battery chemistry - What makes primary batteries leak on very deep discharge?


From my experience, if a primary (alkaline or zink) battery is left in a device with very low consumption (like a remote control, or a quartz watch) then at some point all the energy is drained and later the battery electrolyte leaks and damages the device.


What exactly makes batteries leak on very deep discharge? Do all primary batteries behave this way?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
