I'm going with the explanation that it is cracked inter-cell connections
that do that. Actually, I think it is usually where the post connects to an
electrode at one end or the other. A great majority of the time I've been
able to get it going again by whacking each post smartly (stupidly?) with a
hammer. The battery still needs to be replaced, but the car can be moved.
One of the moments that make me proud was that after I taught my then-teen
aged daughter that trick she was with my wife when I was out of town. The
car died in traffic and had no electrical. Daughter found a hammer in the
trunk, popped the hood and had them on the road in no time. BTW - bad
connections on the clamps react differently. Being exposed to air, they form
a layer of oxide that gets worse as more current flows. Internal connections
seem to weld together a bit as more current flows, producing a weird
increase in starter speed as the starter is held on.
I never saw this failure mode before the mid-'80s. At that time it was
associated with the new-at-the-time side post batteries, but I saw it on
even top-post batteries. I've replaced probably a dozen that have failed
that way since then.

Get a new battery. Even one deep discharge event can kill a battery's
capacity.
Also have the dealer make sure that the charging voltage is correct.
There is a TSB out for a situation which makes the car run an abnormally
high charging voltage, which can kill batteries.
The TSB is # 05-034, Headlights Dim or DTC P1298 Is Stored in the
ECM/PCM. It happened to our 2003 Accord and the dealer replace the
fuse box to correct it. Even though our car was out of warranty Honda
covered the cost 100% because it was a known defect.
