Psion Series 5 - Battery Performance Charts by PsLight5 - Lithium


Energizer L91 Lithiums - Thanks to Larry D White. The gaps in the chart are due to PsLight5 being put in the background by another program whilst on chart display or in the configuration dialog (Tip: always use the 'Continue' button) - Still you can see how stable this type maintains it's voltage, although the 46 hour life is a little disappointing given the expense.

Larry comments :- Here is the Battery Chart I promised you on the Energizer L91 Lithiums, again I have a Stock 5mx without a CF card, I used the backlight a lot on this the first 30 hours. Thanks for telling me why I was getting all the gaps, I didn't realize it didn't record when I left the graph open. I was also disappointed with the price/time ratio; they are 6 to 7 times the price of a standard Alkaline but only yield twice the life. The only time I might consider them is when carrying a lot of regular alkalines is not possible or when I might be out away from a store when the batteries quit. I think I will always carry a pair with me for an emergency; they are 1/2 the weight of regular alkalines and have a 10 year shelf life. They also power the backlight for long times with almost no voltage drop
