Replacement Battery for Fluke Scopemeter 120 - High Capacity Battery Pack for Fluke 120 Series - Fluke Scopemeter 120 Battery Replacement - Extended Operating Time - Improved Reliability

Bought battery for Fluke123 scopemeter. Fit great and works great

It is good replacement

It works but doesn't last long. It was also a lot less expensive.

Arrived broken. Plastic plug-end was split and couldn’t be plugged into the meter or charged. Cheap knock iff of the Fluke battery. If it arrives intact, it may work, but not worth the price or effort.

I think that I must have not fully seated the plug in the meter on the first try. I did follow the advice here to observe the stock battery plug/pin orientation on first installing the new battery. But after charging for 6 hours, the scopemeter 125 would still only turn on with the stock AC/DC “wall wart” plugged in. I then measured the voltage on the old battery (3.6v) and on this new battery (4.8v), and decided to try again. I put the new battery back in, and (once again) pushed it in as far as it would go with slight pressure. This time the scopemeter worked with battery alone. Yeah!

The battery was as advertised fit perfectly, and works very well.

Battery fit fine and works good.

Works as advertised as a replacement for the old NiCd battery pack that was in my early generation Fluke 123 Scopemeter. It charged up properly when installed and I now have battery-only operation again, freeing me from having to run the instrument with the charger attached. The reason for the four stars and not five is that the 6-pin connector that plugs into the meter is lacking a polarizing (orientation) tab on the housing. This tab helps to keep the connector from being plugged in upside down since there are no polarizing pins installed in the connector to prevent this. Attached is a screen capture for the Fluke 123 service manual that shows the proper orientation - the row with only two wires goes toward the top of the battery compartment as shown.
