Learn MoreExpectations vs. Reality: Making Sense of Battery Voltage ...
Learn More$begingroup$ That makes sense: as the battery discharges, the internal resistance increases and conversely the resistance of the load decreases in order to mantain the current draw. Thus, there is a bigger drop over the internal resistance, hence a lower cutoff point related to a larger current. I wish there was a constant resistance load …
Learn MoreI left the bike for 5 days and the battery dropped from 12.5v to 11.9v a 0.6v drop. The bike still started. 12 V battery 9.5 Ah sealed lead acid battery. I would like to calculate how long it would take to drop to 11 V or any other voltage for that matter so I know how long it can be left without charging it and still be able to start.
Learn MoreSo, an example: I have 3 lead acid batteries (fully charged) that are from the same place, same make, model, and voltage (kind of, they''re supposed to be 12V each). They have: 12.75V, 12.78V, and 12.85V. This is clearly a range of voltages, but does the .03 drop from one or the .1 drop in the most extreme case matter much?
