for Li-SOCl2 technology. A 3.0V battery may be immediately detected as "empty" by the controller.How often should I change the battery?Siemens usually recommends a change every 12 months in the maintenance manual as a preventive measure. At the latest, however, when the battery LED comes on. Since the consequences of data loss are expensive, annual replacement is considered "best practice".Does this battery fit the S7-400?No. The S7-400 series mostly uses larger batteries (often size AA or mono cells buffered in the power supply unit), e.g. part number 6ES7971-0BA00. The 575332TA (1/2 AA) offered here is too small for the 400 series.

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.

The CNC battery A02B-0200-K102 (often identified by the cell part number A98L-0031-0012) is a specialised 3-volt lithium backup battery. It is the life insurance for the control data of your Fanuc i-series (16i, 18i, 21i) as well as compatible machines such as the Le Blonde 77.This battery secures the SRAM memory of the CNC controller. It stores critical data such as CNC parameters, tool offsets, workpiece zero points and the PLC program (ladder). A failure of this battery leads to the immediate loss of this data ("System Parity Error"), which results in a complete machine standstill and a costly restoration of the parameters.Highlights at a glanceOriginal specification: Developed as an exact replacement for the Fanuc order number A02B-0200-K102. The actual cell often bears the identification A98L-0031-0012.High reliability: Uses lithium poly-carbon monofluoride (BR series) chemistry (mostly Panasonic BR-2/3A), which is specially designed for long-term applications with low discharge.Voltage: 3.0 Volt.Capacity: 1,200 mAh (High Capacity for size 2/3 A).Ready to plug in: Delivered as assembly with cable and the specific black 2-pin connector (JAE type), which fits exactly to the Fanuc board.Long life: Typical durability of 3 to 7 years in operation (depending on the operating time of the machine) and up to 10 years shelf life.Areas of applicationThis battery is compatible with a wide range of Fanuc controllers and servo systems, especially:Fanuc Series 16i / 160i / 162iFanuc Series 18i / 180i / 182iFanuc Series 21i / 210i / 212iFanuc Power Mate iD / iHLe Blonde 77 CNC (if equipped with Fanuc control)Location: Mostly behind the LCD display or in a special battery compartment on the CNC unit.Installation & Safety AdviceThe most important rule: Always replace the CNC buffer battery ALWAYS with the machine powered on (Power ON).Reason: If you switch off the machine and remove the old battery, the capacitor on the board will only buffer for about 20-30 minutes. If the replacement takes longer or the capacitor is old, the memory will be erased. With the machine powered on, the power supply provides the memory and the change is safe.Note the alarm: Replace the battery immediately if the display shows the message "BAT" is flashing or the alarm "Battery Low" (often alarm code APC 300 series or system alarm) appears. Do not wait until the next maintenance interval.Position: The battery is often located on the rear of the display unit (MDI/CRT Unit) under a small yellow or black cover. Features Model / Fanuc Ref.CNC battery A02B-0200-K102 (Fanuc) OEM reference (cell)**A98L-0031-0025** (often printed on the housing) Chemical system**Lithium poly-carbon monofluoride** (BR series) Voltage**3.0 V** Capacityapprox. **1200 mAh** Design**2/3 A** (Cylindrical, short) Dimensions (cell)approx. 17 mm Ø x 33.5 mm height Connection**JAE connector 2-pin** (special connector for Fanuc board) CompatibilityFanuc Series **16i, 18i, 21i**, Power Mate iD/iH, 0i-B TypeNon-rechargeable (Not rechargeable!)  FAQs for A02B-0200-K102Is this the battery for the drives (servos) or the controller?The A02B-0200-K102 (A98L-0031-0012) is primarily the battery for the CNC controller (memory backup). For the servo amplifier (absolute axis position) often other batteries are used (e.g. large mono D cells or the A98L-0031-0025 in the black box). Check exactly which alarm message you have ("System Battery" vs. "APC Battery").My battery has a brown connector, this one has a black one. Will this fit?Caution. The connector (JAE) has a mechanical coding (nose).A98L-0031-0012: Black connector (for i-series controllers).A98L-0031-0026 / -0028: Often brown or cream-coloured connector (for Beta drivers or older systems). Compare the nose on the connector exactly with your old part. Forcing it will damage the connection on the expensive CNC board.Can I use a standard CR123A battery?No. Although they look similar, photo batteries (CR123A) have different dimensions and do not have solder tags/connectors. DIY solutions with adhesive tape in vibration-rich CNC machines risk loose contacts and data loss.

