Very often, when I write about batteries, I come across two prejudices:
1. Only salt batteries flow;
2. Expensive alkaline batteries definitely cannot leak.
The photo shows a very expensive Energizer battery, although the name of delirium behind a layer of leaked electrolyte is almost invisible.
Here is the other side. Expiration date until December 2027.
I have leaked other famous batteries, including the most expensive Duracell. However, cheap ones also flow.
Moreover, I cannot say that cheap ones flow more often than expensive ones. The probability is approximately the same. In this box I had about a hundred different discharged batteries. One flowed.
Three more leaked (though not so much) alkaline batteries from another box - Fujitsu, Sputnik, Auchan.
By the way, batteries can start to leak only after they are discharged. That is why it is almost impossible to come across an unused leaky alkaline battery, but salt ones can leak after long storage. It's just that alkaline ones retain their charge (although not completely) for decades, and salt completely loses its charge in five years.

The main topic of my blog is technology in human life. I write reviews, share experiences, talk about all sorts of interesting things. My second project - lamptest.ru. I test LED bulbs and help figure out which ones are good and which are not so good.
