Apr 15, 2001 · I just measured the open circuit voltage of a spent cell and it's reading 3.01 volts. Is this considered "dead"? Being a 3V cell, I would think that is still an acceptable voltage so I'm wondering …

Jun 28, 2012 · So open circuit and loaded voltage are almost the same then. When loaded a bit, a high impedance battery will quickly drop its voltage even if it's got capacity left, where a low impedance …

Jul 13, 2015 · CNN of all places) are split on 1.4V and 1.35V open-circuit voltage as the effective zero point for alkaline cells. The general shape of the discharge curves for loaded cells could be used to …

Dec 19, 2004 · While it does depend on the device, as you can see from the graphs in the datasheet, once you get down to about 1.4V for low load devices / open circuit voltage, or 1.3V under moderate …

Mar 25, 2008 · Which of course, causes the light to be very dim Different types of cell chemistries behave differently when it comes to this, Alkaline can be tested with open circuit voltage to get a …

Jan 10, 2006 · Where: R1 = test resistance Vo = open circuit voltage Vl = voltage under load On one of my CR123s the open circuit voltage was 2.986, voltage under load was 2.610 and the result of the …

Jan 23, 2015 · The open circuit voltage of the charger is irrelevant believe it or not. The voltage drop across the battery is current x intenal resistance + battery voltage. Since the internal resistance of a …

Feb 29, 2004 · If you assume v1 is the open circuit voltage, then v2 is the loaded voltage, and the difference appears across the internal resistance. Knowing the current with the heavier load and you …

Apr 29, 2006 · All of my used up CR123's read right at a out 2.85 volts. I have had some battery miser lights draw a CR123 to a little under 2 volts open circuit, but that is rare. As already noted, the state …

Jun 2, 2009 · I have 2 mn21 nominal voltage 12 volts. What is typical voltage new? One of mine is 11.6 the other is 11.9. Are they depleted?
