This is Panasonics top of the line alkaline batteries, they are supposed to have the highest capacity, but they only has that at very low load.
As usual alkaline batteries are very sensitive to load.
Conclusion
I am not very impressed with this battery, they only case where it has extra capacity is at very low loads.
Notes and links
Battery manufacturer tests battery another way, where the battery is loaded for a short time and then has some rest, this may give this battery an advantage.
Now at least I know I won't buy these for back up, not even for my parents in law.. these are the ones that are popular (available in every store), and they go for about $1 per piece.
I looked at the packaging in Aldi today and they have a bar chart showing the performance of these compared to Pro Power and their standard alkalines. Evolta should be the best if they are to be believed, but…well I wont be buying them again!
