Can a discharge be "too fast" or "too slow" so it can cause a problem? For instance, can I just short-circuit the +/- ? (Okay, assuming fire won't break out :-) I feel that the battery is warm after discharging with the lightbulb. One more question. There is a pop-up window with a "fuel gauge" in a Toshiba T1000SE. Amazingly, I can change the guage. So, I'm beginning to suspect that the reading is not a function of the remaining fuel - that is, it may be a function of initial setting , time and fuel use. (I mean, indirect calculation, not "measurement" of fuel.) If that were true, then it may not be very accurate. Would that also affect the function of the charger/low battery warning? (What will happen if I set the gauge incorrectly in the first place?) -- | Yesterday I was a student.
