Why did batteries from 20 years ago corrode and ruin electronics and why doesn’t this happen anymore?
In: 0
Alkaline batteries still leak and still ruin electronics. The problem is the dielectric the batteries are made with. The liquid in the battery leaks out and corroded metal.
If you can find dry cell batteries, they do not have the corrosive fluid inside them and do not leak. Those are perfect for devices like remote controls that sit on a table for long times and do not need high energy density or super long life.
Modern electronics use different battery chemistry which does not contain the alkaline fluid. I have seen devices the use internal lipo batteries that charge from a usb port instead of using AA batteries.
