How can you tell how much battery is left in a TI-84 calculator?

You can remove the batteries and test their voltages individually. Looking at the weakest one, 1.50 or more volts is good and will have a long life. 1.0 volts or less is almost dead. Sometimes you can tell the battery is weak by the contrast on the screen, but that's a matter of experience with that calculator.