The search term "TOSMICREXF" is a common designation (often used by third-party suppliers) for the buffer battery of the Fuji Electric Micrex-F PLC series (Programmable Logic Controller). These controllers were frequently installed in machine tools (also by TOS).The technically correct designation for this battery is usually FBT030A or the underlying cell CR8-LHC. This is a powerful 3.0 volt lithium cell that backs up the RAM memory of the CPU (programmes, parameters, tool data) when the machine is switched off.Highlights at a glanceIdentification: Replaces the original part numbers FBT030A, FBT020A and often CR8-LHC.System compatibility: Especially for the Fuji Micrex-F series (models F30, F50, F55, F70, F80, F80H, F100, F120, F120H).High capacity: Utilises a "high capacity" lithium cell (approx. 3000 mAh) to guarantee the long buffer times of old systems.Ready to plug in: Supplied with cable and the specific white 2-pin connector with locking lug supplied.Long-term protection: Prevents the loss of the PLC programme (ladder logic) and the machine parameters.Important note on the designThere are different batteries within the Micrex-F series. Please check your old part before ordering:The "big one" (described here): Approx. 45 mm long (CR8-LHC / FBT030A). This is the standard for most Micrex-F CPUs.The "little one": Approx. 27 mm long (CR2-L / PM-20). This is rarely used.Connector: The connector of the "TOSMICREXF" is usually white and has a small lug for locking on the circuit board.Assembly & SafetyChange under voltage: To avoid data loss, the battery must be with control switched on (Power ON) must be replaced. Do not switch off the machine while removing the old battery, otherwise the memory will be deleted immediately!Alarm LED: Replace the battery as soon as the red "ALM" or "BATT" LED on the CPU lights up.Reset: For some Micrex-F CPUs, the battery error must be reset after replacement using a reset button or command.Features Model / ReferenceFuji Electric FBT030A (Also: TOSMICREXF) Chemical system**Lithium thionyl chloride** (Li-SOCl2) Rated voltage**3,6 V** Battery capacityapprox. **1600 - 2000 mAh** (depending on cell charge) Design**2/3 A** (often also referred to as ER17/33) Dimensions (cell)approx. 17 mm Ø x 33.5 mm height Connection**Cable with special plug** (white, 2-pin connector, Fuji coding) Compatibility**Fuji Micrex-F** series, **Toshiba PROSEC T** series Battery lifeapprox. 3 to 5 years (in buffer mode) weightapprox. 20 g  FAQs for TOSMICREXF (Fuji FBT030A)What is the difference between FBT020A and FBT030A?The difference lies in the capacity and size.FBT020A (CR6-L): Often has approx. 1600 mAh.FBT030A (CR8-LHC): Has approx. 3000 mAh (high capacity). Both have 3.0V and usually the same white connector. The FBT030A lasts significantly longer and is recommended for machines that are often switched off. Mechanically, the larger FBT030A usually fits into the same holder, as this is often just a clip.Do I have to delete an error after the change?Yes, often. With the Micrex-F series, the "BATT" LED sometimes does not disappear automatically. You may need to press a reset button on the CPU (depending on the CPU model) or acknowledge the alarm in the system menu. Check the manual for your specific control unit (F80, F120 etc.).Can I use a normal photo battery (CR123A)?No. Although both have 3.0 volts, the CR123A has different dimensions and no connector. Soldering on lithium batteries is dangerous (risk of explosion!). In addition, CR123A batteries are often not optimised for years of micro-discharge current (memory backup), but for high currents (flash). Use the original industrial cell for data security.
