For many years I've read that high current charging depreciates any battery
faster than lower current charging. The exception is lead batteries, where
some (possibly short) period of initial high current "slam" can actually
extend cycle life. Back in the 1990s, Hawker used to recommend 1C to
Yes, unfortunate and well known (as well as outrageous, IMO).
But would it have been worse if you used DC charging more than once a week, as
they warned against?

On the flip side, my 2013 is the only model that can be programmed to take an
80%, as opposed to 100 charge, and I’ve only lost 1 power bar in 7 ys.
BTW, it’s for sale for 9k in So OR, as I’ve got the hotties to do a Bolt
with quite a bit more range.

I have a very small PEM (proton exchange membrane) fuel cell from a hydrogen
fuel cell science kit I got when I was much younger. I wonder if it is any
more efficient at converting water/electricity into H2/O2. You could
theoretically just capture the H2 it produces, then feed it back to the PEM

The 1.4 grams is the amount of oxygen that can dissolve in a liter of water.
Water is about 89% oxygen by weight so a liter of water would electrolysis

If I recall, this is a very inefficient way to get oxygen due to the strong

Hi All,
[The following is perhaps only of (any?) interest to Leaf owners, my apologies
for wasting everyone else's time)]:
Our 2011 Leaf (56K miles) just this week started reporting 5 (white) bars (& 2
red, which Nissan says is “7 bars”).
Prior to ending my daily 60 mile roundtrip commute ~4

I have one somewhere that someone gave me that doesn't work very well.
Apparently, the "molecular sieve" is consumable, and must be replaced
periodically, and is a fair portion of the cost of the whole
The oxygen concentrators use Zeolite; it absorbs nitrogen under pressure;
the result is air at over 90% oxygen. The pressure is dropped and the
nitrogen escapes into the room and the process happens again. If you were
in the tire business, this is how you get the nitrogen for tires and exhaust

Your link works. Not sure why my first attempt didn't.

The link worked just fine for me. I find that their results are astoundingly
bad. Even with their "better" charging method, they claim a battery is end of
life after 36 charge cycles. Excuse me! Anyone else find that not quite
right? I wonder what they were doing to those poor batteries to

Hi Peri,
I don't have personal experience with Tesla, but I do with other OEMs.
It is very safe to say that the BMS is preventing just that sort of
problem.
When I read the article, it was about testing to destruction, not about
how to do safe, long-term charging. Yeah, FUD again.

Hi Robert,
"How do those little battery powered O2 generators work?"
If you are referring to "Inogen" They are not actually oxygen genators.
Rather they are oxygen concentrators. They extract free oxygen from the air while
releasing the nitrogen back into the air.
