A CNC control can retain programs, alarms, and timing data only as long as its memory supply holds up. A dead battery during a shutdown or voltage dip can turn a small maintenance issue into a much longer restart, so the right choice depends on your control model, battery dimensions, and whether you need standby power for the entire machine.

Why These Options Stand Out
A dead memory cell can disrupt retained settings after a Fanuc control loses power. This five-pack is tailored to the BR-2/3AGCT4A format and several listed Fanuc references, making it a focused maintenance purchase for shops that already know their exact control battery.
The 6V, 4400mAh specification gives you a concrete basis for comparison, but physical fit still matters. Measure the compartment and confirm the connector and markings before ordering; an electrical match alone won’t clear a tight or unusual battery holder.
Strong Points
- Five cells support scheduled replacements across multiple compatible controls.
- The 4400mAh rating suits long-duration memory-retention applications.
- Listed references include Fanuc A06 and 18T series equipment.
- A compact 33 x 34 x 34mm shape fits compatible enclosed holders.
Things To Consider
- It is disposable lithium, so spent cells need responsible local disposal.
- Polarity, connector design, and holder clearance still require confirmation.
Key Specs
Built With In Mind
Maintenance technicians servicing listed Fanuc A06 and 18T systems benefit most from this precisely identified replacement pack.
A Better Fit Elsewhere
Moneyu A98L-0031-0028 suits shops working specifically with the FANUC A02B-0309-K102 module rather than these listed BR-2/3AGCT4A applications.
Unlike the five-cell Beacon Pet pack, Moneyu targets one specific Fanuc module reference. That narrower fit makes it easier to pair with an A02B-0309-K102 controller, provided your documentation confirms both the battery and enclosure part numbers.
For a repair bench handling mixed controls, model-number discipline matters more than nominal capacity. The 3V rating and 1750mAh capacity provide matching criteria, while connector orientation and battery dimensions should be checked against the original cell.
Positive Takeaways
- Specific A98L-0031-0028 and A02B-0309-K102 references simplify identification.
- The 1750mAh rating offers a clear basis for replacement planning.
- Single-cell packaging suits an individual module repair.
Minor Gripes
- Only one cell is included, so inventory planning takes more attention.
- The disposable lithium format isn’t rechargeable.
- Connector details are not supplied, making visual comparison essential.
Core Details
Right Fit For
Technicians maintaining documented A02B-0309-K102 systems will find the model pairing especially useful.
Where Another Pick Shines
Beacon Pet BR-2/3AGCT4A offers a better fit for maintenance teams replacing several listed 6V Fanuc controls from one five-cell pack.
The first two options replace a control’s memory cell, while the CP1500AVRLCD3 supports equipment during an outage. Its line-interactive UPS design, LCD status display, and automatic voltage regulation make it useful around a CNC office, network cabinet, or control-support station with compatible loads.
A simulated sine-wave output deserves attention with sensitive electronics, particularly on a shop floor where motors and variable-frequency drives share the electrical environment. You’d also need to confirm startup demand; a UPS rated for steady consumption can still struggle with abrupt equipment loads.
Real-World Strengths
- AVR reduces minor voltage fluctuations without unnecessary battery transfer.
- The LCD gives you a central view of operating status.
- Surge protection and standby power suit computers and networking equipment.
- The mini-tower format is easier to place beside office-based control gear.
Practical Considerations
- Simulated sine-wave output may not suit every sensitive control.
- Keep the unit ventilated and follow the battery-replacement schedule in its documentation.
Made For
Small shops needing outage support for a CNC office computer and networking equipment benefit more than shops replacing internal memory cells.
Consider Something Else When
GOLDENMATE 1500VA/1000W offers more stated load capacity for a larger group of attached equipment.
Moving from the CyberPower unit to GOLDENMATE increases the stated capacity to 1500VA and 1000W. That headroom suits a CNC support desk, control cabinet electronics, and networking equipment sharing backup power, rather than replacing the primary lithium cell inside a Fanuc module.
The lithium iron phosphate battery system is designed for frequent cycling and a longer stated service life than conventional lead-acid batteries. The catch is compatibility: your CNC system still needs to tolerate the UPS output, and its startup current must fit within the unit’s capability.
What Makes Sense
- The 1000W rating offers more load capacity than the smaller GOLDENMATE choices.
- LiFePO4 chemistry suits frequent backup use and repeated charge cycles.
- One higher-capacity unit can support several low-power devices.
Trade Offs
- A UPS does not replace the control’s dedicated memory battery.
- Size and cooling around the installation area deserve attention.
- Connected equipment must tolerate the inverter’s output waveform.
Feature Snapshot
The Right Fit
Multi-device workshops need broader outage coverage without stepping up to larger machinery loads.
Reach For A Different Pick When
GOLDENMATE 1000VA/600W makes more sense for a smaller group of control-support devices with limited load.
Maintenance inventory benefits from a ten-cell pack, especially across mixed equipment that uses the listed TL-5903, SL-360, and ER14500 formats. The 3.6V, 2400mAh cells are intended for memory retention, real-time clocks, alarms, PLC systems, and listed CNC applications.
This wider compatibility language requires careful checking. A similar AA-sized cell can still differ in chemistry, dimensions, and termination, so you should compare the printed model, holder, and connector before using it as a drop-in replacement.
Why It Works Well
- Ten cells give maintenance teams useful stock for planned replacement dates.
