[volt-nuts] Affordable batteries for Fluke 732A DC ReferenceStandard?

[Roy Phillips]

Hello Greg
I am sure that you can find a suitable replacement "sealed lead acid" 
battery from a number of sources for considerably less than your quoted 
amount. Due to the content, most of these are made in China or other Far 
Eastern Country - regardless of the "name" of the manufacturer. I have two 
Fluke 731B's, and these use Ni-Cad batteries. As we can see, these were 
"dropped" as a back-up" power source, due to the corrosive damage they 
caused to the PCB.
Regardless, I still get a very good performance from these "ancient" DC 
standards. Incidentally, if anyone finds it hard to obtain information from 
the Fluke US and European websites, try Fluke in  Australia - much more 
generous in manuals for older items.
Roy
