Testing a 40-Year-Old SAFT Battery: Does It Still Work? SAFT wasn't interested. :-( EN, HU, RU sub. 

I wanted to contact SAFT to let them know about this video, but they have not responded to any of my attempts. It's a shame. :-(
In my father's legacy, I found a SAFT lithium battery from 1983. Does it still hold any charge after these 4 decades? And can SAFT's quality truly stand the test of time? Dive in with me to uncover this intriguing find. Could this be one of the longest-lasting batteries? Watch this video and find out!
