Does anyone have experience using a mercury sulfate half cell to take nagative and positive plate potential readings in a lead calcium station battery? I am trying to determine the state of charge on each plate.
Does anyone have experience recovering from a low ICV on a large lead acid station battery? One cell in a sixty cell string dropped to 2.13V from the nominal 2.25 reading. We just completed a capacity test a week before the low reading was obtained and the cell along with the bank performed well...
I have a 2W, 500 ohm potentiometer that has erratic resistance readings. Does anyone have a good web link for testing pots? I was thinking about setting up a test rig to put voltage across the pot and monitor the voltage drop across the pot (or across an in-series shunt) as the pot is cycled.
Does anyone have information on the use of water fuses? Certain inverter manufactures have allowed water fuses to be used during troubleshooting in place of normal fuses. This cuts down on the costs of blown fuses. The fuse wire looks like solder and is wrapped around lugs and immersed in water...
I was out inspecting a 60 cell string today and found 7 cells that had a gray like material (a little darker shade than the negative plates) on the bottom of the cells. The material had the consistency of a sponge and was under both the positve and negative plates. Could this be mossing? I...
Does anyone have a good link for fuse failure analysis? I am looking for a site that describes fuse failure characteristics. In particular, I am evaluating a Gould-Shawmut AX25-40.
