A final point worth noting is that an ‘upmarket’ commercial meter such as the Fluke 87 can measure low resistance to the same or better order of accuracy. A specific instruction given in an “Applications Note” on low resistance measurement, is to connect leads together and internally record...

acquisition device (GL820, GRAPHTEC, Yokohama, Japan) with a 1 s interval. A load resistance of 100 kΩ was used to flow the current across the circuit. The resistances of the pencil-traced electrodes and Ni-coated paper were measured using a multi-meter (Fluke-115, Fluke, Everett, ...
is easily explained by the small draw from always-connected accessories when the truck is "off" for extended periods of time. My own car will deplete a battery in two weeks if I don't remove the cable from the terminal (stays viable for months if cable removed). Batteries are tricky lit...
If that high of a draw was continuous, the battery would eventually wind up well done (and needing BBQ sauce). I have two smart chargers, a BC900 and a BC700, both by La Crosse. The BC700 has more than enough capacity for charging up to four AAs or AAAs (you can mix the two ...
The primary drawback of RFBs is lower energy density compared to other ECCS. VRFBs have several disadvantages that currently prevent this technology from being widely used and extending its lifespan. There are issues with electrolyte degradation, membrane crossing, self-discharge, restricted reactivity...
