Charles,

I think that's essentially the same battery that Lowell recently used. At
least the size, capacity and appearance look the same. It may have been
marketed under a different name, or have some internal difference from the
exact model he used.

I would check with him, although you will probably need to wait until later
in the day, since he's teaching again.

Matt

Subject: [FLEAA] C/1 capacity of EnerSys 95?

Does anyone know what the real-world C/1 capacity of the EnerSys 95 battery
is?

There are no specs for this battery on the company's website, and in fact no
listing and no mention of this battery at all, at least not that I could
find.  Company officials claim 80Ah @ C/1, but that sounds rather optimistic
to me from 95Ah @ C/20.  I would think 70Ah @ C/1 would seem more realistic.
I need a reality check from the marketing hype here.  Anyone know from
experience with this particular battery what the real 1-hour discharge
capacity is?

Something else for which I need a reality check is company officials' claim
that as long as a pack of EnerSys 95's is used with a central balancing BMS,
it can be deep cycled to 80% DOD ***every single cycle*** and still deliver
greater than 80% of original capacity for more than 5 years and 1250 cycles.
I need a little help here.  All of my experience is with advanced chemistry
batteries, none with PbA.  But my understanding from what I've always read
and been told about AGMs is that they shouldn't generally be cycled deeper
than 50% DOD very often and that if you regularly cycle them to 80% DOD, you
will murder them within 6 to 12 months.  So this claim by EnerSys of a
5-year/1250-cycle life @ 80% DOD, to 80% of original capacity -- is this
also just more hype and hyperbole, or am I missing something here?  Again,
anyone know from experience with this particular battery?

Thanks,

Charles Whalen
