Replacement for Chauvin Arnoux Micro-Ohmmeters

This 9.6 V nickel-metal hydride pack replaces the original battery in Chauvin Arnoux models 6547, 6470, 6471, 5050, 6472, 5070, 6505, 6549, 1060, 6430 and 6545. It matches the manufacturer specifications for voltage and chemistry so the instrument powers on and operates as designed. The pack is built to the same physical layout as the OEM unit for a direct fit.

Upgrade from depleted or aged original cells

When the factory-fitted pack no longer holds a charge or shows reduced runtime, this replacement restores full portable operation. The jump is worth it whenever the micro-ohmmeter is used regularly in the field and cannot rely on mains power. It also suits maintenance teams that keep spare packs ready for immediate swap during extended test sessions.

3500 mAh capacity with 33.6 Wh energy rating

The 3500 mAh rating delivers enough capacity for a full day of typical resistance measurements before recharging is needed. Headroom runs out during continuous high-current tests or when the instrument is left on standby for long periods without a top-up charge. Overcharge, over-discharge, over-voltage and short-circuit protection circuits help preserve usable capacity over the service life.

Questions about this item

Will the 202.1 x 50.52 x 17.15 mm pack fit the battery compartment of my CA 6547 micro-ohmmeter?

Yes, those are the exact dimensions of the original 9.6 V 3500 mAh Ni-MH pack used in the CA 6547, 6470, 6471, 5050, 6472, 5070, 6505, 6549, 1060, 6430 and 6545 models.

How do I install the replacement pack, and what step is often missed?

Open the battery door, unplug the old pack's connector, insert the new pack with the same orientation, and firmly seat the connector until it clicks; the step most often missed is verifying the latch is fully engaged before closing the door.

What maintenance or replacement will this 33.6 Wh Ni-MH pack need later?

Store it at about half charge if unused for weeks, cycle it every few months to prevent capacity loss, and replace the pack when run-time on your micro-ohmmeter drops noticeably below the original 3500 mAh rating.
