This replacement battery from Chauvin Arnoux is specifically designed for earth testers C.A 6462, C.A 6470N, and C.A 6471, as well as for the 5 kV insulation testers C.A 654X and C.A 6505. It serves as a rechargeable power supply for these measuring instruments, ensuring reliable and long-lasting energy delivery during field measurements. The battery is based on Nickel-Metal Hydride (NiMH) technology, known for its environmental compatibility and high service life. With a nominal voltage of 9.6 V and a capacity of 3.5 Ah, it provides sufficient energy for multiple measurement cycles, with a charging time of approximately 6 hours.

Applications

The battery is used in professional environments where mobile earth and resistance measurements are required, for example, during testing of protective and functional earthing in industrial plants, buildings, or outdoor locations. It is part of the power supply for devices designed according to the standards IEC 61557 and IEC 61010, enabling safe and precise measurements under challenging conditions. The devices for which this battery is intended measure earth, ground, and transition resistances with an accuracy of ± (2 % + 1 pt) in the range of 0.01 to 2000 Ω.

Functions and Equipment in Detail

The battery is designed for use in robust measuring instruments intended for field applications. It enables continuous power supply without the need for an external mains connection, thereby increasing the mobility and flexibility of measurements. The integrated charging function in the device allows the battery to be recharged during operation or after the measurement process. The charging time is approximately 6 hours, ensuring quick readiness for reuse.

Technology Explained Simply

The NiMH technology offers high energy density and is less susceptible to the memory effect compared to other battery types. The nominal voltage of 9.6 V matches the operating voltage range of the compatible devices, ensuring stable power supply. The capacity of 3.5 Ah enables an average operating time of approximately 1,180 measurements at 15 seconds per measurement, which is sufficient for extensive testing. The power supply is provided by a rechargeable battery integrated into the device and charged via a charger.

Compatibility and Accessories

The battery is compatible with earth testers C.A 6462, C.A 6470N, and C.A 6471, as well as insulation testers C.A 654X and C.A 6505. It is a replacement part intended for maintenance or enhancement of device functionality. Accessories such as test leads (e.g. 50 m, 100 m, 150 m), reels, spools, adapter cable lugs, earth electrodes, and transport bags are available separately. These components support the execution of earth and resistance measurements in the field.

Installation and Mounting

The battery is integrated into the device and is not intended for external connections. Installation is carried out by inserting it into the designated battery compartment of the measuring instrument. Charging is performed via the integrated charger within the device, eliminating the need for additional charging units. Use is restricted exclusively to the specified devices.

Operational Advantages

The battery enables mobile and independent power supply, allowing measurements to be carried out at locations where no mains connection is available. The high capacity and short charging time increase the efficiency of inspections. The use of NiMH technology ensures an environmentally friendly and long-lasting energy source suitable for professional use. Compatibility with multiple devices increases reusability and reduces replacement requirements.