- The 2400mAh capacity is useful for memory and timing functions.
- Listed applications cover Siemens S7-400, PLC, and CNC equipment.
- One pack simplifies ordering across several compatible controllers.
Details To Watch
- The broad equipment references don’t replace an exact model check.
- These are non-rechargeable lithium cells and shouldn’t be placed in a charger.
- Storage near high heat can shorten practical shelf life, so moderate conditions matter.
Who It Suits Best
Service technicians maintaining several PLCs and CNC controls with the exact listed cell format gain the most from bulk inventory.
Skip It When
Beacon Pet BR-2/3AGCT4A is the clearer choice for specified 6V Fanuc controls needing that different cell format.
Between GOLDENMATE’s larger 1000W model and its 600W counterpart, this version offers an 800W rating within the same 1000VA class. That middle position can suit a CNC office, network equipment, and control-support electronics without taking on the higher capacity of the 1500VA unit.
Lithium iron phosphate chemistry is the main ownership advantage because it tolerates frequent cycling better than typical lead-acid alternatives. You still need a load estimate that includes startup behavior, and the UPS output must be compatible with every connected device.
Useful Highlights
- The 800W rating provides useful capacity for several low-power devices.
- LiFePO4 supports frequent charging in an always-ready installation.
- The stated cycle life suits shops planning long-term battery maintenance.
Possible Compromises
- Heavier connected equipment can exceed the 800W rating.
- It remains a UPS rather than a replacement control-memory battery.
- Confirm connector requirements and output compatibility before installation.
Technical Highlights
Who Will Love This
Small workshops with a mixed control desk and modest electronic load will appreciate the capacity balance.
Another Choice May Suit
GOLDENMATE 1000VA/600W better serves installations that need lower rated capacity and simpler load planning.
The 600W version keeps the 1000VA class while lowering the stated power rating, making it a more conservative option for a light CNC support setup. It fits shops that want standby protection for a computer or network device rather than a broad collection of high-load electronics.
The multi-outlet and cooling-focused design details position it as a practical desktop component, although outlet configuration still deserves confirmation. Your connected equipment must remain under the power rating and tolerate the output waveform, particularly in a cabinet containing sensitive controls.
What It Does Well
- The 600W rating creates a clear limit for light control-support loads.
- Multiple outlets simplify connections within a compact equipment group.
- LiFePO4 chemistry supports frequent charge cycles and long-term planning.
Honest Caveats
- Even one higher-demand device can consume much of the 600W allowance.
- Outlet layout may not match every cabinet or regional plug standard.
- Cooling airflow matters during sustained operation in a closed cabinet.
Quick Facts
Whose Shelf It Belongs On
A compact CNC office or lightly equipped control room benefits from the lower 600W load target.
Look Elsewhere When
GOLDENMATE 1000VA/800W is the stronger option for shops that can document a higher electronic load.
Choosing the Right CNC Power Protection
Start by separating two jobs. An internal lithium cell preserves memory, alarms, or clock settings, while a UPS supplies conditioned power during an outage. A replacement battery cannot do the second job, and a UPS does not restore a control whose memory cell has already failed.
For internal cells, match the printed part number first, then voltage, dimensions, chemistry, capacity, connector, and polarity. Photograph the installed battery and record its orientation before removal. This prevents a visually similar cell from becoming an expensive mismatch.
For a UPS, calculate the combined running load of the CNC computer, network equipment, monitor, and other attached electronics. Include startup behavior rather than looking only at average consumption, and leave some capacity margin for future peripherals.
Installation details matter as much as the headline ratings. Place a UPS where it receives cooling, avoid enclosed cabinet corners, and keep cable routing short without blocking ventilation. The lithium choices also require you to follow the manufacturer’s service and charging guidance rather than treating them like disposable control cells.
Common Purchasing Traps in CNC Backup Power
Pitfalls Shoppers Hit
The most consequential mistake is confusing a memory cell with a UPS. Another is matching voltage while overlooking connector polarity, physical size, or exact model references. Always verify documentation before removal.
What Separates Premium From Basic
Higher capacity, lithium chemistry, and more frequent cycling can suit busier installations. A lighter electronics load may make the 600W unit more sensible, so added capacity should follow a measured load rather than a larger number alone.
Frequently Asked Questions
Can a UPS replace a CNC control battery?
No. A UPS supplies operating power, while the internal battery typically preserves memory and timing functions. You may need both for complete protection.
How do I identify the correct replacement cell?
Read the battery marking and control documentation, then confirm part number, voltage, dimensions, chemistry, connector, and polarity. Photograph the original before removal.
Are these lithium cells rechargeable?
The listed replacement cells are non-rechargeable. They should not be placed in a charger or handled as ordinary rechargeable batteries.
Which GOLDENMATE UPS suits a small CNC office?
The 1000VA/600W model offers the lowest stated power rating for light electronic loads. The 800W or 1000W versions make more sense when your connected equipment draws more current.
Does a UPS support CNC machine motors?
A general-purpose UPS generally supports compatible low-power electronics, not the full motor and cutting load of an industrial CNC. Follow the machine manufacturer’s power requirements.
Wrap Up
For memory retention, use the exact internal battery specified for your control. For outage support, choose a UPS according to measured equipment load, startup demand, and output compatibility, with the GOLDENMATE models covering several power levels.
