Battery Level on PX-11 - knife31 - 10-18-2024 12:44 AM Purchased a PX-11 about 5 months ago and really haven't used it that much and my battery died. I didn't check the level when I received it, and it could have been low at the time. Does anyone know what the expected life should or would be. It's my carry around calculator for simple stuff grocery stores etc... I didn't get any batt low indication, however as I said I didn't use it that much so it could have yelled loudly, and I wouldn't have known. Randy So, I just looked at the manual and it says a couple of months. But I think I have a total of an hour of use, so don't know if that's normal or not.

A CR2032 has a capacity of about 235mAh. *Note that the speaker and the backlight consume much more. RE: Battery Level on PX-11 - knife31 - 10-18-2024 01:33 AM Interesting wonder why mine died so early. RH RE: Battery Level on PX-11 - rprosperi - 10-18-2024 12:03 PM Any one battery in any batch can be bad/low, etc. so you really can't reach any conclusion at all, based on a single experience, you need to buy a good quality (Panasonic, Energizer, Toshiba) battery and then experience it's full life cycle before concluding there could be an issue. |
