Hello everyone, I have a Fluke 773 milliamp process clamp meter, as well as a Fluke 17B+ multimeter.
Both meters call for Alkaline AA batteries.
My concern, especially for the 773, is that alkaline batteries tend to leak after time (maybe only when discharged?), and I don't use this meter too often due to its specialized nature. I would be sick if an alkaline battery leaked in my $1000+ instrument, so I am seeking advice on the best batteries to use in these units.
From
https://www.eevblog.com/forum/beginners/rechargeable-batteries-in-multimeters-etc/, I understand that lithium AA battery voltage could be as high as 1.8V when new, which may cause erroneous readings or damage.
However, I think rechargeable NiMH may lose their charge between uses, causing me a lot of trouble/inconvenience, since "when I need it, I need it NOW."
I would be grateful for recommendations to ensure 1) protection of the instruments, 2) accurate measurements, and 3) longevity of batteries.
Thank you!
