RE: Woodstock Low Power
I have had my HP-25LP for about a month. I haven't had time to use it extensively, but I bring it out of sleep each day and make a few calculations. I have the GPS and IR-LED options. The GPS requires the boost regulator. I usually turn on the GPS to check accuracy of time and then used the EEX key to turn off the GPS. I always check the battery voltage. My NiMH batteries started out around 2.60 vdc and have remained between 2.53 - 2.59 vdc after one week of very light use. I always use the f-divide key to put it to sleep. If I get a chance, I'll try to make some current measurements when the calculator is in sleep mode, but it will likely be next week before I can get to it. I recall that the HP-25 LP takes <<5mA when running and the LED display is on.
