content: I had a couple of cheapo dead 9V batteries and before throwing them out decided to take the connector off.So i took the label off and when i started peeling the metal case off i noticed that the metal on the inside was yellow.That VARTA logo caught me by surprise.

content: that factory probably makes Varta knockoffs, print on both sides to save metal...

content: Could be a rejected/faulty printing batch, but the already cut and rolled steel strip got recycled by printing on the other side and used for a different brand.

content: They probably are making them for Varta, and when the order is complete they simply carry on running the machinery to use up whatever is left in the batching for the cell chemicals, and then simply flip over the casing sheet and print on the back of it to make the new casings. You probably will find a few Varta cells with the other branding inside the case ( I have seen this) where they were near the end, and put the last roll in with the double print instead of the inner print being a varnish only sealing coat. Remember the chemistry of the zinc carbon cell is very old, and thus all are pretty much the same blend, only the cheaper ones will have a lot more filler material ( often sawdust or chalk) added into the ble3nd to bulk it out and reduce the cost per cell, at the cost of capacity. Adding the filler to the remaining bulk is easy, as you do not have to stop the line but only add to the blender ahead of the pasting operations.

content: Could it be scrap sheet metal?I remember dismantling some cheap headphones. On the other side of the metal cover with a lot of holes, it was red and had what looked like writing on it. I'd post a picture but I no longer have them, as this was 20 years ago.

content: Quote from: Lord of nothing on June 10, 2017, 10:36:35 amMost of the time in the US, the generic is most often the exact same thing, and possibly even from the same factory. You can walk into almost any supermarket here and get the same frozen foods, the same snacks, the same produce, the same everything.Occasionally, the more posh and unreasonable shops have a bigger selection and more obscure foods.Unfortunately, most food in America sucks. Our rules for what companies can do with food, unwritten and government, are very lax. You tend to find an abundance of fillers. It's not all bad, but we currently rank one of the lowest in the world in terms of food quality.

content: QuoteThats true...For example when i compare the real and the fake oreo omg...Every non smoking person could take that the taste different.Its funny when company on a trade fair offer some sweets. On the Product name and taste i could define what kind of quality the products have who the try to sold.Cheap Food cheap quality products. No food -> ass holes.

content: Quote from: jpanhalt on June 10, 2017, 05:40:38 pmAs a global poverty relief charity, Oxfam's definition of "food quality" means a diversified diet and access to safe water - it says nothing about whether that diet is gourmet cuisine or highly processed sugar-laden junk.Overall the US ranks 21st in that table - France and Switzerland are equal 2nd. Sort by diabetes and obesity and the US is among the worst in the world, which drags down their overall ranking.

content: For the criterion of Quality, the US ranks 8th. I was not responding to "overall," because TwoOffFive gave no reference for his assertion. He did say "quality," however, and that chart does address quality as a separate stratification.As for the US's lower overall ranking (it is still in the upper 20th percentile), it is obvious that the "healthy" assessment weighed heavily. As any American knows, junk food diets are a problem and contribute to obesity. But such diets are a matter of individual choice.Neither view is consistent with being one "one of the lowest in the world."John

content: Quote from: Kjelt on June 08, 2017, 07:40:55 pmThe ingredients and/or quality can be completely different so whether something comes from the same factory or not says nothing about the quality of a product.

content: Quote from: nctnico on June 10, 2017, 06:48:36 pmHere, you can generally tell about food just from reading the labels. Ingredients must be listed in order of quantity, and some list actual percentages. If the ingredients and their quantities are the same, chances are the only difference is the brand printed on the label.
