Nah A lot of it is wowserism . Nothing different has happened yet .With my 1.4V I have had them at 40V and a big slab of current for a few seconds . See if I could blow any dendrites out or anything like that looking for indicators that something has changed . No change .
Had them on slow charge 20 to 50 mA after above treatment and they seem to be charging up pretty well. Will know more tomorrow as to whether my churning them up does revive them or just makes them discharge internally more quickly or just stuffs them completely.
I like to be testing these limits ,its the only way to real knowledge as dangerous as it may be. You know the way to pick the bomb maker, with the missing fingers. My mate at 16 blew the roof up 3 inches on his house making gunpowder.
The laptop batteries I remembered being recalled because one battery caught on fire . There was no mention of being on his lap and I wonder who made that up. Shoot a link in if you think that is correct.I know there are a lot of claims out there and some early poor construction but good tangible stuff ...ain't seen it.
All lead acid batteries give off hydrogen gas when charged and it was the big "NOT TO DO" cause they might explode . Right...as above thousands later no explosions and a heavy smoker. Come to think of it despite the wowserism try and light a bushfire with a cigarette . Bloody impossible in my experience with cigs no mater what they say ,maybe tossing the match but not the cig.
Don't know where you get this die with honour rubbish but it is exactly that. I doubt you know that much about the battery business by experience , more by discussion and hearsay. Ill see what I can find on Valence technology and get back to you. I'd like to saw one of their batteries in half and have a look at its innards . Thats the only way to get real knowledge . Put a hacksaw through the middle of a 9 V battery (discharged,blade through the terminals and down)and most would be surprisedat how its done .

Seems like they are still at it !
