Test / Review: Panasonic Pro Power AA

Panasonic Pro Power AA



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.




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.

Thanks for this HKJ. I love the official “specs”.

3

It was either leaving out the "Official specifications" section or that sales talk from the Panasonic website.

But Panasonic is not the only one with exaggerated claims: Energizer lithium last 11 times longer? Compared to these it is 3 times longer.

Thanks!

After doing a 3A discharge (test end reached), the cell still has lots of capacity:

2287mAh - 657mAh = 1630mAh

1630mAh could be drained out with a 0.1A discharge i guess ;)

5

Probably not all of the mAh, but I would expect that most of them could. Letting the battery rest would also make it possible to draw 3A again.

If you look at the standard test for alkaline batteries, they are all based on pulsed loads.

6

I love your primary battery tests you do lately. I’m actually discharging some Heavy Duty “D”s right now.
Would be really nice to compare with some regular alkalines. IMHO it won’t be much different.
One more thing could you repeat the 0,1 discharge like 2 weeks later? I believe we’ll get close to 3Ah total.

7

I plan on doing a full set of AAA, AA, C and D cells, all Panasonic Pro Power. I will also test Duracell AA and AAA.

It would have been interesting to do a 0.1A discharge on all cells, but I do have way to many batteries in queue.

8

I mean just the one that has been discharged with 0.1A and sum it up so we get closer to the actual capacity. With those Zn-Cl I’m currently testing I will have to do several “runs” with 0,1A just to get near total capacity. I wish there were lower setting than 0.1A on hobby chargers…

9

I did not mark the batteries or save them.

It is lower on some hobby chargers.

10

Would be nice to include few of some other brands for AA/AAA (Sony,GP…). Not necessarily all the different amperage’s, just 0,1A - that is closest to typical use…
btw could it be with alkies the same as with lithiums - the faster possible discharge, the lower capacity?

RE: I did not mark the batteries or save them.

That’s what I was afraid of!
Wait! You can still find it in a garbage and distinguish by multimeter :bigsmile:

12

My main interest in testing these alkaline batteries, was to compare them to other chemistries (lithium, LiIon and NiMH), not as much comparing different brands of alkaline cells. But there will probably be included a few other brands over time.

For flashlight usage the 1A test is very interesting. There are many other uses for these batteries, mostly at lower current, even below 1mA.

I have not been studying alkaline datasheets, and do not know if capacity and current requires opposite construction. The batteries I tested here was specified as "high current".

13

HKJ, does your pack have a battery code? Here they are marked; LR6XJ/2B
And they have a shelf life of 10years, yours also?

The Panasonic Evolta seems to be the top of their Alkalines.

14

On the 4 pack it says:

Reordernr: LR6PPG/48P, LR6XEG/48P

15

Now there is new battery that I can use in my electric devices.

16

They still have the Evolta on their website: http://www.panasonic-batteries.com/eu/products/primary-batteries/1

17

Evolta is supposed to be the best Panasonic alkaline batteries, Pro Power is second: http://www.panasonic-batteries.com/eu/products/primary-batteries

On the 4 pack it says:

Reordernr: LR6PPG/48P, LR6XEG/48P

Thanks..they are probably different then.

Thanks a lot for the review! Frontpage’d and Sticky’d.
