Cum prelungești viața bateriilor cu o gumă de șters? Trucul care le readuce la viață • Newsweek România

A common household trick suggests using an eraser to clean battery terminals, potentially restoring functionality to dead batteries. This method removes dirt and oxidation that can hinder electrical contact, allowing devices to work again. Experts recommend this technique as it effectively cleans without damaging the battery contacts. While it doesn't regenerate the internal chemistry of batteries, it can extend their usable life by ensuring better connectivity. Proper application involves gently rubbing the terminals and cleaning any debris afterward to avoid leaving particles inside devices.
