    Default Test/Review of Panasonic Pro Power AA

    Panasonic Pro Power AA



    Official specifications (I could not find any real specifications):
    • Up to 80% longer lasting
    • Panasonicís 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.




    As can be seen on the numbers and on all the curves: alkaline batteries does not handle a high load very well.



















    Conclusion

    According to specifications, these batteries are much better than anything Panasonic has sold before, but looking at the curves they are not very impressive for flashlight usage.
    Being the first alkalines I test, I cannot say how well they compare to other brands.

    Excellent test review. HKJ!

    Thanks a lot. Hope you will be able to review other brand's AA batteries.

    I plan to test AAA, AA, C and D of the Panasonic Pro Power, I do also have test data from Energizer lithium-iron (i.e. 1.5 volt) batteries.
    Later on I expect to test Duracell AAA and AA.

    no internal resistance test? Or does it not matter so much with alkaline batteries?

    It would have required an extra battery to test that and I do not believe that value is that important.

    According to the results, it`s all marketing hype and nothing more, i will stick with Eneloop AA thank-you.

    Nice test HKJ

    Amazing the capacity difference between high and low currents. Just goes to show you how dumb it is to run Alkaline cells in a high output flashlight. Quality Ni-mh cells there is not a large difference in capacity at various discharge currents.

    Yes, either NiMH or Lithium.

    How can i find how much current a device is using? These 2 devices have different current because of the increased power that the blood pressure monitor needs?

    The easiest way is to use a lab power supply instead of the batteries. Using a DMM is also possible but most more fiddly.

    I thought there is an easier way than using a power supply . Usually devices than need more power (such as blood pressure monitors, toys, flashlights, electrical toothbrush) use more current than devices that need less power such as digital audio recorders and radio, or it has also to do with the volt being 1.5 and 1.2 and difference plays a greater role in which battery is best?

    Page EN8 of the omron manual indicates 1000 tests for a set of alkaline batteries. Surprisingly little power required.
