These worth keeping?

[Dearslayer]

Had these two units given to me a couple years ago. Was cleaning up today and came across them. Decided to open them up to take a look. Old rechargeable batteries inside are corroded. So are these units worth the trouble or should I ditch them. Where would I get replacement batteries? I checked eBay but most are 3amp and not 3.5. Are any c cell batteries suitable and do they have to be rechargeable?

Thanks I figured as much. Just wanted to make sure.

Watch the cadmium in those older batteries BTW.....

I would have no qualms about cleaning those up and using them. Mind, I do have a "thing" for equipment with large, bright, easy-to-read LED displays

I have quite a few meters from this era that also use rechargeable C-cells, and I have been using the Amazon Basics NiMH (5000mAh!!) with great results. They can be charged using any conventional NiCad charger. Pack of four under twenty buck.

Fluke does make good voltmeters and is a reputable brand. If they are in cal, keep 'em. The batteries are junkers.

 

[Dearslayer]

Do the batteries serve any other function other than making the units portable or are they there as a requirement for the unit to function ?

Keep the Flukes, toss the batteries.

They probably have to be rechargeable if you have it plugged in, but unknown if they are required to function. The manual should tell you. If they are, I like @arts suggestion of NiMH.

Fluke meters are good stuff!
I have a different model Fluke meter with Nicad batteries in it, and the batteries have to be good, and, also, installed, for my meter to function. I have bought the correct Nicad batteries for it twice over the last 25 years from BatteriesPlus.
The charging circuits are different for Nicad and NiMH batteries, use the correct, original type of rechargables.
