Joule Smasher Led Flasher - Dud CR2032 cells

 I should have known better. Buying no-name batteries is a real mistake.

After the used CR2032 cell ceased working I changed it for a fresh cell from the packet below. 


 

Almost immediately I was suspicious.Test results show it was next to useless. It stopped somewhere between 9am yesterday and today. Say 34.5 days. I mean really? Even the rubbish AG3 cell lasted 19 days in the same test fixture. What a waste of money.



Meanwhile, the AA battery just keeps powering along on-track for 10 years of life.
