[EVDL] "Zero volts = OK for LiFePO4" (was: A123 ALM 12V7 Batteries now charging)
The "zero volts" data was presented on this list many years ago. I
remember it well, but a brief search of the archives did not turn it
up. Very well documented tests were performed and results presented
on this list showing that LiFePO4 cells were not only unharmed by
discharging them to zero volts, the internal resistance actually went
down after discharging to zero volts, improving the specific power.
I know that A123Systems did extensive internal testing (unpublished)
on this effect and was on the verge of patenting the "discharge to
zero" process, but then found out that this was already in the public
domain. (I was the one that told them about the results presented on
the EVDL.)
If you don't want to take my word for the facts, and absolutely must
see the data yourself, do the search of the EVDL archives and find
the thread on the subject. Maybe 7 years ago?
