The physicist named the main danger of storing low batteries in devices

Low batteries damage remote controls, wall clocks, flashlights, children's toys and other equipment that may not be used for months. Alexey Yurasov, Doctor of Physico-Mathematical Sciences, Professor of the Department of Nanoelectronics at RTU MIREA, told about this on Wednesday, July 1.

According to the expert, the cause of damage is not the discharge of the battery, but the chemical processes that continue inside the battery after the end of its normal service life. As the battery's chemical system is discharged, it loses stability, chemical reaction products gradually accumulate inside the case, internal pressure increases, and metal elements begin to corrode, the physicist explained.

"Most often, you can see a white, bluish or greenish coating near the contacts of the battery compartment. Some people perceive it as ordinary dirt, but in fact it is the products of chemical reactions and corrosion. Such substances can destroy metal contacts, impair conductivity and gradually damage the current—carrying elements of the device," Yurasov said in an interview with Lenta.Ru .

He added that the process develops even when the device is turned off, because after the battery is discharged, the chemical reactions inside it do not stop completely. Over time, this can lead to a violation of the tightness of the housing and leakage of the electrolyte to the outside, the specialist warned.

The unique installation will help turn manure and food cleaning into useful substances.

Earlier, on June 20, Evgeny Zhuchkov, a technical expert at the NANFU brand, told Izvestia that used batteries should not be thrown away with ordinary garbage — this not only harms the environment, but can also result in a fine.

In turn, Dmitry Bondar, a public figure and housing and communal services expert, warned in an interview with RT that it was forbidden to throw a number of items into standard dumpsters in the yard. Such waste includes mercury thermometers, energy-saving lamps, batteries, electronics, car tires and construction debris. 360.ru .

Bondar clarified that it is better to take the batteries to special reception points, NSN reports.
