Fuji Special CR8-LHC for Fuji Electric - 3V Lithium SPS battery
Description
Product information
The Fuji Special CR8-LHC is a high-capacity lithium buffer battery specially designed for the Fuji Electric Micrex-F and Micrex-SX PLC control series. This 3.0-volt power source secures the internal RAM memory.
The addition "LHC" (High Capacity) indicates a particularly high energy density. Compared to standard buffer batteries, this model offers an extended service life, significantly prolonging maintenance intervals in large industrial plants. It reliably protects your programmes, machine data and calibration values from loss in the event of power failure or system shutdown.
Highlights at a glance
- Specific for Fuji Electric: Perfect replacement for part numbers CR8-LHC, FBT020A or FBT030A (please compare plug).
- High Capacity (3000 mAh): With a capacity of about 3000 mAh this cell provides an extremely high energy reserve. This is especially important for older controllers or systems with long downtimes.
- Lithium technology: Uses lithium manganese dioxide (Li-MnO2) for a stable voltage of 3.0 V throughout the entire lifetime.
- Ready to install: The battery is supplied as an assembly, including cable and the specific white system connector (often with latch), exactly fitting the CPU board.
- Long lifetime: Thanks to extremely low self-discharge (< 1% per year) the battery can be stored for up to 10 years and often lasts 5+ years in operation.
- Industrial quality: The cylindrical steel housing protects against leakage and withstands typical vibrations in control cabinets.
Areas of application
This battery is primarily found in the following systems:
- Fuji Electric Micrex-F series: F30, F50, F55, F70, F80, F80H, F120, F120H.
- Fuji Electric Micrex-SX series: SPH, SPB.
- Various CNC controls: Based on Fuji hardware.
Installation & safety instructions
- Replacement under voltage: As with almost all PLC systems, the battery must be replaced while the controller is powered (Power ON) to avoid data loss.
- Observe alarm: The CPU usually indicates a weak battery with an LED (BATT or ALM). Do not delay replacement, as the remaining runtime is often just a few weeks.
- Plug check: There are various versions of Fuji batteries. Compare your old plug to the spare part. The CR8-LHC usually has a slightly larger, white plug compared to the smaller CR2-L versions.
- Reset: After installing the new battery, the battery error must often be cleared by a reset or restart (see CPU manual).

FAQs for Fuji CR8-LHC
What is the difference to CR6-L or CR2-L?
The difference is in the size and capacity.
- CR2-L: Small, short cell (often for compact CPUs).
- CR6-L: Medium size.
- CR8-LHC: Large cell (approx. 45mm long) with the highest capacity (3000mAh) for maximum buffer time. Mechanically, they often do not fit in the same holder, so the part number is crucial.
Can I recharge the battery?
No, absolutely not. This is a primary cell (disposable). Attempting to charge can cause an explosion or chemical leakage, which would destroy the expensive PLC board.
How long can I store the battery?
Thanks to lithium technology, you can easily store this battery for 10 years on the shelf (at room temperature). It is advisable to always keep a spare battery in stock so that you can react immediately in the event of an alarm.Properties

The PANASONIC BR-CCF2TH is a highly specialised 6-volt lithium battery pack developed for fail-safe memory backup in demanding CNC control systems. Based on the extremely reliable lithium polycarbon monofluoride technology (Li-(CF)n) and assembled into a robust unit of two C-cells, this pack offers exceptionally long service life and operational reliability, especially in environments with high temperatures.Highlights at a glanceMaximum reliability: Developed for fail-safe buffering of programme memories in CNC and PLC control systems.Extreme longevity: Very low self-discharge and a service life of up to 10 years.High temperature range: Guarantees stable performance over a wide operating temperature range from -40 °C to +85 °C.Very high capacity: 5000 mAh for maximum self-sufficiency and long replacement intervals.Ready to connect: Equipped with the appropriate cable and connector for fast and error-free installation.Fail-safe energy for CNC machinesThe PANASONIC BR-CCF2TH battery pack is the preferred power source for memory buffering in a wide range of machine tools. It is typically used in CNC control units (e.g. from Fanuc) and other industrial computers. Its main task is to reliably maintain the volatile programme memories (SRAM), tool data and system parameters in the event of a power failure or when the machine is switched off, thus preventing costly data loss, machine downtime and time-consuming reprogramming.Superior lithium polycarbon monofluoride technologyLithium polycarbon monofluoride technology (BR series) is the key to this battery pack's exceptional reliability. In comparison to lithium manganese dioxide technology (CR series), it offers even lower self-discharge and superior performance at very high ambient temperatures, such as those often present in industrial machine cabinets. This guarantees maximum operational reliability throughout the long service life.Developed for professional applicationThis battery pack is designed as a direct replacement and OEM component. The assembly of the two cells with the specific connector plug ensures rapid, simple and, above all, reverse-polarity-proof replacement by technical staff. The high manufacturing quality ensures a permanently reliable connection even under the vibrations of machine operation.

The very low self-discharge ensures that the battery remains ready for use for many years, making it ideal for low-maintenance backup applications in industrial control systems.Is this battery pack rechargeable?No. This is a lithium primary battery. It must not be attempted to be recharged under any circumstances. Charging attempts are extremely dangerous and can lead to fire or explosion.Why is the special connector so important?The pre-assembled connector is precisely matched to the connections of specific CNC controllers. This enables fast "plug-and-play" replacement and its coding prevents incorrect polarity, which could destroy the sensitive control electronics.How often does this battery need to be replaced?The replacement intervals depend on the control unit and the ambient conditions and are specified by the machine manufacturer. As a rule, the CNC controller itself signals when the backup battery voltage drops and replacement is required.How should this battery be disposed of?Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please take the empty battery to the designated industrial or municipal collection facilities to ensure proper and environmentally friendly recycling.
