Panasonic Pro Power D


Official specifications (I could not find any realspecifications):

  • Up to 80% longer lasting
  • Panasonic’s Pro Power battery offers premium energy for your personal appliances.
  • Developed to provide reliable and dependable power, any place any time.
  • The improved capacity of the new Panasonic Pro Power battery has up to 80% extra performance compared to last years Alkaline ranges.
  • Premium alkaline range: developed to provide reliable and dependable power, any place any time.
  • Ideal for high and medium drain appliances.





This is the largest size of the normal primary batteries and like all alkaline batteries the capacity is very load depend.











The capacity is not only depend on load, but also depend on the minimum voltage that is needed.





The 0.1A trace did take about 7 days to do, but it did give more energy than a 3 days discharge.





Conclusion

These batteries works best at low loads, but you can get about half the energy out of them at 1A load.
I do prefer NiMH or LiIon batteries, they can deliver considerable more power without loosing half the energy.

How is the test done and how to read the charts

thanks for the review, the performance is in accordance with your tests of other alkaline batteries. Since you are testing them I understand why a capacity is never provided with alkalines.

Thanks for the report and the work involved in doing it. Amazing to see that at 1 Amp draw the capacity is more than halved and at 3 Amps the capacity is less than 20% of the 1/10 Amp capacity figure. By 5 Amps the capacity looks to be about 6% of the capacity at 1/10 Amp. Definitely shows the advantage of NiMH batteries for high drain devices. What a test like this cannot show though is the propensity for leakage from the Alkaline batteries too which can be a equipment killer. And yet they probably have 95%+ of the battery market in the USA in the common sizes.

thanks for this test, i’ve always wanted to see a multi current graph for a larger alkaline, it seems to track rather well to an AA battery

Hey Bort you mean that you missed this report when it was first published? That was back in mid February or about 7 months ago. I had the impression that not much got by you! :wink:

I only skim threads in recent posts these days, there are too many new threads to keep track of
