Hi, just thought I'd share a somewhat surprising occurrence.
In the process of moving I stumbled across an old radio receiver, long since forgotten.
In it were four really old GP2700 cells. They had been sat there for years.
I thought, what the heck, why not give them a go in my C9000, expecting nothing more than a compete fail and dead cells all over.
What happened surprised me.
Started a break in cycle. No high warning, but at the same time nothing else either.
Voltage was around 0.05, 0.1 on all four.
5 minutes passed, still nothing, 0 mah on the display. Then the first one came to life, started crawling up slowly, accepting the charge, the other three followed.
About 10 minutes they all clicked, and jumped up to 1.40 V, roughly.
After two additional break in cycles they all deliver just over 2200 mah, back from beyond the grave.
Seriously lucky, or something to be expected? I for one did not expect it, based on experience from other cells.
Just thought I'd share.
