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.
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.
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…
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?
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".
