Test/review of Panasonic Super Heavy Duty AAA CAN

[size=+3]Panasonic Super Heavy Duty AAA CAN[/size]



Official specifications:

• Nominal voltage: 1.5V

Carbon-Zinc AAA batteries from Panasonic.












This type of batteries has a rather bad performance.







Even at 10mA discharge the capacity is rather low.





[size=+3]Conclusion[/size]

This type of batteries may be very cheap, but the energy contest is also very low and they cannot deliver much power.

I got the batteries from: a Canadian appreciative of the work HKJ does and shares

How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

So they are called "Super Heavy Duty" now? I can recall that some years ago the blue mark meant "Standard" (which was the lowest-capacity Zinc-Carbon cells they carried), then there were red "Super" and green "Green", and then Alkaline. Oh, right, they only say "Super Heavy Duty" on the package, but the cells themselves are just called "Carbon Zinc", which would be pretty close to "Standard". ;-) They still carry the characteristic red and blue rings around the positive and negative pole, the same one Philips batteries carried (and have carried since the early 80's), although those once were made in Belgium and carried slightly different labels (blue were "Standard" and discontinued around 1985, red were "Super", green were "Green Line" from 1987 on, and Alkalines were a completely different color set and available in multiple variations.

In the early 90s I had some blue Standard and General Purpose versions of them. Later, Standard changed to Plus and red and silver ones were introduced, called Special and Ultra. The silver ones were zinc chloride chemistry.

There are at least two generation of Zinc Carbon, the first one was Zinc carbon the next Zinc chloride and that change got the "heavy duty" or "extra heavy duty" name on the cells or something else, two or 3 of the above Panasonic is probably the chloride version.
